saying: ``Clergy and French, they are one and the same thing.''

ALBINO, a biological term (Lat. albus, white), in the usual

acceptation, for a pigmentless individual of a normally pigmented

race. Among some flowering plants, however, the character

has become one of specific rank, .and among animals we have

in the polar bear and the Greenland hare instances where

partial albinism--for in them the eyes are black and other

parts may be pigmented--has also become a specific character.

A true or complete albino is altogether devoid of pigment.

One result of this among the Vertebrata is that the eyeball

is pink in colour, since the cornea, iris and retina being

transparent, the red blood contained in the capillaries is

unmasked by the absence of pigmentary material. In man, and

doubtless also in lower forms, the absence of this pigment

produces the well marked albinotic facies. This is a condition

in which the eyelids are brought into a nearly closed position

accompanied by blinking movements and a general wrinkling of

the skin around the immediate neighbourhood of the eyes. It

is the result of the too great intensity of the light incident

upon the retina, and which in normal eyeballs is adequately

diminished by the absorptive power of the pigmentary material.

In a complete albino not only is all pigment absent in the

skin, but also that which is normally present in deeper

organs, such as the sympathetic nervous system and in the

substanlia nigra of the brain. There is some reason to

believe that a peculiar condition found in the majority of

human albinoes, and knovn as nystagmus, is correlated with

the absence of pigment in the central nervous system. This

condition is one marked by unsteadiness---a sort of flickering

rolling--of the eyeballs, and it becomes more marked as they

endeavour to adjust their accommodation to near objects. It

is thought to depend upon some connexion, not yet anatomically

demonstrated, between the third cranial nerve and its nucleus

in the floor of the iter and the substantia nigra.

In addition to complete albinism, there exist, however, various

albinotic conditions in which more or less pigment may be

present. Familiar instances of this partial albinism is

seen in the domestic breed of Himalayan rabbits. In these

animals the eyeball and the fur of the body are unpigmented,

but the tips of the ear pinnae and extremities of the fore

and hind limbs, together with the tail, are marked by more

or less well defined colour. One remarkable feature of these

animals is that for a few months after birth they are complete

albinoes. Occasionally, however, some are born with a grey

colour and a few may be quite black, but ultimately they

attain their characteristic coat. There is some reason to

believe, as we shall see later, that in spite of the presence

of a little pigment and of occasional wholly pigmented young

ones, Himalayans must be regarded as true albinoes. Other

individual rabbits, but belonging to no particular breed,

are similarly marked, but in addition the eyeballs arc

black. Some domesticated mice are entirely white with the

exception that they have black eyeballs; and individuals

of this type are known in which there is a reduction of

pigment in the eyeballs, and since the colour of the blood

is then partially visible these appear of a reddish-black

colour. Such cases are interesting as representing the last

step in the graded series through which the condition of

complete pigmentation passes into that of complete albinism.

There is evidence, as shown by G. M. Allen, that partial

albinism is a condition in which pigment is reduced around

definite body centres, so that unpigmented areas occur

between the pigment patches or at their borders. In the

mouse, ten such centres may be distinguished, arranged

symmetrically five on either side of the median plane---a

cheek patch, neck patch, shoulder patch, side patch and rump

patch. Various degrees in the reduction of the pigment

patches up to that of complete elimination may be traced.

Some animals are wholly pigmented during the summer and

autumn, but through the winter and spring they are in the

condition of extreme partial albinism and become almost complete

albinoes. Such instances are found in the Scotch blue hare

(Lepus timidus), in the Norway hare, in the North American

hare (H. americanius), in the arctic fox (Canis lagopus),

in the stoat and ermine, and among birds, in the ptarmigan,

and some other species of Lagopus. How the change from the

autumnal to the winter condition takes place appears not to

be definitely settled in all cases, and accurate observations

are much to be desired. In the case of the Norway hare,

it has been stated that a general moult, including all the

hairs and under fur, takes place and new white hairs are

substituted. The process of moulting is said to begin in

the middle of autumn and is completed before the end of

December, by which time the fur is in its winter condition,

and is closer, fuller and longer than in summer (Naturalists'

Library, vol. vii.). On the other hand, it has been stated

that during the whole of the transformation in the fur no

hairs fall from the animal, and it is attributed to an actual

change in the colour of the hair (Edinburgh Philosophical

Journal, vol. xi. p. 191). In the case of the American

hare, however, some very careful observations have been

made by F. H. Welch. In this animal the long hairs (which

form the pile) become white at their extremities, and in

some of them this whiteness extends through their whole

length. At the same time, new hairs begin to develop and

to grow rapidly, and soon outstrip the hairs of the autumn

pile. From their first appearance these new hairs are white

and stiff, and they are confined to the sides and back of the

body. It is not clear from Welch's account what is the cause

of the whiteness of the tips of the hairs of the autumn coat,

but his figures suggest that it is due to the development

of gas in the interspaces between the keratin bridges and

trabeculae of the hairs. There is nothing to show whether

the pigment persists or is absorbed. Probably it persists.

In this event, the whiteness of the tips will be due to the

scattering or irregular reflexion of the incident rays of

light from the surface of the numerous gas bubbles. In the

case of the ptarmigan the evidence is clear that the existing

autumnal feathers do change, more or less completely, to

white. But the evidence is not conclusive as to whether any part

of the winter condition is additionally produced by moulting.

The condition of albinism thus assumed as a seasonal variation

is never complete, for the eyes at least retain their pigmented

state. The reason of this is readily understood when it is

borne in mind how disadvantageous to the function of sight is

the unpigmented condition of an albino's eyeball; a disadvantage

which would be probably much accentuated, in the cases now under

consideration, by the bright glare from the surface of the

snow, which forms the natural environment of these animals

at the particular period of the year when the winter change

occurs. In some cases, as in all the varying hares, in addition

to the eyes retaining their normal pigmentation, areas similar

in extent and situation to those on the Himalayan rabbits also

retain their pigmentation; and in the ptarmigan there is a

black band on each side of the head stretching forwards and

backwards from the eyeball, and the outer tail feathers are black.

Albinism is restricted to no particular class of the animal

kingdom; for partial albinism at least is known to occur in

Coelentera, worms, Crustacea, Myriapoda, Coleoptera,Arachnida and

fishes. The individuals in which this diminished pigmentation

is found are for the most part those living in caves, and

it is probable that their condition is not truly albinotic,

but only temporary and due to the absence of the stimulus of

light. This may be also true of some of those instances

that have occurred among frogs, in Proteus, and with an

axolotl once possessed by the present writer. This latter

animal was quite white, with the exception of the black

eyeballs. At the end of four weeks after it was first

purchased the dorsal or upper surface of its external gills

developed a small amount of dark pigment. Within the next

few weeks this increased in quantity and the dorsal surface

of the head and of the front end of the trunk began to be

pigmented. The animal died at the end of the eighth week, but

it is possible that had it lived it would have become wholly

pigmented. But, apart from these instances, albinism is known,

according to W. E. Castle, who cites it on the authority of Hugh

M. Smith, to occur among a breed of albino trout, which breed

true and are reared in the State fish-hatcheries of America.

With birds and mammals, however, there is no doubt that complete

albino individuals do occur; and among species which, like the

jackdaw, certain deer and rabbits, are normally deeply pigmented.

Albinism occurs in all races of mankind, among mountainous

as well as lowland dwellers. And, with man, as with other

animals, it may be complete or partial. Instances of the

latter condition are very common among the negroes of the United

States and of South America, and in them assumes a piebald

character, irregular white patches being scattered over the

general black surface of the body. Occasionally the piebald

patches tend to be symmetrically arranged, and sometimes the

eyeballs are pigmentless (pink) and sometimes pigmented (black).

According to A. R. Gunn, of Edinburgh Dniversity, who has

recently been investigating the subject of albinism in

man, there is reason to believe that a condition of piebald

albinism occurs also in Europeans (Scotsmen). He has examined

subjects in which the whole of the hair of the body is

white, but the eyeballs are pigmented, often deeply; and,

conversely, he has seen cases in which the eyes are pink

but the hair is pigmented. The hair and the eyes may be

regarded as skin patches, in which sometimes the one and

sometimes the other is pigmentless. He believes that, were

it not for the generally very pale colour of white-skinned

races, this piebald condition would be as manifest in

them as in negroes, over the whole surface of the body.

In complete human albinoes, albinism is correlated, in addition

to nystagmus, with a peculiar roughness of the skin, making it

harsh to the touch. The skin is also milky-white in appearance.

According to C. J. Sehgmann, there exists among the Papuans

an albinotic race whose skin varies in colour from a

pink-white to that of cafe au lait; the eyes are generally

greenish, hazel or brown, and the hair is tow-coloured. The

skin where unexposed is pinker than that of a normal North

European. Like complete albinoes, this race suffers from

photophobia, and is characterized by the albinotic facies.

Before we can inquire into the cause and meaning of albinism it

will be necessary first to consider the nature Of pigmentation.

It has recently been ascertained that the coloration of

certain sponges is due to the interaction of an oxydizing

ferment, tyrosinase, upon certain colourless chromogenic

substances. In 1901, Otto v. Furth and Hugo Schneider showed

that a tyrosinase could be obtained from the blood of certain

insects, and, acting upon a chromogen present in the blood,

converted it into a pigmentary substance of melanin-like

nature. Hans Przibram also extracted a tyrosinase from the

ink-sac of Sepia, and, causing it to act upon a watery

solution of tyrosin, obtained a black pigment. From the blood of

Bombyx mori, fe. von Ducceshi has also obtained a tyrosinase.

Subsequently (1903) L. Cuenot, in order to explain certain

features in the hereditary transmission of coat colour in

mice, postulated the hypothesis that the grey colour of

the wild mouse (which is known to be a compound of black,

chocolate and yellow pigments) may be due either to the

interaction of a single ferment and three chromogens, or vice

versa, to one chromogenic substance and three ferments.

Since then (1904) Miss Florence Durham has shown that if

the skins of young or embryonic mammals (rats, rabbits and

guinea-pigs) be ground up and extracted in water, and the

expressed juice be then incubated with solid tyrosin for

twenty-four hours, with the addition of a very small amount

of ferrous sulphate to act as an activator, a pigmentary

substance is thrown down. The colour of this substance

is that of the pigment in the skin or hairs of the animal

used. Miss Durham interprets her results as indicating that the

skin of these pigmented animals normally secretes one or more

tyrosinases. The same result was obtained from the skins of

some unhatched chickens. The skins of albinoes gave no results.

Not only have such resuits been obtained with sponges,

Insects, cephalopods, birds and mammals, but Em. Bourquelot

and G. Bertrand have shown that certain fungi, the tissues

of which, when exposed to the air by injury, become

immediately coloured, do so owing to the action of tyrosinase

upon one or more chromogenous substances present in the

plant. We may conceive, then, that a pigmented animal

owes its colour to the power that certain tissues of its

body possess to secrete both tyrosinases and chromogenic

substances. And the period at which this process is most

active is at birth, or preceding it or immediately succeeding

it. In spite of the inquiry being only in its initial stages,

there is already good evidence to believe that Cuenot's

theory is correct, and that an albino is an individual whose

skin lacks the power to secrete either the ferment or the

chromogen. It forms one but not both of these substances.

A moment's consideration, however, will show that, while

an albino may be an individual in which one or more of

the complementary bodies of pigmentation are absent, a

pigmented animal is something more than an individual which

carries all the factors necessary for the development of

colour. For it must be borne in mind that animals are not only

coloured but the colour is arranged in a more or less definite

pattern. The wild mouse, rat and rabbit are self-coloured,

but the domesticated forms include various piebald patterns,

such as spotted forms among mice, and the familiar black and

white hooded and dorsal-striped pattern of some tame rats.

Colour, therefore, must be correlated with some determinant

(determining factor) for pattern, and it cannot, therefore,

exist alone in an animal's coat. And we must conceive that

each kind of pattern---the self, the spotted, the striped,

the hooded and all others---has its own special determinant.

Given the presence of all the necessary determinants for

the development of pigment in a mammal's coat, some or all

of the hairs may bear this pigment according to the pattern

determinants, or absence of pattern determinants, which the

cells of the hair papillae carry. And this brings us to

the question as to whether in a piebald animal the pigmented

hairs are in any way different from the pigmentless or white

hairs. No adequate investigation of this subject has yet

been made, but some observations made by the author of this

article, on the piebald black and white rat, show that

differences connected with the microscopic structure exist.

There is thus evidence that colour is correlated with other

factors which determine pattern. And this leads to the

inquiry as to whether albinoes ever exhibit evidence that they

carry the pattern determinants in the absence of those for

pigmentation. For it is to be expected a priori that, since

albinoes were derived from pigmented progenitors and may at

any time appear, side by side with pigmented brothers, in

a litter from pigmented parents, they would be carrying the

pattern determinants of some one or other of their pigmented

ancestors. Now we know, from the numerous experiments in

heredity which have resulted since the rediscovery of Mendel's

principles, that an individual may carry a character in one of two

conditions. It may be carried as a somatic character, when it

will be visible in the body tissues, or it may be carried as a

gametic character, and its presence can only then be detected

in subsequent generations, by adequately devised breeding tests.

With regard to pattern, the evidence is now clear that

albinoes may carry the determinants in both these ways.

So far as they are carried gametically, i.e. by the

sex-cells, it has been shown by Cuenot and G. M. Allen for

mice, by C. C. Hurst for rabbits, and by L. Doncaster and

G. P. Mudge for rats, that in a cross between a coloured

individual of known gametic purity and an albino, the

individuals of the progeny in either the first or second, or

both generations, may differ, and that the difference in some

cases wholly depends upon the aihino used. It has been shown

that the individuals in such an offspring may bear patterns

which never occurred in the ancestry of the coloured parent,

but did in that of the albino; and, moreover, if the same

coloured parent be mated with another individual, either

albino or coloured, that their offspring may never contain

members bearing such patterns. The particular pattern

will only appear when the coloured parent is mated with

the particular albino. And yet the albino itself shows no

somatic pattern or pigment. So clear is the evidence on

this point that any one adequately acquainted at first hand

with the phenomena, by employing an albino of known gametic

structure and mating it with a coloured individual, also

of known gametic constitution, could predict the result.

With respect to albinoes carrying pattern as a visible somatiu

character, i.e. in the body cells, no definite evidence

has as yet been published. But W. Haacke has described a

single albino rat, in which he states that the hairs of the

shoulder and mid-dorsal regions were of a different texture

from those of the rest of the body. And it is possible

that this albino, had it developed colour, would have been

of the piebald pattern. But the author of this article has

quite recently reared some albinoes in which the familiar

shoulder hood and dorsah stripe of the piebald rat is

perfectly obvious, in spite of the absence of the slightest

pigmentation. The hairs which occupy the region which in

the pigmented individual is black, are longer, thinner and

more widely separated than those in the regions which are

white. As a result of this, the pink skin is quite visible

where these hairs occur, but elsewhere it is invisible. Thus

these albinocs exhibit a pattern of pink skin similar in form

with the black pattern of the piebald rat. Moreover, some

of the albinoes possess these particular ``pattern'' hairs

all over the body and obviously such individuals are carrying

the self pattern. There are other details into which we

cannot here enter, but which support the interpretation put

upon these facts, i.e: that these particular albinoes are

carrying in the soma the pattern determinants simultaneously

with the absence of some of the factors for pigmentation.

Not only do albinoes thus carry the determinants for pattern,

but it has been known for some time that they also carry

gametically, but never visible somatically, the determinants

for either the ferment or the chromogen for one or more

colours. L. Cuenot was the first to show this for albino

mice. He was able by appropriate experiments to demonstrate

that when an albino is derived (extracted) from a coloured

ancestry, and is then crossed with a coloured individual, both

the colour of the pigmented parent and of the pigmented ancestry

of the albino may appear among the individuals of the offspring.

Immediately subsequent to Cuenot, G. M. Allen in Ameriia

demonstrated the same Jact upon the same species of rodents.

C. C. Hurst, more recently, has shown that albino rabbits.

whether pure bred for eight generations at least, or extracted

from pigmented parents, may carry the determinants for black

or for black and grey. In this latter case the determinants

for black are carried by separate gametes from those carrying

grey, and the two kinds of sex-cells exist in approximately

equal numbers. This is likewise true of albino mice when

they carry the determinants for more than one colour.

Since Hurst's work, L. Doncaster and G. P. Mudge have both

shown that albino rats also carry in a latent condition

the determinants for black or grey. The experiments of the

latter author show that, if a gametically pure black rat be

crossed with an albino derived from a piebald black and white

ancestry, all the offspring in successive litters will be

black; but if the same black parent be crossed with albinoes

extracted from parents of which One or both are grey, then both

grey and black members will appear in the successive litters.

The proportions in which the various coloured individuals

appear are approximately those demanded by the Mendelian

principle of gametic purity and segregation. Cuenot and Hurst

have also shown that when albinoes of one colour extraction

are crossed with albinoes of another colour extraction the

segregation of the colour determinants in the gametogenesis

of the albinoes takes place in precisely the same way that it

does in the gametogenesis of a pigmented individual; that is,

in Mendelian fashion. Or, to express it otherwise, an albino

extracted from yellow parents, bred with an albino extracted

from black parents, will give an albino offspring whose

gametes in equal numbers are bearers of the black and yellow

determinants. And when one of these albinoes is bred with

a pure coloured individual, a mixed offspring will appear in

the first generation. Some of the individuals will be one

or other of the two colours, the determinants of which were

borne by the albino, and others the colour of the pigmented

parent. But in such albino crosses the colour characters

are latent because albinoes do not carry the whole of the

complements for colour production. They carry only some

determinant or determinants which are capable of developing

colour when they interact with some other determinant or

determinants carried alone by pigmented individuals. Whether

albinoes carry the tyrosinase or other ferment, or whether

they carry the chromogen or chromogens, is not yet settled.

Miss Durham's work suggests that they carry the latter. But

that they never bear both is proved by the fact that, when

albinoes are crossed with each other, none but albinoes ever

result in the offspring. One apparent exception to this rule

only is known, and this almost certainly was due to error.

It is not only among albino animals that colour factors

are carried in a latent condition, but also in white

flowers. W.. Bateson has shown this to be the case for the

sweet-pea (Lathyrus odoratus), var. Emily Henderson,

and for certain white and cream stocks (Matthiola.) When

white Emily Henderson (the race having round pollen grains)

is crossed with a blue-flowered pea, purple offspring

result. Similarly, when white Emily Henderson (long pollen

grains) is crossed with white Emily Henderson (round pollen

grains), the offspring wholly consists of the reversionary

purple type, and sometimes wholly of a red bicolor form known

as ``Painted Lady.'' These two types never appear in the same

family. With the stocks, when a white-flowered and hairless

form is crossed with a cream-flowered and hairless one, all

the offspring are purple and hairy. Bateson considers that

the purple colour is due to the simultaneous existence in

the plant of two colour factors which may be designated by

C and R. If either one of these two is absent the plant is

colourless. Cream-coloured flowers are regarded as white

because cream is due to yellow plastids and not to sap

colour. Thus the cream plant may carry C and the white

one R. When they are crossed the two factors for colour

production are brought together. Obviously, we may regard C

as a tyrosinase and R as a chromogen, or vice versa; and in

the case of the white sweetpea crossed with a blue-flowered

one, and producing purple offspring, we may imagine that

the white flower brought in an additional tyrosinase or a

chromogen not present in the blue flower, which, when combined

or mixed with the chromogen or tyrosinase for blue, gave

purple. A similar explanation may apply to C. Correns's

experiment, in which he crossed white Mirabilis jalapa with

a yellow form, and always obtained red-flowered offspring.

In heredity, complete albinism among animals is always

recessive; and partial albinism (piebald) is always recessive

to complete pigmentation (self-coloured). When an albino

mouse, rat, guinea-pig or rabbit is crossed with either

a pure self or pure pied-coloured form, the offspring are

similar to, though not always exactly like, the coloured

parent; provided, of course, that the albino is pure and

is not carrying some colour or pattern determinant which is

dominant to that of the coloured parent used. No albinoes,

in such a case, will appear among the first generation,

but if the individuals of this (F.1) generation are crossed

inter se or back crossed with the albino parenr, then

albino individuals reappear among the offspring. In the

former case they would form one-quarter of the individuals

of this second (F.2) generation, and in the latter, one-half.

The recessive nature of albinism and its distribution in

Mendelian fashion is almost certainly as true for man as

for lower forms. This has been shown by W. C. Farabee for

negroes in Coanoma county, Mississippi. The facts are as

follows. An albino negro married a normal negress. They had

three children, all males. All three sons married, and two

of them had only normal children, judged of course by somatic

characters. But the third son married twice, and by the

first wife had five normal and one albino children, and by

the second, six normal and three albino children. If we

assume that the two negresses which the third son married

were themselves carrying albinism recessive --an exceedingly

probable condition considering that albino negroes are not

uncommon---the result is accurately in accordance, as W. E.

Castle has shown, with Mendelian expectation. For there is

expected in the offspring of this third son coloured individuals

and albinoes in the proportion of 3:1. There is actually 11:4,

which is the nearest possible approximation with the number 15.

The operation of Mendelian processes in human heredity

is further shown by the close relationship that exists

between the appearance of albinoes and cousin marriages.

An albino is a homozygote; that is, all its gametes are

carrying the character of albinism and none of them bear the

alternative character --the allelomorph---of pigmentation. By

pigmentation is here meant all those factors which go to its

production. Now such a gametic (egg or sperm) constitution

can only result when two individuals, all or some of whose

gametes are pure with regard to the character albinism, meet in

fertilization. Hence it is readily seen that it is among

cousin marriages that the greater probabilities exist that

two individuals bearing identical characters will meet, than

in the population at large. This can be illustrated in the

following scheme. Let A stand for a pure albino and (A)N

for a normal person, who nevertheless carries the character

albinism (A) recessive. Then, in the scheme below, if Ab

and (A)Nb are two brothers who both marry normal wives

N, their children N(A) in the first case will be all normal

in appearance but will be carrying albinism recessive; and

in the second case some will be pure normal individuals

N, and some will be like the children of the first brother,

i.e. N(A). Now, if one of these latter children of the

second brother marries a cousin---a child of the first

brother,---their offspring, if large enough, will consist of

some pure normals N, impure normals N(A), and of albinoes A.

Ab X N (A)Nb X N

N(A) N(A)+N

N+2N(A)+A

No other rational explanation of the close relationship

between albinism and cousin marriages is at present

forthcoming. And, when the whole facts are borne in

mind, there can be no reasonable doubt that the Mendelian

principles offer an intelligible solution of the problem.

A popular conception exists that albinoes are less

constitutionally strong than the pigmented individuals of

the same species. In support of this belief there is more or

less scientifically ascertained evidence. Conversely, there

is, however, conclusive evidence that in some instances and

in respect of certain qeialities the opposite belief is true.

To deal with the former belief first, we have the remarkable

case cited by Charles Darwin on the authority of Professor I. J.

Wyman. In Virginia the paint-root plant (Lachnanthes

tinctoria) occurs abundantly, and Professor Wyman noticed

that all the pigs in this district were black. Upon inquiry

of the farmers he found that all the white pigs born in a

litter were destroyed, because they could not be reared to

maturity. The root of this plant, when eaten by white pigs,

caused their bones to turn to a pink colour and their hoofs

to fall off, but the black pigs could eat the same plant with

impunity. Partial albinism in this case was undoubtedly

correlated with some inherent constitutional defect, in

virtue of which the individuals characterized by it were

injuriously affected by the juices of a plant quite innocuous

to their pigmented brethren. Heusinger has shown that

white sheep and pigs are injured by the ingestion of certain

plants, while the pigmented individuals may eat them without

harm. In Devonshire and in parts of Kent the farmers entertain

a marked prejudice against white pigs, because ``the sun

blisters their skin.'' More remarkable is the case of certain

cattle, whose skin is piebald, marked by a general ground

colour over which are scattered patches of unpigmented coat.

In these animals, in certain inflammatory skin eruptions,

caused by the ingestion of harmful plants, the albinotic

areas are alone affected. And with certain cutaneous diseases

accompanied by constitutional disturbances which afflict

cattle, the affection in the skin appears on the patches

bearing white hairs, the other parts remaining apparently

healthy. Such cases suggest that we should be more correct

in regarding, not albinism as correlated with constitutional

defects, but rather pigmentation as correlated with powers

of immunity or increased resistance against certain injurious

processes. In the West Indies ``the only horned cattle

fit for work are those which have a good deal of black in

them; the white are terribly tormented by the insects and

they are weak and sluggish in proportion to the black.''

Coming to man, it is known that some albino negroes are peculiarly

sensitive to the bites of insects; and with Europeans it is a

generally observed fact that the fairer individuals are more

seriously affected by the bites of fleas and bugs than are darker

ones. Dr Twining, in the British Association Reports for

1845, p. 79, cites some instances described by Humboldt, who

says that the copper-coloured natives of the high plain of

Bogoto, and at a lower level on the Magdalena river, were

generally free from goitre. Professor Poffig, also cited

by Dr Twining, states that on the east side of the Andes in

Chile, in some of the races which live there, he did not see

a single case of goitre, and yet in the white inhabitants, who

live exactly as the natives, it prevails in a great degree:

Turning now to instances of the opposite kind, it is known

that silkworms which spin colourless cocoons are more resistant

to the attacks of a certain deadly fungus than are those

which spin the yellow ones. In some parts of North America

it is found that the white peaches are much less liable to

the attack of a disease known as the ``yellows'' than are

the yellow-fleshed ones. In the region of the Mississippi,

Farabee has observed that the albino negroes are taller and

broader than the black-skinned individuals. We may assume

that increased stature and breadth imply some sort of inherent

physical superiority, and if such an assumption is valid we

have in man evidence that albinism is correlated not with

constitutional defectiveness but with greater perfectness.

But the question as to whether albinoes are more or less

constitutionally vigorous than pigmented individuals of the

same species may be tested by exact measurement. In 1893 W. D.

Halliburton and T. G. Brodie, in ascertaining the physiological

pijoperties of nucleo-proteids, found that when they were

intravascularly injected into pigmented rabbits, coagulation

of the blood resulted, but of the eight albinoes which they

used, none clotted. At a subsequent period (1897) Halliburton

and J. W. Pickering showed that the three synthesized colloids

of Grimaux in the same way produced coagulation in pigmented

animals, but failed to do so in albinoes. Pickering, still

later, showed, in the case of four Norway hares, two of

which were injected while in their pigmented or summer

coat, and two while in their albino or winter coat, that

coagulation occurred in the former cases but not in the latter.

Quite recently, however, the author of this article has made

a more detailed examination of the question, operating upon

several hundreds of rabbits. And he found that all albinoes

do not fail to clot when intravascularly injected with

nucleoproteids. Only about 9% of them thus failed absolutely

to manifest any trace of coagulation. But about 7% showed

an exceedingly limited coagulation, in which the clot was

colourless and flocculent, and confined to the heart. The

rest gave a typical and more or less wide-spread coagulation.

Moreover, it was found that all the failures of coagulation

occurred when the nucleo-proteid used was obtained from pigmented

animals. When it was derived from albinoes no failures

occurred. All pigmented animals clotted when the nucleo-proteid

was derived from either source. The Himalayan rabbits reacted

like complete albinoes, and 12% of them failed to clot when

injected with nucleo-proteid extracted from pigmented animals.

The interesting fact was thus ascertained that all albinoes are not

alike. To students of heredity this is precisely what would

have been expected. For, as the facts above described show,

albinoes, though apparently identical externally, are yet the

carriers of different hereditary characters. Among albino

rats, for instance, the author of this article has reason to

believe, upon theoretical grounds resting on an experimental

basis, that probably no less than thirteen types exist.

With rabbits and mice there must be a still larger number.

In the intravascular coagulation experiments above described,

all the rabbits were carefully weighed, and the amount of

nucleoproteid injected until coagulation occurred was measured.

This would give for albinoes and pigmented individuals the

amount per kilogramme of body-weight required to kill in each

case, and would afford a measurement of the relative resistance

of the two races. It was found that the resistance of albinoes

towards the coagulative effects of injected nucleo-proteids

was to that of pigmented individuals as 1.5 to 1.0. In this

case, the greater constitutional vigour of the albino is

thus accurately demonstrated. But it does not necessarily

follow that with other materials and with other constitutional

qualities the state of things would not be reversed.

One other feature remains to be mentioned. Albinism appears,

in the processes of heredity, to be sometimes indissolubly

correlated with certain peculiar traits. It is well known

that the long-haired albino rabbit, called Angora, when at

rest, has the habit of swaying its head sideways in a peculiar

fashion. C. C. Hurst has shown that the long-haired and

albino characters are always accompanied in heredity with the

swaying habit. The Angora character never occurs without it.

ALBINONI, TOMASSO (c. 1674--c. 1745), Italian musician,

was born at Venice. He was a prolific composer of operas

attracting contemporary attention for their originality,

but is more remarkable as a composer of instrumental music,

which greatly attracted the attention of Bach, who wrote

at least two fugues on Albinoni's themes and constantly

used his basses for harmony exercises for his pupils.

ALBINOVANUS PEDO, Roman poet, flourished during the Augustan

age. He wrote a Theseis, referred to in a letter from his

intimate friend Ovid (Ex Ponto, iv. 10), epigrams which

are commended by Martial (ii. 77, v. 5) and an epic poem on

the exploits of Germanicus. He had the reputation of being

an excellent raconteur, and Quintilian (x. i. 90) awards him

qualified praise as a writer of epics. All that remains of

his works is a beautiful fragment, preserved in the Suasoriae

(i. 15) of the rhetorician Seneca, from a description of the

Voyage of Germanicus (A.D. 16) through the river Ems to the

Northern Ocean, when he was overtaken by the storm described

by Tacitus (Ann. ii. 23). The cavalry commander spoken of

by the historian is probably identical with the poet. Three

elegies were formerly attributed to Pedo by Scaliger; two

on the death of Maecenas (In Obitum Maecenatis and De

Verbis Maecenatis moribundi), and one addressed to Livia to

console her for the death of her son Drusus (Consolatio ad

Liviam de Morte Drusi or Epicedion Drusi, usually printed

with Ovid's works); but it is now generally agreed that they

are not by Pedo. The Consolatio has been put down as late

as the 15th century as the work of an Italian imitator, there

being no MSS. and no trace of the poem before the publication

of the editio princeps of Ovid in 1471. There is an

English verse translation of the elegies by Plumptre (1907).

ALBINUS (originally WEISS), RERNHARD SIEGFRIED

(1697-1770), German anatomist, was born on the 24th of February

1697, at Frankfort-on-Oder, where his father, Bernhard Albinus

(1653-1721), was professor of the practice of medicine. In 1702

the latter was transferred to the chair of medicine at Leiden,

and it was there that Bernhard Siegfried began his studies,

having for his teachers such men as H. Boerhaave and Nikolaus

Bidloo. Having finished his studies at Leiden, he went to

Paris, where, under the instruction of Sebastien Vaillant

(1669-1722), J. B. Winslow (1669-1760) and others, he devoted

himself especially to anatomy and botany. After a year's

absence he was, on the recommendation of Boerhaave, recalled

in 1719 to Leiden to be a lecturer on anatomy and surgery.

Two years later he succeeded his father in the professorship

of these subjects, and speedily became one of the most famous

teachers of anatomy in Europe, his class-room being resorted

to not only by students but by many practising physicians.

In 1745 Albinus was appointed professor of the practice of

medicine, being succeeded in the anatomical chair by his

brother Frederick Bernhard (1715-1778), who, as well as another

brother, Christian Bernhard (1700-1752), attained considerable

distinction. Bernhard Siegfried, who was twice rector of his

university, died on the 9th of September 1770 at Leiden.

ALBION (in Ptolemy 'Alouion; Lat. Albion, Pliny

4.16[30],102), the most ancient name of the British Islands,

though generally restricted to England. The name is perhaps

of Celtic origin, but the Romans took it as connected

with albus, white, in reference to the chalk-cliffs of

Dover, and A. Holder (Alt-Keltischer Sprachschatz, 1896)

unhesitatingly translates it Weissland, ``whiteland.''

The early writer (6th cent. B.C.) whose periplus is

translated by Avienus (end of 4th cent. A.D.) does not

use the name Britannia; he speaks of nesos 'Iernon kai

'Albionon (``island of the Ierni and the Albiones''). So

Pytheas of Massilia (4th cent. B.C.) speaks of ''Albion

and 'Ierne. From the fact that there was a tribe called

the Albiones on the north coast ot Spain in Asturia, some

scholars have placed Albion in that neighbourhood (see G. F.

Unger, Rhein. Mus. xxxviii., 1883, pp. 156-196). The name

Albion was taken by medieval writers from Pliny and Ptolemy.

ALBION, a city of Calhoun county, Michigan, U.S.A., on the

Kalamazoo river, 21 m. W. of Jackson. Pop. (1890) 3763;

(1900) 4519, of whom 622 were foreign-born; (1904) 4943; (1910)

5833. Albion is served by the Michigan Central and the

Jackson division of the Lake Shore and Michigan Southern

railways, and by an inter-urban electric line. The city has

a public park and a public library. The W. part of the city

has most of the factories; the principal manufactures are

flour, agricultural implements, windmills, gasolene engines,

harness and proprietary medicines. On a commanding site in

the E. part of the city is Albion College (Methodist Episcopal;

co-educational), embracing a College of Liberal Arts, a

preparatory department, a conservatory of music, a school of

art, a school of oratory, a normal course, and a commercial

department. The college was incorporated in 1835 as Spring

Arbor Seminary, and in 1839 by an amended charter was located

at Albion, where it was first opened in 1843 under the

name of the Wesleyan Seminary of Albion; in 1849 it became

the Wesleyan Seminary and Female Collegiate Institute,

with power to grant degrees to women only; but in 1861 the

present name was adopted and the college was permitted to

grant degrees to men and women. In 1906 it had a library

of 16,500 volumes, a faculty of 19, and an enrolment of 483

(211 being women). The municipality owns and operates the

water-works, the water-supply being obtained from artesian

wells. Albion was settled in 1831, was incorporated as

a village in 1866 and was chartered as a city in 1885.

ALBION, a village and the county-seat of Orleans county, New

York, U.S.A., about 30 m. W.N.W. of Rochester. Pop. (1890)

4586; (1900) 4477, (984 being foreign-born and 43 negroes);

(1905, state census) 5174; (1910) 5016. The village is

served by the New York Central & Hudson River railway, by the

Buffalo, Lockport & Rochester electric railway, and by the Erie

Canal. In Albion are the Western House of Refuge for Women

(a state institution established in 1890), a public park, the

Swan Library, and the county buildings, including the court

house, the jail and the surrogate's office; and about 2 m.

to the S.E. is the beautiful Mount Albion Cemetery. Albion

is the centre of the Medina sandstone industry, and lies

in the midst of a good farming region, of which it is the

principal shipping point, especially for apples, cabbages and

beans. The village manufactures agricultural implements,

vinegar, evaporated fruit, and canned fruit and vegetables, and

has two large cold-storage houses. Albion was settled in 1812,

was incorporated in 1823 and became the county-seat in 1825.

ALBITE, a mineral of the felspar group, belonging to the

division of the plagioclases (q.v..) It is a sodium and

aluminium silicate, NaAlSi3O8, and crystallizes in the anorthic

system. Like all the felspars it possesses two cleavages,

one perfect and the other less so, which are here inclined at

an angle of 86 deg. 24'. On the more perfect cleavage, which is

parallel to the basal plane (P), is a system of fine striations,

parallel to the second cleavage (M), due to twinning according

to the,``albite law'' (figs. 1 and 2). The hardness is 6,

and the specific gravity 2.63. The colour is usually pure

white, hence the name (from the Lat. albus) for the species.

Albite forms an essential constituent of many acidic igneous and

FIG. 1. FIG. 2.

crystalline rocks; Twinned crystals of Albite. in granites,

diorites, andesites, &c., it occurs as a primary mineral,

whilst in crystalline schists, phyllites and crystalline

limestones it is of secondary (metamorphic) origin. The

beautifully developed crystals so abundant in crystal-lined

crevices of Alpine granites and gneisses have been deposited,

with other minerals, from solution; the crystals lining veins

in the slates of Tintagel in Cornwall have the same origin.

Several varieties of albite are distinguished, of which

the following may be here specially mentioned. Pericline

(from the Gr. periklines, ``sloping'') is the name given

to large opaque white crystals from the chlorite-schists

of the Alps; they are tabular parallel to the direction of

perfect cleavage and are twinned according to the ``pericline

law.'' Peristerite (from the Gr. peristera, a dove) is

characterized by a beautiful bluish sheen, somewhat resembling

that seen on the neck of a pigeon; it is found mainly in

Ontario. Aventurine and moonstone varieties occur, though

these special appearances are more usually displayed by the

oligoclase and orthoclase felspars respectively. (L. J. S.)

'ALBO, JOSEPH, a Spanish Jewish theologian of the 15th

century. He was author of a very popular book on the philosophy

of Judaism, entitled `Iqqarim or Fundamentals. Maimonides

in the 12th century had formulated the principles of Judaism in

thirteen articles; Albo reduced them to three: (i) The Existence

of God, (ii) Revelation and (iii) Divine Retribution. Albo

set the example of minimizing Messianism in the formulation

of Jewish beliefs. Though he fully maintained the Mosaic

authorship of the Law and the binding force of tradition, he

discriminated between the essential and the non-essential in

the practices and beliefs of Judaism. An English translation

of the `Iqqarim appeared in the Hebrew Review, vols. i.-iii.

ALBOIN (d. 572 or 573), king of the Lombards, and conqueror

of Italy, succeeded his father Audoin about 565. The

Lombards were at that time dwelling in Noricum and Pannonia

(archduchy of Austria, Styria and Hungary, west of the

Danube). In alliance with the Avars, and Asiatic people

who had invaded central Europe, Alboin defeated the Gepidae,

a powerful nation on his eastern frontier, slew their king

Cunimund, whose skull he fashioned into a drinking-cup, and

whose daughter Rosamund he carried off and made his wife.

Three years later (in 568), on the alleged invitation of Narses

(q.v.), who was irritated by the treatment he had received

from the emperor Justin II., Alboin invaded Italy, probably

marching over the pass of the Predil. He overran Venetia and

the wide district which we now call Lombardy, meeting with

but feeble resistance till he came to the city of Ticinum

(Pavia), which for three years (569-572) kept the Lombards at

bay. While this siege was in progress Alboin was also engaged

in other parts of Italy, and at its close he was probably

master of Lombardy, Piedmont and Tuscany, as well as of the

regions which afterwards went by the name of the duchies

of Spoleto and Benevento. In 572 or 573, however, he was

assassinated by his chamberlain Peredeo at the instigation

of Queen Rosamund, whom Alboin had grievously insulted by

forcing her to drink wine out of her father's skull. After

his death and the short reign of his successor Cleph the

Lombards remained for more than ten years in a state of anarchy.

The authorities for the history of Alboin are Procopius, Paulus

Diaconus and Agnellus (in his history of the church of Ravenna).

ALBONI, MARIETTA (1823-1894), Italian opera-singer, was

born at Cesena, Romagna, and was trained in music at Bologna,

where she became a pupil of Rossini. She had a magnificent

contralto voice, and in 1843 made her first appearance

at La Scala, Milan, being recognized at once as a public

favourite. In England her reputation was established by her

appearance at Covent Garden in 1847, and she had brilliant

success all over Europe in the leading operatic roles;

in 1853 she repeated these triumphs in the United States.

Indeed, with the exception of Malibran, she had no compeer

among the contraltos of the century, the old Italian school

of singing finding in her a really great representative. She

married first Count A. Pepoh, who died in 1866, and secondly

(1877) a French officer, M. Zieger; she lived in Paris

after her first marriage, and died at Ville d'Avray in 1894.

ALBORNOZ, GIL ALVAREZ DE, Spanish cardinal, was born at

Cuenca early in the 14th Century. He was the son of Gil Alvarez

de Albornoz and of Dona Teresa de Luna, sister of Kimeno de

Luna, archbishop of Toledo. He was educated at Saragosa,

while his uncle was bishop of that see, and studied law at

Toulouse. The powerful influence of his family opened him

a public career early in life. He was made archdeacon of

Calatrava, and became a member of the king's council while

young. In 1337 he was chosen archbishop of Toledo in

succession to his uncle by the favour of the king, Alphonso

XI. At the battle of Tarifa he fought against a great invasion

from Africa in 1340, and at the taking of Algeciras in 1344

he led the armed levy of his archbishopric. In 1343 he

had been sent to Pope Clement VI. at Avignon to negotiate

a grant of a tax on the revenues of the Church for the

Crusade. His military and diplomatic ability became known

to the pope, who made him a cardinal in 1350. Albornoz left

Spain on the death of the king Alphonso XI. in that year, and

never returned. It has been said, but not on contemporary

evidence, that he fled from fear of Peter the Cruel. In 1353

Innocent VI. sent him as a legate into Italy, with a view to

the restoration of the papal authority in the states of the

Church. He was recalled in 1357, but was sent again to

Italy after a brief interval, and in 1362 had paved the way

for the return of Urban V. to Rome. As legate, Albornoz

showed himself to be an astute manager of men and effective

fighter. He began by making use of Rienzi, whose release

from prison at Avignon he secured. After the murder of

the tribune in 1354 Albornoz pursued his task of restoring

the pope's authority by intrigue and force with remarkable

success. As a mark of gratitude the pope appointed him

legate at Bologna in 1367, but he died at Viterbo the same

year. According to his own desire his remains were carried

to Toledo, where Henry of Castile caused them to be entombed

with almost royal honours. A work by Albornoz on the

constitution of the Church of Rome, first printed at Jesi in

1473, is now very rare. The college of St Clement at Bologna

was founded by Albornox for the benefit of Spanish students.

See ``De Vita et Rebus Gestis Aegidii Albornotii,'' in Sepulveda's

Opera Omnia, vol. iv. (1780); Cardenal Albornoz der zweite

Begrunder des Kirchenstaates, by Dr H. J. Wurm (1892).

ALBRECHTSBERGER, JOHANN GEORG (1736-1809), Austrian

musician, was born at Kloster-Neuburg, near Vienna, on the 3rd

of February 1736. He studied musical composition under the

court organist, Mann, and became one of the most learned and

skilful contrapuntists of his age. After being employed as

organist at Raab and Maria-Taferl, he was appointed in 1772

organist to the court of Vienna, and in 1792 Kapellmeister

of St Stephen's cathedral. His fame as a theorist attracted

to him in the Austrian capital a large number of pupils,

some of whom afterwards became eminent musicians. Among

these were Beethoven, Hummel, Moscheles and Josef Weigl

(1766-1846). Albrechtsberger died in Vienna on the 7th of March

1809. His published compositions consist of preludes, fugues

and sonatas for the piano and organ, string quartets, &c.; but

the greater proportion of his works, vocal and instrumental,

exists only in manuscript. They are in the library of the

Vienna Gesellschaft der Musikfreunde. Probably the most

valuable service he rendered to music was in his theoretical

Works. In 1790 he published at Leipzig a treatise on composition,

of which a third edition appeared in 1821. A collection

of his writings on harmony, in three volumes, was published

under the care of his pupil Ignaz von Seyfried (1776-1841) in

1826. There is an English version of this published by

Novello in 1855. Beethoven knew his own needs when he put

himself under Albrechtsberger on finding that Haydn was not

thoroughly disposed for the trouble of training him; and

though Albrechtsberger could see nothing in him, and warned his

other pupils against ``that young man who would never turn out

anything in good style,'' he justified Beethoven's confidence.

ALBRET. The lordship (seigneurie) of Albret (Labrit,

Lebret), situated in the Landes, gave its name to one of

the most powerful feudal families of France in the middle

ages. Its members distinguished themselves in the local wars

of that apoch; and during the 14th century they espoused the

English cause for some time, afterwards transferring their

support to the side of France. Arnaud Amanieu, lord of

Albret, helped to take Guienne from the English. His son

Charles became constable of France, and was killed at the

battle of Agincourt in 1415. Alain the Great, lord of Albret

(d. 1522), wished to marry Anne of Brittany, and to that end

fought against Charles VIII.; but his hopes being defeated by

the betrothal of Anne to Maximilian of Austria, he surrendered

Nantes to the French in 1486. At that time the house of

Albret had attained considerable territorial importance, due

in great part to the liberal grants which it had obtained

from successive kings of France. John of Albret, son of

Alain, became king of Navarre by his marriage with Catherine of

Foix. Their son Henry, king of Navarre, was created duke

of Albret and peer of France in 1550. By his wife Margaret,

sister of the French king, Francis I., he had a daughter, Jeanne

d'Albret, queen of Navarre, who married Anthony de Bourbon,

duke of Vendome, and became the mother of Henry IV., king of

France. The dukedom of Albret, united to the crown of France

by the accession of this prince, was granted to the family of

La Tour d'Auvergne in 1651, in exchange for Sedan and Raucourt.

To a younger branch of this house belonged Jean d'Albret,

seigneur of Orval, count of Dreux and of Rethel, governor

of Champagne (d. 1524), who was employed by Francis I.

in many diplomatic negotiations, more particularly in his

intrigues to get himself elected emperor in 1519. (M. P.*)

ALBRIGHT, JACOB (1759-1808), American clergyman, was

born near Pottstown, Pennsylvania, on the 1st of May

1759. He was of ``Pennsylvania-German'' parentage, his name

being originally Albrecht, and was educated in the Lutheran

faith. At an early age he became a tile-burner. In 1790

he was converted to Methodism, and in 1796 determined to

devote himself to preaching that faith among the Pennsylvania

Germans. His efforts met with great success, and in 1800

he founded what was virtually a new and independent church

organization on the Methodist system, of which he became

the presiding elder, and eventually (1807) bishop. This

church is officially the Evangelical Association, but its

adherents have been variously known as ``New Methodists.''

``Albrights,'' and ``Albright Brethren.'' Albright died

on the 18th of May 1808, at Muhlbach, Pennsylvania.

ALBUERA, or ALBUHERA, LA, a small village of Spain,

in the province of Badajoz, 13 m. S.E. of the town of that

name. Pop. (1900) 820. Albuera is celebrated on account of the

victory gained there on the 16th of May 1811 by the British,

Portuguese and Spaniards, under Marshal Beresford, over the

French army commanded by Marshal Soult. (See PENINSULAR WAR.)

ALBUFERA DE VALENCIA, a lagoon, 7 m. S. of Valencia in

Spain, about 12 m. in length and 4 in breadth, 12 ft. being

its greatest depth. It communicates with the sea by a narrow

outlet, which can be opened or closed at pleasure. The lake

is crown property, and is of great value from the fish and

wild-fowl with which it abounds. Rice is grown in large

quantities by the inhabitants of the adjoining villages. In

1812 Marshal Suchet was created duke of Albufera by Napoleon

for his conquest of Valencia, and invested with the domain; but

the battle of Vittoria in 1813 deprived him of his possession,

though he still retained the title. Subsequently the revenues

of Albufera were conferred upon the duke of Wellington in token

of the gratitude of the Spanish nation. (See PENINSULAR WAR.)

ALBULAE AQUAE, a group of springs, 4 m. W. of Tibur, the

water of which is bluish, strongly impregnated with sulphur and

carbonate of lime, and rises at a temperature of about 75 deg. F.

Remains of a Roman thermal establishment exist near the principal

spring, the so-called Lago della Regina (which is continually

diminishing in size owing to the deposit left by the water),

and dedicatory inscriptions in honour of the waters have been

found. The baths are still frequented by the Romans, though

the modern establishment is about 1 m. S. on the high road.

See T. Ashby in Papers of the British School at Rome, iii. 117.

ALBULA PASS, now the principal route from the N. to the Upper

Engadine in the Swiss Canton of the Grisons. It was already

frequented in the 13th century, while a carriage road (highest

point, 7595 ft.) was constructed across it in 1865, but for a

long time it was not as much used as the easier and more direct

Julier Pass (7504 ft.), until the opening of the railway in

1903, which has vastly increased its practical importance.

Starting from Coire the Rhine valley is followed to Reichenau

(6 1/4 m.), and then that of the Hinter Rhine to Thusis (10 1/2

m.). The line then runs through the grand Schyn gorge (cut by

the Albula torrent) to Tiefenkastell (7 1/2 m.), where it leaves

the Julier road on the right (S.) and continues to follow the

course of the Albula past Filisur and Bergun (12 1/2 m.) to

the mouth (5879 ft.) of the great tunnel (3 3/4 m. in length;

highest point, 5987 ft.) which has been pierced below the

pass. The descent lies through the Bevers glen to Bevers (2 1/2

m.), where the Upper Engadine is reached, about 5 m. below St.

Moritz, which is 56 m. from Coire by this route. (W. A. B. C.)

ALBUM (Lat. albus, white), in ancient Rome, a board

chalked or painted white, on which decrees, edicts and other

public notices were inscribed in black. The Annales Maximi

of the Pontifex Maximus, the annual edicts of the praetor,

the lists of Roman and municipal senators (decuriones) and

jurors (album indicum) were exhibited in this manner. In

medieval and modern times album denotes a book of blank

pages in which verses, autographs, sketches, photographs

and the like are collected. It is also applied to the

official list of matriculated students in a university, and

to the roll in which a bishop inscribes the names of his

clergy. In law, the word is the equivalent of mailles

blanches, for rent paid in silver (``white'') money.

ALBUMAZAR, more properly ABU-MAASCHAR (805-885), Arab

astronomer, was born at Balkh, flourished at Bagdad,

and died at Wasid in Central Asia. His principal works

are: De Magnis Conjunctionibus (Augsburg, 1489);

Introductorium in Astronomiam (Venice, 1506); and

Flores Astrologici (Augsburg, 1488). He maintained in the

first that the world, created when the seven planets were

in conjunction in the first degree of Aries, will come to

an end at a like conjunction in the last degree of Pisces.

ALBUMIN, or ALBUMEN (Lat. albus, white), an organic

substance typical of a group of bodies (albumins or

albuminates) of very complicated chemical composition. They

are sometimes called the histogenetic bodies or proteids,

because they are essential to the building up of the animal

organism. The vegetable kingdom is the original source of

albuminous substances, the albumins being found in greatest

quantity in the seed. They also occur in the fluids of the

living organism. The chemistry of the albumins is one of

the most complicated and difficult in the whole domain of

organic chemistry. It has attracted the attention of many

workers, and has formed the subject of a huge literature.

In this field Bechamp, Cohnheim, Albrecht Kossel, and,

especially, Emil Fischer and his pupils have been extremely

active. The general trend of these researches lies in the

study of the decomposition or ``breaking down'' products of

the albumin molecules; once these are accurately determined,

the synthesis of an albumin is but a matter of time. Already

we have proceeded far in our knowledge of the decomposition

products, and certain simple proteids have been synthesized.

General characters.

The albumins contain in all cases the elements carbon, hydrogen,

nitrogen, sulphur and oxygen; their composition, however,

varies within certain limits: C = 50-55%, H = 6.9-7.3%, N. =

15-19%, S = 0.3-2.4%, O = 19-24%, crystallized albumin is C =

51.48%, H = 6.76%, N = 8.14%, S = 0.96%, O = 22.66%, which

points to the formula C720H1134N218S5O248,

corresponding to the molecular weight 16,954. A high molecular

weight characterizes these substances, but so far no definite

value has been determined by either physical or chemical means;

A. P. Sabanezhev obtained the value 15,000 by Raoult's method

for purified egg albumin. All albumins are laevo-rotatory; and

on incineration a small amount of inorganic ash is invariably

left. They are usually insoluble in water, alcohol and ether;

and their presence as solutes in vegetable and animal fluids

is not yet perfectly understood, but it is probably to be

connected with the presence of salts or other substances. A

remarkable change occurs when many albumins are boiled with

water, or treated with certain acids, their solubility and

general characters being entirely altered, and the fluid becoming

coagulated. This change is seen in the transformation of the

``white'' of an egg on boiling. Albumins are generally detected

by taking advantage of this property, or of certain colour

changes. The reagents in common use are: Millon's reagent,

a solution of mercuric nitrate containing nitrous acid, this

gives a violet-red coloration; nitric acid, which gives a

yellow colour, turning to gold when treated with ammonia

(xanthoproteic reaction); fuming sulphuric acid, which gives

violet solutions; and caustic potash and copper sulphate, which,

on warming, gives a red to violet coloration (biuret reaction).

Decomposition products.

Boiling with dilute mineral acids, or baryta water, decomposes

albumins into carbon dioxide, ammonia and fatty amino- and other

acids. These decomposition products include: glycocoll or

aminoacetic acid, NH2CH2COOH, alanine or aminopropionic

acid, CH3.CH(NH2).COOH, a-aminobutyric acid,

a-aminovalerianic acid, leucin or isobutyl-a-aminoacetic

acid, (CH3)2CH.CH2.CH(NH2).COOH, isoleucin, probably

b-aminocaproic acid, serin or a-amino- b-hydroxypropionic

acid, HO.CH2.CH(NH2).COOH, aspartic acid or aminosuccinic

acid, HOOC.CH2.CH(NH2).COOH, glutaminic acid or a-amino-

n-glutaric acid, HOOC.(CH2)2.CH(NH2).COOH, diaminoacetic acid,

a-b-diaminopropionic acid, lysin. or a-e-diamino-n-caproic

acid, NH2(CH2)4.CH(NH2).COOH, arginin or guanidine-a-amino-

n-valerianic acid, (NH)(NH2)C.NH.(CH2)3.CH(NH2).COOH,

ornithin or ad-diamino valerianic acid,

NH2.(CH2)3.CH(NH2).COOH, histidin or a-amino- b-imidazol-

hydroxyproline, phenyl alanine or phenyl-a-aminopropionic

acid, C6H5.CH2.CH(NH2).COOH, tyrosine or p-hydroxyphenyl-

a- aminopropionic acid, phenyl ethylamine, p-hydroxyphenyl

``disulphide,'' (NH2.CH2.CH:S.COOH)2. This list is

not exhaustive; other products are given in Gustav Mann,

Chemistry of the Proteids (1906), to which reference should

be made for a complete account of this class of compounds.

Classification of albumins.

The complexity of composition militates in a great measure

against a rational classification of albumins by purely chemical

considerations. Such classifications have been attempted by

A. Kossel and by W. Kuhne and E. P. Pick; but in the present

state of our knowledge, however, the older classification

of E. Dreschel and F. Hoppe- Seyler, based primarily on

solubilities and distribution, may be conveniently retained.

This classification is with certain modifications as follows:-

I. Albumins proper: characterized by having colloidal solutions.

(1) Albumins: serum-albumin, egg-albumin, albumin.

(2) Globulins: serum-globulin, egg-globulin, lacto-

globulin, cell-globulins.

(3) Plant-globulins and plant-vitellines.

(4) Fibrinogen.

(5) Myosin.

(6) Phosphorus containing albumins (nucleo-albumins),

caseins, vitellines, nucleo-albumins of the cell-

protoplasm, mucoid nucleo-albumins.

(7) Histones.

(8) Protamines.

II. Transformation products of the albumins proper.

(1) Acid-albumins, alkali albuminates.

(2) Albumoses, peptones and peptides.

(3) Halogen-albumins, oxyprotein, oxyprotsulphonic

acid, &c.

III. Proteids.

(1) Nucleo-proteids.

(2) Haemoglobin and allied substances.

(3) Glyco-proteids, mucins, mucoids, helico-proteid.

IV. Albuminoids.

(1) Collagen.

(2) Keratin.

(3) Elastin.

(4) Fibroin.

(5) Spongin, &c.

(6) Amyloid.

(7) Albumoid.

(8) Colouring matters derived from albumin.

Albumins proper.--Albumins (as classified above) are

soluble in water, dilute acids and alkalies, and in

saturated neutral salt solutions; they are coagulated by

heat. ``Serum- albumin,'' or ``blood-albumin,'' possibly

C450H720N116S6O140, occurs in blood-serum,

lymph, chyle, milk, &c.; its coagulation temperature is about

67 deg. . It differs from egg-albumin in its specific rotation

(-57 deg. to -64 deg. ), and in being slowly coagulated by alcohol and

ether. Egg-albumin is the chief constituent of the white

of egg; this fluid also contains a globulin and a mucoid.

It coagulates at about 56 deg. , and its specific rotation is

-30.70 deg. . ``Lact-albumin'' occurs in all kinds of milk.

The globulins are insoluble in water and in dilute acids,

but soluble in alkalies and in neutral salt solutions; these

solutions are coagulated on boiling. ``Serum-globulin,'' also

termed globulin or fibrino-plastic globulin, paraglobulin and

paraglobin, occurs in blood serum; ``cell-globulins'' occur

in many organs--liver, kidneys, pancreas and the thyroid

gland, also in muscle-plasma; ``crystalline,'' a globulin

occurring in two forms a and b, is found in the lens

of the eye; ``egg-globulin'' and ``lacto- globulin'' occur

respectively in the white of egg and in milk. Plant albumins

or phyto-albumins have been chiefly investigated in the case

of those occurring in seeds; most are globulins, insoluble

in pure water, but soluble in salt solutions; ``edestin,''

a globulin of this class, is very widely distributed. Other

varieties or classes of these compounds are: plant caseins,

phyto-vitellines, legumins and conglutins. Fibrinogen

occurs in the blood plasma, and is changed by a ferment into

fibrin, to which the clotting of blood is due. Fibrinogen

is insoluble in water, but soluble in salt solutions; it

has three different coagulation temperatures, 56 deg. , 67 deg. ,

75 deg. . Fibrin, produced from fibrinogen by a ferment, is

a jelly-like substance, coagulable by heat, alcohol, &c.

The muscle-albumins include ``myosin'' or paramyosinogen, a

globulin, which by coagulation induces rigor mortis, and

the closely related ``myosinogen'' or myogen; myoglobulin and

myoalbumin are also found in muscles. The nucleo-albumins

or phospho-globulins are insoluble in water and acids, but

soluble in alkalies, and have an acid reaction. ``Caseinogen''

(after W. D. Halliburton) is the chief albumin of milk;

its composition varies with the animal. It is insoluble in

water, while its salts are readily soluble. ``Eucasein'' is

the ammonium salt; ``nutrose'' and ``plasmon'' are sodium

salts. By the rennet ferment caseinogen is converted into

casein, a substance resembling caseinogen in being soluble

in water, but differing in having an insoluble calcium

salt. The formation of casein involves the curdling of

milk. Other phosphoglobulins are vitelline, found in the

yolk of hens' eggs, and ichthulin, found in the eggs of

fish. Histones are a class of albumins soluble in water

and acids, but essentially basic in character; hence they

are precipitated by alkalies. It is remarkable that many

histones are soluble in an excess of alkali. They do not

exist in a free state, but in combination with a ``prosthetic

group'' (after A. Kossel) they give rise to important cell

constituents--haemoglobin, nucleo-proteids, &c. ``Thymus histone''

occurs in the thymus gland; globin occurs in combination as

haemoglobin; other histones have been extracted from the red

blood corpuscles of the goose and the testes of fishes and

other animals. The protamines are a well-characterized

class of albumins found in the ripe spermatozoa of fishes.

Albumoses and Peptones.--The primary products of the dissociation

of albumins are the albumoses, characterized by not being

coagulable by heat, more soluble than the albumins, having a

far less complex composition, and capable of being ``salted

out'' by certain salts, and the peptones, similar to albumoses

but not capable of being ``salted out''; moreover, peptones

are less complex than albumoses. By further decomposition

peptones yield peptides, a certain number of which have been

synthesized by Emil Fischer and his collaborators. Albumoses

and peptones are white powders, readily soluble in water, with

the exception of the hetero-albumoses--a subdivision of primary

albumoses. They give the biuret and xanthoproteic reactions,

and form salts with both acids and bases. Albumoses and

peptones are obtained by peptic digestion, the latter being

termed peptic- peptones; tryptic digestion also produces

peptones. Acids and moist heat induce similar changes.

Proteids.--These substances are combinations of one or more

albumins with a radical of an essentially different nature,

termed by Kossel a ``prosthetic group.'' It is convenient

to classify proteids by those groups. ``Nucleo-proteids,''

constituents of the cell-nucleus, are combinations of albumins

and nucleic acid; they always contain iron. They are loose,

white, non-hygroscopic powders, soluble in water and salt

solutions, and have an acid reaction; they give the colour

reactions of albumins. Nucleic acid is at present of unknown

constitution; decomposition products are: phosphoric acid, uracil

or 2.6-dioxy-pyrimidin,1 cytosin or 2-oxy-6-amino-pyrimidin,

thymin (nucleosin) or 2.6-dioxy-5-methyl pyrimidin hypoxanthin1

or 6-oxypurin, xanthin or 2.6-dioxypurin, adenine or 6

amino-purin, guanine or 2-amino-6-oxypurin, pentoses

(l-xylose), laevulinic acid, ammonia, etc. The nucleic acids

vary with the source of the proteids, there being considerable

differences in chemical composition. In general they are

white, loose powders, slightly soluble in cold water, more

soluble in hot water; they are precipitated by mineral acids,

but dissolve in an excess. They are dextrorotatory, and

the specific rotation is numerically greater than that of

albumin; hence the proteids are, in general, dextrorotatory.

An important nucleo-proteid is haemoglobulin or haemoglobin,

the colouring matter of the red blood corpuscles of vertebrates;

a related substance, haemocyanin, in which the iron of

haemoglobin is replaced by copper, occurs in the blood of

cephalopods and crayfish. Haemoglobin is composed of a

basic albumin and an acid substance haematin; it combines

readily with oxygen, carbon dioxide and carbon monoxide to

form loose compounds (see NUTRITION.) It coagulates at

64 deg. . By a dilute acid haemoglobin is decomposed into

globin, and ``haematin,'' a ferri-pyrrol derivative of the

probable formula C34H34N4FeO5; under certain conditions

the iron-free ``haematoporphyrin'' is obtained. This last

substance may be reduced to mesoporphyrin, C34H38O4N4,

which by further reduction gives haemo-pyrrol, C8H13N,

possibly methyl-propyl-pyrrol or butyl-pyrrol. Other

derivatives are haemin, haemochromogen and the haematinic acids.

``Glyco-proteids'' differ from nucleo-proteids in containing

a carbohydrate radical, which is liberated only by boiling

with mineral acids or alkalies. The mucins and mucoids belong

to this group; they are acid and contain no phosphorus; they

give the albumin colour reactions but are not coagulated by

heat. Mucins occur in most of the slimy fluids of the body; they

vary in composition with their source. Mucoids resemble mucins

in their composition and reactions, but differ, in general, in

their physical properties. They occur in tendons, bones and

cartilage. The ``phospho-glyco-proteids'' resemble the mucins

and mucoids in containing a carbohydrate residue, but differ

in containing phosphorus. Ichthulin (see above) maybe placed

in this group; ``helico-proteid,'' found in the serous gland

of Helix pomatia, the vineyard snail, also belongs here.

Albuminoids is the anatomical name given to albuminous

substances forming the connective tissues. Chemically they

resemble the albumins, being split up by acids or ferments

into albumoses, peptones and amino-acids, forming salts, and

giving the same colour reactions. They are quite insoluble

in water and in salt solutions, and difficultly soluble

in dilute acids and alkalies. Typical albuminoids are

gelatin, keratin, elastin, fibroin, spongin and conchiolin.

``Collagen'' (Gr. kolla, glue, and root gen- of gennaein,

to produce, gignesthai, to become), the ground-substance

of bones and tissues, is decomposed by boiling water or on

warming with acids into substances named gelatin, glutin or

glue. Gelatin forms a white amorphous powder; the commercial

product, however, generally forms glassy plates. The

decomposition products are generally the same as with the

general albumin; it gives the biuret reaction; forms salts

with acids and alkalies, but is essentially acid in nature.

Immersed in cold water gelatin does not dissolve but swells

up; it dissolves readily in hot water, forming, according to

the quantity present, a thick jelly which solidifies to a hard

mass on cooling (the ``glue'' of the wood- worker), or a thin

jelly (used in cookery). Gelatin occurs also in the cornea

and the sclerotic coat of the eye; and in fish scales, the

latter containing 80% of collagen, and 20% of ichthylepidin,

a substance differing from gelatin in giving a well-marked

Millon's reaction. Keratin (Gr. keras, a horn), the chief

constituent of horny material, occurs in hair, nails, hoofs and

feathers. It is quite insoluble in water, dilute acids and

alkalies. Related to this substance are ``neuro-keratin,''

found in the medullary sheath of nerves, and ``gorgonin,''

the matrix of the axial skeleton of the coral Gorgonia

Cavolinii. Elastin occurs either as thick strands or as

membranes; it constitutes the ``elastic tissue'' of the

anatomist. Its insolubility is much the same as keratin.

``Fibroin'' and silk-glue or sericin occur in natural silk

fibres. Fibroin is insoluble in water, acids and alkanes;

silk-glue resembles gelatin in its solubility, but it is less

readily gelatinized. ``Spongin,'' the matrix of bath-sponge, is

insoluble in water and dilute acids, but soluble in concentrated

mineral acids. ``Conchiolin,'' the matrix of shells of the

mollusca, is only slightly soluble in acids. ``Cornein'' forms

the framework of corals. ``Amyloid'' occurs as a pathological

product, and also in the healthy aorta and in old cartilage.

It is an albumin, and not a carbohydrate as was formerly held;

and gives most of the colour reactions of albumins. It forms

shiny, homogeneous masses, quite insoluble in cold water and

in salt solutions, but soluble in alkalies. The albumoids

include, according to Cohnheim, substances which possess

certain properties in common, but differ from the preceding

groups. In general they resemble coagulated albumin, and also the

gelatin-yielding tissues, but they themselves do not yield gelatin.

Colouring matters derived from albumins include the

``melanins'' (Gr. melas, black), substances which differ

very considerably in composition, the sulphur and iron

content being by no means constant; they do not give the

reactions of albumins. The black colouring matter of hair,

the skin of negroes, and of the ink bag of Sepia have been

examined. Melanins obtained from tumours form black,

shiny masses; they are insoluble in water, neutral salt

solutions, dilute acids and in the common organic solvents.

ALBUMINURIA (Physiological or Functional), a term indicating

the presence of albumin in the urine. This may depend on

a number of morbid conditions, of which kidney troubles,

acute illnesses and venous congestion are some of the

commoner. But after exclusion of all known pathological

causes, there still remains a large class of cases among

subjects who appear to be in perfect health. This form

has been called functional or physiological albuminuria,

intermittent albuminuria, &c. Its recognition is of extreme

importance, as it must be distinguished from the albuminuria

due to Bright's disease and other troubles. The following

are the main forms that have been described:--(1) Dietetic

Albuminuria. This form affects some people after partaking

of a meal consisting largely of albuminous foods, such as

eggs. In others any extra indulgence in the pleasures of the

table may give rise to it. (2) Cyclic Albuminuria. This name

was first used by the physiologist Pavy, but other observers

have called the same condition ``postural albuminuria.'' It

occurs in people enjoying perfect health, and is characterized

by the presence of albumin in the urine at certain times of the

day. It has been shown to depend entirely on the assumption

of the erect position, and it disappears as a result of

the recumbent position at night. (3) Albuminuria from

exercise. This form affects some people after any unusual

muscular exertion. (4) Prolonged mental strain or worry may

give rise to a transient form of albuminuria. (5) Adolescent

albuminuria is met with in some subjects, especially boys.

The question of the real significance of ``physiological''

albuminuria is one about which there is much difference of

opinion. But its importance and recognition--especially

in questions of life insurance--admits of no question.

ALBUQUERQUE, ALPHONSO D, (in Old Port. AFFONSO

D'ALBOQUERQUE) (1453-1515), surnamed THE GREAT, and

THE PORTUGUESE MARS, was born in 1453 at Alexandria, near

Lisbon. Through his father, Gonzalvo, who held an important

position at court, he was connected by illegitimate descent

with the royal family of Portugal. He was educated at the

court of Alphonso V., and after the death of that monarch

seems to have served for some time in Africa. On his return

he was appointed estribeiro-mor (chief equerry) to John

II. In 1503 he set out on his first expedition to the East,

which was to be the scene of his future triumphs. In company

with his kinsman Francisco he sailed round the Cape of Good

Hope to India, and succeeded in establishing the king of

Cochin securely on his throne, obtaining in return for this

service permission to build a Portuguese fort at Cochin, and

thus laying the foundation of his country's empire in the

East. He returned home in July 1504, and was well received

by King Emmanuel, who entrusted him with the command of a

squadron of five vessels in the fleet of sixteen which sailed

for India in 1506 under Tristan da Cunha. After a series of

successful attacks on the Arab cities on the east coast of

Africa, Albuquerque separated from Da Cunha, and sailed with

his squadron against the island of Ormuz, in the Persian Gulf,

which was then one of the chief centres of commerce in the

East. He arrived on the 25th of September 1507, and soon

obtained possession of the island, though he was unable long

to maintain his position. With his squadron increased by

three vessels, he reached the Malabar coast at the close

of the year 1508, and immediately made known the commission

he had received from the king empowering him to supersede

the governor Francisco de Almeida. The latter, however,

refused to recognize Albuquerque's credentials and cast him

into prison, from which he was only released, after three

months' confinement, on the arrival of the grand-marshal of

Portugal with a large fleet. Almeida having returned home,

Albuquerque speedily showed the energy and determination of his

character. An unsuccessful attack upon Calicut in January

1510, in which the commander- in-chief received a severe

wound, was immediately followed by the investment and capture

of Goa. Albuquerque, finding himself unable to hold the town

on his first occupation, abandoned it in August, to return with

the reinforcements in November, when he obtained undisputed

possession. He next directed his forces against Malacca,

which he subdued after a severe struggle. He remained in

the town nearly a year in order to strengthen the position

of the Portuguese power. In 1512 he sailed for the coast of

Malabar. On the voyage a violent storm arose, Albuquerque's

vessel, the ``Flor de la Mar,'' which carried the treasure

he had amassed in his conquests, was wrecked, and he himself

barely escaped with his life. In September of the same year

he arrived at Goa, where he quickly suppressed a serious revolt

headed by Idalcan, and took such measures for the security

and peace of the town that it became the most flourishing of

the Portuguese settlements in India. Albuquerque had been for

some time under orders from the home government to undertake

an expedition to the Red Sea, in order to secure that channel

of communication exclusively to Portugal. He accordingly

laid siege to Aden in 1513, but was repulsed; and a voyage

into the Red Sea, the first ever made by a European fleet, led

to no substantial results. In order to destroy the power of

Egypt, he is said to have entertained the idea of diverting

the course of the Nile and so rendering the whole country

barren. His last warlike undertaking was a second attack upon

Ormuz in 1515. The island yielded to him without resistance,

and it remained in the possession of the Portuguese until

1622. Albuquerque's great career had a painful and ignominious

close. He had several enemies at the Portuguese court who

lost no opportunity of stirring up the jealousy of the king

against him, and his own injudicious and arbitrary conduct

on several occasions served their end only too well. On his

return from Ormuz, at the entrance of the harbour of Goa, he

met a vessel from Europe bearing despatches announcing that

he was superseded by his personal enemy Soarez. The blow was

too much for him and he died at sea on the 16th of December

1515. Before his death he wrote a letter to the king in

dignified and affecting terms, vindicating his conduct and

claiming for his son the honours and rewards that were justly

due to himself. His body was buried at Goa in the Church

of our Lady, and it is perhaps the most convincing proof

possible of the justice of his administration that, many years

after, Mussulmans and Hindus used to go to his tomb to invoke

protection against the injustice of his successors. The

king of Portugal was convinced too late of his fidelity, and

endeavoured to atone for the ingratitude with which he had

treated him by heaping honours upon his natural son Alfonso.

The latter published a selection from his father's papers under

the title Commentarios do Grande Affonso d'Alboquerque .

See the Cartas de Albuquerque, published by the Lisbon Academy

(vol. i., 1884); also Morse Stephens' Life of Albuquerque;

an article in the Bolitim of the Lisbon Geographical

Society (January to June 1902) on ``O antigo Imperialismo

portuguez, &c.,'' has especial reference to Albuquerque.

ALBUQUERQUE, a city and the county-seat of Bernalillo

county, New Mexico, U.S.A., situated in the central part of the

state, about 325 m. S. by W. of Denver, on the E. bank of

the Rio Grande, at an altitude of 4950 ft. Pop. (1890) 3785;

(1900) 6238 (956 foreign-born and 226 negroes); (1910 census)

11,020. In 1900 Albuquerque was the largest city in New

Mexico. It is the connecting point of two main lines of the

Atchison, Topeka & Santa Fe railway system. A short distance

E. of the city is the university of New Mexico, under state

control, founded in 1889 and opened in 1892; in 1908 it had

a college of letters and science, a school of engineering,

a school of education, a preparatory school and a commercial

school. Albuquerque is also the seat of the Harwood Industrial

School (Methodist) for Mexican girls, of the Menaul Mission

School (Presbyterian) for Mexican boys, and of a government

Indian training school (1881) for boys and girls. The

city has a public library. The excellent climate has given

Albuquerque and the surrounding country a reputation as a

health resort. The city is an important railway centre, has

extensive railway repair shops and stock-yards, and exports

large quantities of live-stock, hides and wool. The largest

industrial establishment is the American Lumber Company's

plant, including a saw-mill, a sash, door and blind factory

and a box factory. The timber used, chiefly white pine, is

obtained from the Zuni mountains. The city has also flour and

woollen mills, breweries and ice factories. The old Spanish

town of Albuquerque (pop. in 1900 about 1200) lies about 1

m. W. of the present city; it was founded in 1706, and was

named in honour of the duke of Albuquerque, viceroy of New

Spain from 1702 to 1710. During the Civil War it was occupied,

late in February 1862, by Confederate troops under General

Henry Hopkins Sibley (1816-1886), who soon afterwards advanced

with his main body into northern New Mexico. In his retreat

back into Texas he made a stand on the 8th of April 1862 at

Albuquerque, where during the whole day there was a fight

at long range and with few casualties against a detachment

of Union soldiers commanded by Colonel Edward R. S. Canby

(1819-1873). The modern city dates its origin from the

completion of the first railway to Albuquerque in 1880.

ALBURNUM (sapwood), the outermost and youngest part of the

wood of a tree, through which the sap rises. It is distinguished

from the harder inner and older wood, the duramen or heart-wood.

ALBURY, a town in Goulburn county, New South Wales, Australia,

386 m. by rail W.S.W. of Sydney. Pop. (1901) 5821. It stands

near the border of Victoria, on the right bank of the Murray

river, here crossed by two bridges, one built of wood carrying

a road, the other of iron bearing the railway. The Murray

is navigable for small steamers from this town to its mouth,

a distance of 1800 miles. Albury is the centre of a sheep-

rearing and agricultural district; grapes, cereals and tobacco

are largely grown, and the wine produced here is held in high

repute throughout Australia. The tree under which the first

explorers encamped here in November 1824 is still standing

in an enclosed space. Albury became a municipality in 1859.

ALCAEUS (ALKAIOS), Greek lyric poet, an older contemporary

of Sappho, was a native of Mytilene in Lesbos and flourished

about 600 B.C. His life was greatly mixed up with

the political disputes and internal feuds of his native

city. He belonged to one of the noble families, and sided

with his class against the ``tyrants'' who at that time set

themselves up in Mytilene. He was in consequence obliged to

leave his native country, and spent a considerable time in

exile. He is said to have become reconciled to Pittacus, the

ruler set up by the popular party, and to have returned to

Lesbos. The date of his death is unknown. The subjects of

his poems, which were composed in the Aeolic dialect, were

of various kinds: some were hymns to the gods; others were of

a martial or political character; others breathed an ardent

love of liberty and hatred of tyrants; lastly, some were

love-songs. Alcaeus was allotted the second place among the

nine lyric poets in the Alexandrian canon. The considerable

number of fragments extant, and the well-known imitations

of Horace, who regarded Alcaeus as his great model, enable

us to form a fair idea of the character of his poems. A

new fragment has recently been discovered, together with

some fragments of Sappho (Classical Review, May 1902).

Lyrik (1883-1884); Farnell, Greek Lyric Poets (1891).

ALCAICS, in ancient poetry, a name given to several kinds

of verse, from Alcaeus, their reputed inventor. The first

kind consists of five feet, viz. a spondee or iambic, an

iambic, a long syllable and two dactyles; the second of two

dactyles and two trochees. Besides these, which are called

dactylic Alcaics, there is another, simply styled Alcaic,

consisting of an epitrite, two choriambi and a bacchius; thus--

Cur timet fla|vum Tiberim | tangere, cur | olivum?

The Alcaic ode is composed of several strophes, each

consisting of four verses, the first two of which are always

eleven-syllable alcaics of the first kind; the third verse

is an iambic dimeter hypercatalectic consisting of nine

syllables; and the fourth verse is a ten-syllable alcaic

of the second kind. The following strophe is of this

species, which Horace calls Alcaei minaces camenae--

Non possidentem multa vocaveris

Recte beatum; rectius occupat

Nomen beati, qui deorum

Muneribus sapienter uti.

There is also a decasyllabic variety of the Alcaic metre.

The Alcaic measure was one of the most splendid inventions

of Greek metrical art. In its best examples it gives

an impression of wonderful vigour and spontaneity.

Tennyson has attempted to reproduce it in English in his

O mighty-mouthed inventor of harmonies,

O skilled to sing of time or eternity,

God-gifted organ-voice of England,

Milton, a name to resound for ages.

German is, however, the only modern literature in which alcaics

have been written with much success. They were introduced by

Klopstock, and used by Holderlin, by Voss in his translations

of Horace, by A. Kopisch and other modern German poets.

ALCALA (Moorish al Kala, the ``Fortress'' or ``Castle''),

the name of thirteen Spanish towns, all founded or named by the

Moors. Alcala de Henares (pop. (1900) 11,206) is separately

described on account of its historical importance. Alcala

la Real (15,973), a picturesque town with a fine abbey, is

situated in mountainous country in the extreme south-west of

Jaen. Its distinctive name la Real, ``the Royal,'' was

conferred in memory of its capture by Alphonso XI. of Leon in

1340. In 1810 the French under Count Sebastiani here defeated

the Spaniards. Alcala de los Gazules (8877), on the river

Barbate, in the province of Cadiz, has a thriving trade in

cork and agricultural produce. Alcala de Guadaira (8198),

on the river Guadaira, near Seville, is popularly called

Alcala de los Panadores, or ``Alcala of the Bakers,''

because it supplies Seville with large quantities of

bread. Alcala de Chisbert (6293) is situated on the coast

of Castellon de la Plana; Alcala del Rio (3006), on the

Guadalquivir, 6 m. N. of Seville; Alcala del Jucar (2968),

on the Jucar, in Albacete; Alcala de la Selva (1490), on

the southern slopes of the Sierra del Gudar, in Teruel;

Alcala de la Vega (712), on the river Cabriel, in Cuenca;

Alcala de Gurrea (632), on the river Seton, in Huesca;

Alcala del Obispo (432), in the same province; Alcala de

Ebro (388) and Alcala de Moncayo (367), both in Saragossa.

ALCALA DE HENARES, a town of Spain, in the province of

Madrid, 17 m. E.N.E. of Madrid, on the river Henares, and

the Madrid-Saragossa railway. Pop. (1900) 11,206. Alcala

de Henares contains a military academy and various public

institutions, but its commercial importance is slight and its

main interest is historical. The town has been identified

with the Roman Complutum, which was destroyed about the year

1000, and was rebuilt by the Moors in 1083. In later times

it was renowned for its richly endowed university, founded by

Cardinal Jimenes de Cisneros in 1510, which at the height of

its prosperity numbered 12,000 students, and was second only

to that of Salamanca. Here the famous edition of the Bible

known as the Complutensian Polyglot was prepared from 1514 to

1517. The college of San Ildefonso, completed in 1583, was

the chief university building. Its modernized Gothic church,

the Colegiata, contains the 16th century marble monument of

Jimenes (d. 1517) and a fine reredos. The greatest of Spanish

writers, Cervantes, was born at Alcala de Henares, and baptized

in the otherwise insignificant church of S. Maria on the 9th

of October 1547. A tablet, set up in 1840, marks the house

in which he is said to have been born. Other illustrious

natives of the town were the emperor Ferdinand I. (1503-1564)

and the Spanish dramatist and historian Antonio de Solis

(1610-1686). After the removal of the university to Madrid

in 1836 the town rapidly declined, and the government turned

most of the principal buildings erected by Cardinal Jimenes

in the 16th century into a depot for the archives of various

state departments. Here are kept very complete and curious

documents of the Inquisition, showing all its workings

from the 15th to the 19th century. One of the principal

libraries is the former palace of the archbishops of Toledo.

For a fuller description of Alcala see the Guia del viajero

en Alcala de Henares, by L. A. de la Torre (Alcala,

1882). The following works are mainly of historical

interest:--M. de Ayala and F. Sastre, Alcala de Henares

(Madrid, 1890); J. C. Garcia, Ensayo de una Tipografia

Complutense (Madrid, 1889); M. Portilla y Esquivel, Historia

de la ciudad de Compluto (Alcala, 1725-1728); and the

``Annales Complutenses'' and ``Chronicon Complutense'' in

Espana Sagrada, by H. Florez and others (Madrid, 1754-1879).

ALCALDE (from the Arab. al-quadi, the ``Cadi'' or

``judge,'), the title in Spanish for officials of somewhat

varied functions, in which, however, there is always a judicial

element. Alcalde de corte was a judge of the palace

court, having jurisdiction in and about the residence of the

king. But the mayor of a town or village who discharged the

functions of a justice of the peace was also an alcalde. It

is in this sense that the title is now exclusively used. He

is subject to yearly election and the post has often been an

undesirable one in Spain. The title of alcalde must be carefully

distinguished from alcaide, which is derived from the Arabic

al-quaid, a general, and means the governor of a fortress.

ALCAMENES, a Greek sculptor of Lemnos and Athens. He was

a younger contemporary of Pheidias and noted for the delicacy

and finish of his works, among which a Hephaestus and an

Aphrodite ``of the Gardens'' were conspicuous. Pausanias

says (v. 10. 8) that he was the author of one of the pediments

of the temple of Zeus at Olympia (see GREEK ART), but this

seems a chronological and stylistic impossibility. At Pergamum

there was discovered in 1903 a copy of the head of the Hermes

``Propylaeus'' of Alcamenes (Athenische Mittheilungen,

1904, p. 180). As, however, the deity is represented in

an archaistic and conventional character, this copy cannot

be relied on as giving us much information as to the usual

style of Alcamenes, who was almost certainly a progressive

and original artist. It is safer to judge him by the

sculptural decoration of the Parthenon, in which he must almost

certainly have taken a share under the direction of Pheidias.

ALCAMO, a town of Sicily, in the province of Trapani, 24

m. W.S.W. of Palermo direct (51 1/2 m. by rail). Pop. (1881)

37,497; (1901) 51,809. It was founded in A.D. 828 by the

Saracenic chief Al-Kamuk, who erected the castle (which still

stands, though considerably altered), but was christianized

by the emperor Frederick II. in 1233, who removed the

site lower down. It possesses some medieval buildings of

interest. The surrounding district is very fertile

and the trade in agricultural products is considerable.

ALCANTARA, a small seaport of Brazil, in the state of Maranhao,

on the W. shore of the bay of Sao Marcos, 16 m. from the city of

Maranhao by water. It has a fairly good harbour, and excellent

cotton and rice are grown in the vicinity and shipped thence.

ALCANTARA, a town of western Spain, in the province of

Caceres, situated on a rocky height on the left bank of the

river Tagus, 7 m. from the Portuguese frontier. Pop. (1900)

3248. Alcantara (in Arab. ``the bridge'') owes its name

to the magnificent Roman bridge which spans the Tagus on the

north-west. This was originally built about A.D. 105,

in honour of the Roman emperor Trajan and at the cost of

eleven Lusitanian communities. It is entirely constructed

of granite blocks, without cement, and consists of six

arches of various sizes, with a total length of 616 feet

and a height of about 190 ft. in the middle piers, which are

surmounted by a fortified gateway. One of the arches was

broken down in 1213 and rebuilt in 1553; another was blown

up by the British troops in 1809, and, though temporarily

reconstructed, was again destroyed in 1836, to prevent the

passage of the Carlist forces. But in 1860 the whole was

restored. A small Roman temple, dedicated to Trajan and

other deified emperors, stood on the left bank, adjoining the

bridge. It is doubtful, however, if Alcantara marks the

site of any Roman town, though archaeologists have sometimes

identified it either with Norba Caesarea or with Interamnium.

It first became famous about 1215 as the stronghold of the

knightly Order of Alcantara. Many of the grand masters of

this order lie buried in the 13th-century Gothic church.

The town possesses another interesting church built in 1506.

See Antiguedades y santos de la muy noble villa de Alcantara,

by J. Arias de Quintanaduenas (Madrid, 1661); and Retrato

politico de Alcantara, by L. Santibanez (Madrid, 1779).

ALCAVALA (Spanish, from Arab. al-quabalah, ``tax,''

quabula, ``to receive''; cf. Fr. gabelle), a duty

formerly charged in Spain and its colonies on all transfers

of property, whether public or private. Originally imposed

in 1341 by Alphonso XI. to secure freedom from the Moors,

it was an ad valorem tax of 10, increased afterwards to

14%, on the selling price of all commodities, whether raw

or manufactured, chargeable as often as they were sold or

exchanged. It subjected every farmer, manufacturer, merchant

and shopkeeper to the continual visits and examination

of the tax-gatherers, whose number was necessarily very

great. This monstrous impost was permitted to ruin the

industry and commerce of the greater part of the kingdom

up to the time of the invasion of Napoleon. Catalonia

and Aragon purchased from Philip V. an exemption from the

alcavala, and, though still burdened with other heavy taxes,

were in consequence in a comparatively flourishing state.

ALCAZAR DE SAN JUAN, or ALCAZAR, a town of Spain, in

the province of Ciudad Real, in the plain of La Mancha, at

the junction of the Madrid-Manzanares and Madrid-Albacete

railways. Pop. (1900) 11,499. Owing to its position on two

important railways, Alcazar has a flourishing transit-trade

in the wines of Estremadura and Andalusia; the soda and

alkali of La Mancha are used in the manufacture of soap; and

gunpowder, chocolate and inlaid daggers are also made here.

Alcazar is sometimes identified with the Roman Alce. captured

by Tiberius Sempronius Gracchus in 180 B.C. It derives its

existing name from its medieval Moorish castle (al-kasr),

which was afterwards garrisoned by the knights of St John.

The townsfolk contend that the great Cervantes was a native

of Alcazar; and, although this claim must be disallowed, much

of the action of his masterpiece, Don Quixote, takes place

in the neighbourhood. El Toboso, for instance, a village 12

m. E.N.E. [pop. ( 1900) 1895], was the home of the Lady

Dulcinea del Toboso; Argamasilla de Alba (3505), 22 m. S.E.,

is declared by tradition to be the birthplace of Don Quixote

himself. Local antiquaries even identify the knight with Don

Rodrigo de Pacheco, whose portrait adorns the parish church;

and the same authorities hold that part of the romance was

written while Cervantes was a prisoner in their town. An

edition of Don Quixote was published at Argamasilla in 1864.

ALCESTER, FREDERICK BEAUCHAMP PAGET SEYMOUR, BARON

(1821-1895), British admiral, son of Colonel Sir Horace

Beauchamp Seymour and cousin of Francis George Hugh Seymour,

5th marquess of Hertford, was born on the 12th of April

1821. Entering the navy in 1834, he served in the Mediterranean

and the Pacific, was for three years flag-lieutenant to his

uncle Sir George Seymour, and was promoted to be commander in

1847. He served in Burma as a volunteer in 1852, was made

a captain in 1854, took the ``Meteor'' ironclad battery out

to the Black Sea and home again in 1856, was captain of the

``Pelorus'' on the Australian station from 1857 to 1863,

and commanded the naval brigade in New Zealand during the

Maori War, 1860-61, for which he was made a C.B. He became

a rear-admiral in 1870; in 1871-1872 he commanded the flying

squadron, was a lord of the admiralty in 1872-1874, and

commanded the Channel fleet, 1874-1876. On the 31st of December

1876 he was made a vice-admiral, a K.C.B. on the 2nd of June

1877. In 1880-1883 he was commander-in-chief of the fleet

in the Mediterranean, and in 1880 had also the chief command

of the European squadron sent to the coast of Albania as

a demonstration to compel the Porte to cede Dulcigno to

Montenegro. On the 24th of May 1881 he was made a G.C.B.,

and on the 6th of May 1882 was promoted to the rank of

admiral. In July 1882 he commanded at the bombardment of

Alexandria and in the subsequent operations on the coast of

Egypt, for which service he was raised to the peerage as

Baron Alcester of Alcester in the county of Warwick, received

a parliamentary grant of L. 25,000, the freedom of the city

of London and a sword of honour. On his return from the

Mediterranean he was for a couple of years again at the

admiralty, and in 1886 he was placed on the retired list. For

the next nine years he lived chiefly in London, but latterly

his health was much broken, and he died on the 30th of March

1895. He was unmarried and the peerage became extinct.

ALCESTER [pronounced Auster, a market-town in the

Stratford-on-Avon parliamentary division of Warwickshire,

England, 16 m. W.S.W. from Warwick by the Great Western

railway, served also by the Birmingham-Evesham branch of

the Midland railway. Pop. (1901) 2303. It is pleasantly

situated among low wooded hills at the junction of the small

stream Alne with the Arrow, a northern tributary of the

Avon. The church of St Nicholas, with the exception of the

Decorated tower, is a reconstruction of 1734; among several

monuments is a fine example of Chantrey's work, to the 2nd

marquess of Hertford (d. 1822). There are a picturesque

town hall (1641), raised on stone columns, and a free grammar

school. The manufacture of needles is less important than

formerly, having been absorbed into the centre of the industry

at Redditch in the neighbouring county of Worcestershire. There

are implement works and cycle works, and brewing is prosecuted.

The name (Alnecestre, Alyncester) signifies ``the camp on the

Alne.'' A small Romano-British town or village was situated

here, on the road which runs from Derby and Wall, near Lichfield,

to join the Fosse Way near Cirencester. Its name is not

known. A relief figure in stone, some pavements, potsherds,

coins and burials have been found, but nothing to indicate an

important station. No written document relating to Alcester

exists before the reign of Henry I. No mention occurs in

Domesday, but it is given in a list of serjeanties of the

reign of Henry III. as having been a royal borough in the time

of Henry I., and in 1177 it rendered four marks' aid with the

other boroughs of the county. However, there is no evidence

of the grant of a royal charter, and the title of borough soon

lapsed. In the reign of Henry III. a moiety of the manor

was purchased by Sir Walter Beauchamp, who granted a charter

to the inhabitants of ihe town establishing a Tuesday market

for corn, cattle, and all kinds of merchandise, and also

obtained grants of fairs at the feasts of St Giles (afterwards

transferred to the feast of St Faith) and St Barnabas. In

1444 Sir John Beauchamp purchased the remaining moiety of the

manor, and was granted an additional fair at the feast of St

Dunstan. From this date the Beauchamps were lords of the

whole manor until it passed by female descent to the Grevilles

in the reign of Henry VIII. in 1140 a Benedictine monastery

was founded here by Falph Boteler of Oversley, and received

the name of the Church of Our Lady of the Isle, owing to its

insulation by a moat meeting the river Arrow. The monastery

was suppressed among the smaller houses in 1536. Traces of

the moat and the foundations are still to be seen in Priory

Close. The ancient fairs survived to the end of the 19th century.

in 1830 the needle-manufacture employed nearly a thousand hands.

ALCESTIS (ALKESTIS), in Greek legend the daughter of

Pelias and Anaxibia, and wife of Admetus, king of Pherae in

Thessaly. She consented to die in place of her husband,

and was afterwards rescued by Heracles. This beautiful

story of conjugal devotion forms the subject of the

Alcestis of Euripides, which furnished the basis of

Robert Browning's Balaustion's Adventure. Sophocles

also wrote an Alcestis, of which only fragments remain.

See Dissel, Der Mythos von Admetus und Alkestis, 1882.

ALCHEMY. In the narrow sense of the word, alchemy is the

pretended art of making gold and silver, or transmuting the

base metals into the noble ones. The idea of such transmutation

probably arose among the Alexandrian Greeks in the early

centuries of the Christian era; thence it passed to the

Arabs, by whom it was transmitted to western Europe, and its

realization was a leading aim of chemical workers down to the

time of Paracelsus and even later. But ``alchemy'' was something

more than a particularly vain and deluded manifestation of

the thirst for gold, as it is sometimes represented; in its

wider and truer significance it stands for the chemistry of

the middle ages. The idea of transmutation, in the country

of its origin, had a philosophical basis, and was linked

up with the Greek theories of matter there current; thus,

by supplying a central philosophical principle, it to some

extent unified and focussed chemical effort, which previously,

so far as it existed at all, had been expended on acquiring

empirical acquaintance with a mass of disconnected technical

processes. Alchemy in this sense is merely an early phase of

the development of systematic chemistry; in Liebig's words, it

was ``never at any time anything different from chemistry.''

Regarding the derivation of the word, there are two main views

which agree in holding that it has an Arabic descent, the

prefix al being the Arabic article. But according to one,

the second part of the word comes from the Greek chumeia,

pouring, infusion, used in connexion with the study of the

juices of plants, and thence extended to chemical manipulations

in general; this derivation accounts for the old-fashioned

spellings ``chymist'' and ``chymistry.'' The other view

traces it to khem or khame, hieroglyph khmi, which

denotes black earth as opposed to barren sand, and occurs in

Plutarch as chumeia; on this derivation alchemy is explained

as meaning the ``Egyptian art.'' The first occurrence of

the word is said to be in a treatise of Julius Firmicus, an

astrological writer of the 4th century, but the prefix al

there must be the addition of a later copyist. Among the

Alexandrian writers alchemy was designated as e tes chrusou

te kai argurou poieseos techne theia kai iera or

e episteme iera. In English, Piers Plowman (1362)

contains the phrase ``experimentis of alconomye,'' with

variants ``alkenemye'' and ``alknamye.'' The prefix al

begins to be dropped about the middle of the 16th century.

Origins of Alchemy.--Numerous legends cluster round the

origin of alchemy. According to one story, it was founded

by the Egyptian god Hermes (Thoth), the reputed inventor of

the arts and sciences, to whom, under the appellation Hermes

Trismegistus, Tertullian refers as the master of those who

occupy themselves with nature; after him later alchemists

called their work the ``hermetic art,'' and the seal of

Hermes, which they placed upon their vessels, is the origin

of the common phrase ``hermetically sealed.'' Another legend,

given by Zosimus of Panopolis, an alchemistical writer said

to date from the 3rd century, asserts that the fallen angels

taught the arts to the women they married (cf. Genesis vi.

2), their instruction being recorded in a book called

Chema. A similar story appears in the Book of Enoch,

and Tertullian has much to say about the wicked angels who

revealed to men the knowledge of gold and silver, of lustrous

stones, and of the power of herbs, and who introduced the

arts of astrology and magic upon the earth. Again, the

Arabic Kitab-al-Fihrist, written by al-Nadim towards the

end of the 10th century, says that the ``people who practise

alchemy, that is, who fabricate gold and silver from strange

metals, state that the first to speak of the science of the

work was Hermes the Wise, who was originally of Babylon, but

who established himself in Egypt after the dispersion of the

peoples from Babel.'' Another legend, also to be found in Arabic

sources, asserts that alchemy was revealed by God to Moses and

Aaron. But there is some evidence that, in accordance with

the strong and constant tradition among the alchemists, the

idea of transmutation did originate in Egypt with the Greeks of

Alexandria. In the Leiden museum there are a number of papyri

which were found in a tomb at Thebes, written probably in the

3rd century A.D., though their matter is older. Some are

in Greek and demotic, and one, of peculiar interest from the

chemical point of view, gives a number of receipts, in Greek,

for the manipulation of base metals to form alloys which simulate

gold and are intended to be used in the manufacture of imitation

jewellery. Possibly this is one of the books about gold

and silver of which Diocletian decreed the destruction about

A.D. 290--an act which Gibbon styles the first authentic

event in the history of alchemy (Decline and Fall, chap.

xiii.). The author of these receipts is not under any

delusion that he is transmuting metals; the MS. is merely

a workshop manual in which are described processes in daily

use for preparing metals for false jewellery, but it argues

considerable knowledge of methods of making alloys and colouring

metals. It has been suggested by M. P. E. Berthelot that

the workers in these processes, which were a monopoly of the

priestly caste and were kept strictly secret, though fully

aware that their products were not truly gold, were in time

led by their success in deceiving the public to deceive

themselves also, and to come to believe that they actually

had the power of making gold from substances which were not

gold. Philosophical sanction and explanation of this belief

was then found by bringing it into relation with the theory

of the prima materia, which was identical in all bodies

but received its actual form by the adjunction of qualities

expressed by the Aristotelian elements--earth, air, fire and

water. Some support for this view is gained from study

of the alchemistical writings of the period. Thus, in the

treatise known as Physica et Mystica and falsely ascribed

to Democritus (such false attributions are a constant feature

of the literature of alchemy), various receipts are given

for colouring and gilding metals, but the conception of

transmutation does not occur. This treatise was probably

composed at a date not very different from that of the Leiden

papyrus. Later, however, as in the Commentary on this

work written by Synesius to Dioscorus, priest of Serapis at

Alexandria, which probably dates from the end of the 4th

century, a changed attitude becomes apparent; the more

practical parts of the receipts are obscured or omitted,

and the processes for preparing alloys and colouring

metals, described in the older treatise, are by a mystical

interpretation represented as resulting in real transmutation.

But while there are thus some grounds for supposing that the

idea of transmutation grew out of the practical receipts of

Alexandrian Egypt, the alchemy which embraced it as a leading

principle was also strongly affected by Eastern influences

such as magic and astrology. The earliest Greek alchemistical

writings abound with references to Oriental authorities and

traditions. Thus the pseudo-Democritus, who was reputed the

author of the Physica et Mystica, which itself concludes

each of its receipts with a magical formula, was believed

to have travelled in Chaldaea, and to have had as his master

Ostanes1 the Mede, a name mentioned several times in the

Leiden papyrus, and often by early Christian writers such as

Tertullian, St Cyprian and St Augustine. The practices of

the Persian adepts also are appealed to in the writings of the

pseudo-Democritus, Zosimus and Synesius. The philosopher's

egg, as a symbol of creation, is both Egyptian and

Babylonian. In the Greek alchemists it appears as the symbol

at once of the art and of the universe, enclosing within

itself the four elements; and there is sometimes a play of

words between to on and to won. The conception of

man, the microcosm, containing in himself all the parts

of the universe or macrocosm, is also Babylonian, as again

probably is the famous identification of the metals with the

planets. Even in the Leiden papyrus the astronomical symbols

for the sun and moon are used to denote gold and silver, and

in the Meteorologica of Olympiodorus lead is attributed to

Saturn, iron to Mars, copper to Venus, tin to Hermes (Mercury)

and electrum to Jupiter. Similar systems of symbols, but

elaborated to include compounds, appear in Greek MSS. of

the 10th century, preserved in the library of St Mark's at

Venice. Subsequently electrum (an alloy of gold and silver)

disappeared as a specific metal, and tin was ascribed to Jupiter

instead, the sign of mercury becoming common to the metal and the

planet. Thus we read in Chaucer (Chanouns Yemannes Tale):--
