100 - 12 = 88% of proof spirit;

and--

2207·7 / 88 = 25·1 gal. (nearly).

That is, 25-1/10 gal. of such spirit would contain 100 lbs. of absolute

alcohol.

By removing the decimal point one place to the _right_, we have the equiv.

measure of 1000 lbs. By removing it one, two, or three places to the

_left_, we have it respectively for 10 lbs., 1 lb., and 1/10 lb.; from

which the equiv. for all other weights may be easily obtained.

By reversing the above operation, the measure of alcohol corresponding to

any given weight of spirit, at any strength, may also be easily found.

The weight of 1 gal. of absolute alcohol being 7·938 lbs.; that of 1 gal.

of proof spirit, 9·2 lbs,; and that of the 'alcohol' in 1 gal. of proof

spirit, 4·53 lbs.; the weight of any number of gallons or volumes of

either, and their equivalents, may be easily found. Thus:--

gallons of alc. × 7·938 = lbs. weight of alc.

" pf. sp. × 9·2 = lbs. w. of pf. spt.

and--

gallons of alc. × 16·121 = lbs. weight of pf. spt.

" pf. spt. × 4·53 = content in lbs. weight of alc.

In these cases a knowledge of the first four rules of decimal fractions is

necessary, or, at least, advantageous; as the Excise officers carry their

calculations to two figures of decimals, or 1/100ths. Their plan is to

reject the third decimal figure when less than 5; but to carry 1 to the

next figure on the left hand, when it exceeds 5. Thus, 5·432 is set down

as only 5·43; but 5·437 is written 5·44. In the delicate chemical

processes of the laboratory, even greater accuracy is observed.

Formerly, spirit was said to be 1 to 3, 1 to 4, &c., over-proof, by which

it was meant that 1 gal. of water added to 3 or 4 gals. of such spirit

would reduce it to 'proof.' On the other hand, 1 in 5, or 1 in 8,

under-proof, meant that the 5 or 8 gals., as the case might be, contained

1 gal. of water, and the remainder represented the quantity of 'proof

spirit.' This method of calculation has now long given way to the

'centigrade system,' which not only admits of greater accuracy, but is

quite as simple. It should be adopted by every spirit-dealer in England,

from being that which is employed by the Revenue officers, whose 'surveys'

it is absolutely necessary that the trader should understand, in order

that his own estimation of his stock and his business calculations should

correspond with theirs.

Several other methods of alcoholometry, besides those already noticed,

have been adopted at various times, but the majority of them possess so

little accuracy as to be quite inapplicable to the purposes of trade, and

of the laboratory. Thus, the strength was at one time estimated by what

was called the 'proof.' A little of the spirit was poured upon a small

quantity of gunpowder, contained in a spoon or saucer, so as just to

moisten it, and was then inflamed. If at the end of the combustion the

gunpowder took fire, the spirit was held to be 'above proof,' if it only

languidly fizzed away, or slowly burnt, the spirit was said to be 'proof,'

but if the gunpowder failed to ignite, the spirit was esteemed 'below

proof.' Hence arose the terms 'proof' and 'proof spirit,' which have since

been adopted by Act of Parliament. Another method was that of dropping oil

into the spirit; if the oil floated, the spirit was considered to be

'under proof,' if it sunk, it was rated as 'proof' or 'over-proof.' The

'gunpowder test' is quite fallacious; for, if a certain quantity of a

spirit is capable of firing the gunpowder, a little excess of a spirit 20%

or 25% stronger will often fail to do so, so much water being formed as to

prevent the ignition. The 'PREUVE D'HOLLAND' test, of the French, or the

'BEAD,' is still frequently employed by persons unacquainted with the use

of the hydrometer. It consists in shaking the spirit in a phial, and

observing the size, number, and duration of the bubbles or beads, as they

are called. The larger and more numerous these are, and the more rapidly

they break and disappear, the stronger the spirit is presumed to be. This

method is unreliable, as the presence of sugar or acid, even in minute

quantities, will sometimes give to a weak sample the appearance of one

many degrees stronger. LOVI'S BEADS are also often employed to ascertain

approximately the strength of spirit, when a hydrometer is not at hand.

The insufficiency of most of the methods of alcoholometry here referred

to, throws us back on the Revenue System (Sykes' hydrometer), or on the

specific gravity for unsweetened spirits. For sweetened spirits, as

cordials, wines, beers, &c., there are none of the tests which give such

accurate results as the distillation test, previously described as the

Revenue Method.

The spirituous liquors of commerce being sold by measure, and not by

weight, the methods of alcoholometry which give the results, per cent., by

volume, are those we have chiefly explained. In the laboratory, the method

by weight is that most generally employed in delicate processes and in

analyses. By weight, the per-centage of alcohol remains the same for all

temperatures, for the same sample; whilst by volume, the per-centage

varies with the temperature of the liquid. This variation explains the

cause of many of the sudden apparent decreases and increases, which occur

in large stocks of spirits. Persons purchasing spirits during very warm

weather, and paying for them according to their apparent quantity and

strength, lose considerably by selling the same spirit when the weather

becomes colder, without being conscious of such loss from the hydrometer.

The reason of this is obvious, for, whilst the relative proportions of the

alcohol to the water continue the same, the sp. gr. and the volume alter

with the temperature; the latter being increased by warmth, and decreased

by cold, in exact opposition to the former. Accuracy requires, in all

cases, that a spirituous liquor should be tested for its strength at the

temperature at which it was measured; and measured at the same temperature

at which its strength was determined.

A consideration of these facts has led some of the great houses to

introduce the system of weighing their spirits, instead of measuring them,

the weight of an imperial gallon at 60° Fahr. being taken as the standard

gallon. This is the method adopted by the Inland Revenue, at all

distilleries, for assessing the duty, and will be readily understood by

the following example:--

Cwts. qrs. lbs.

Gross weight of full cask = 13 2 27

Tare = 2 2 5

------------

Net weight of spirit = 11 0 22

or 1254 lbs. Let us suppose the hydrometer indication to be 43·0, the

weight per imperial gallon would be 8·903 lbs. (see Table VI), and 1254 ÷

8·903 = 140 gallons.

=ALCOHOL; EFFECTS OF ALCOHOLISM.= Without entering into the controversy as

to whether the moderate consumption of alcohol, or its total disuse, is

the more conducive to personal health and comfort--whether, as Dr Anstie

and others have asserted it acts, when prudently taken, as a food--or

whether, as other medical authorities contend, even its moderate use is a

disturbing factor in the human economy--there need be no qualification of

the assertion, that when the drinking of spirituous liquids of any kind is

indulged in to excess, the habit, if persisted in, must sooner or later

terminate in impaired health, serious disease, and premature death.

A powerful array of facts could be brought in support of this statement.

For instance, in NELSON'S statistics we find it mentioned that--

A temperate person's | An intemperate person's

chance of living is-- | chance of living is--

|

At 20 = 44·2 years. | At 20 = 15·6 years.

" 30 = 36·5 " | " 30 = 13·8 "

" 40 = 28·8 " | " 40 = 11·6 "

" 50 = 21·25 " | " 50 = 10·8 "

" 60 = 14·285 " | " 60 = 8·9 "

The average duration of life after the commencement of habits of

intemperance is--

Among mechanics, working and labouring men 18 years.

" traders, dealers, and merchants 17 "

" professional men and gentlemen 15 "

" females 14 "

Again, Dr Dickinson, writing "on the morbid effects of alcohol in persons

who trade in liquor," gave the results of an examination of 149 traders in

liquor, as compared with 149 persons of various trades. The general

results were diseases of the liver much more common in those who dealt in

alcoholic drinks. In the lungs tubercle affected sixty-one persons of the

alcoholic, forty-four of the non-alcoholic.

Tubercle in the brain, liver, kidneys, spleen, bowels, mesenteric glands,

and peritoneum were twice as common in the alcoholic as in the

non-alcoholic. The verdict, therefore, is unavoidable that alcohol (in

excess) engenders tubercle in the brain, inflammations, atrophy,

hæmorrhages; in the heart and vessels atheroma, hypertrophy, and other

affections, were all more common in the alcoholic than in the

non-alcoholic series. The evidence in kidney disease did not appear so

conclusive, but some forms of kidney disease appear to be increased. The

author sums up thus:--"Alcohol causes fatty infiltration and fibroid

encroachment; it engenders tubercle, encourages suppuration, and retards

healing; it produces untimely atheroma, invites hæmorrhage, and

anticipates age. The most constant fatty change, replacement by oil of the

material of epithelial cells and muscular fibres, though probably nearly

universal, is most noticeable in the liver, the heart, and the kidney."

Alcohol also seems to be the cause of special diseases, besides those more

common and generally known ones, delirium tremens, alcoholism, &c. Of

these we may mention one recorded by M. GALEZOWSKI, a peculiar affection

of the eyes, which the doctor found very prevalent during the siege of

Paris in 1870-1. In the five months of the siege fifty patients were

affected by it, whilst during the twelve months preceding the siege only

nineteen were to be found. Dr GALOWSKI ascribed the malady to the habit of

taking alcoholic drinks in the morning fasting. A peculiar kind of palsy

has also been referred to alcoholic poisoning.

The following table, compiled by Dr Joseph Williams, lends support to the

fact that an indulgence in alcohol is either the cause of insanity, or

that it tends to its increase:

Commenting on these figures, Mr Walter Blyth remarks, "There may be

another explanation of the fact that many mad people have been great

drinkers. A large proportion of those subject to insanity are driven by

their morbid minds to drink; so that it may be that insanity causes drink,

and not drink causes insanity."

Many medical writers who are no advocates for the total abandonment of

alcohol limit its consumption, in healthy people, to one or two fluid

ounces a day, in the form of wine, beer, or spirits and water; two fluid

ounces is, we believe, the quantity apportioned daily to every able-bodied

seaman in the Royal Navy. Any slight habitual departure from this

standard--even when the evidences of excess are not perceptible to

others--all authority, historical, pathological, and physiological (unless

it be given as a medicine), shows to be injurious. The researches of

Anstie, Parkes, and Count Wollowicz, appear to prove that any quantity of

alcohol exceeding an ounce and a half taken by an adult showed itself in

the urine, a circumstance which these writers look upon as tending to show

that the system has taken more alcohol than can be used in the body

itself. In slight doses the action of alcohol is to produce a sedative

effect upon the nerves, to redden slightly the lining membrane of the

stomach, and to stimulate the secretion of the gastric juice.

Thus, in small doses alcohol may, and doubtless does, promote appetite. In

excess, however, all these effects are turned to evil, and then ensue an

inflammatory condition of the stomach, compression of the gland ducts from

thickening of the tissue around them, excessive mucous secretion, and

great loss of appetite. When carried into the circulation it greatly

increases the force of the heart's action, and at the same time paralyses,

as it were, the restraining nervous supply to the arteries and small

vessels, so that they can no longer oppose themselves to the

blood-current, but dilate. This action in a small degree, occurring in

persons of a weak and languid circulation, is no doubt beneficial; on the

other hand, when in excess, it is most dangerous, and is a cause of the

greater part of the diseases of the heart and great vessels.

"There appears to be a slight fall of temperature with moderate doses of

alcohol, a very decided fall with excessive doses; the muscular and

nervous systems are transitorily stimulated, and may do more work when

small doses are given in cases of fatigue, but in other cases there is a

marked torpor of the nervous and a want of co-ordination of the muscular

system."--BLYTH.

Notwithstanding the researches of Percy, Strauch, Masing, Lallemand,

Duroy, Parkes, Dupré, Anstie, Thudichum, and others, there is still a

considerable divergence of opinion as to how alcohol is eliminated from

the body. By some of the authorities just named it is affirmed to be

eliminated as aldehyd, by others as carbonic acid; as to the latter, the

experiments of Dr E. Smith show that the carbonic acid is decreased when

brandy and gin are drunk, and increased by rum.

The only probable supposition, which facts support, tends to show that the

alcohol is turned into acetic acid in the body, some of which unites with

potash and other bases, and some is destroyed. All are pretty well agreed

that in the form of spirits alcohol as a food is valueless, but that in

the form of beer and wine it is possessed of a slight dietetic power,

naturally varying with the amount and nature of the different substances

held in solution in these beverages.

The imports of spirits into this country, in the seven years from 1850 to

1857, amounted to 70,740,980 gallons; whilst the imports in the seven

years following, viz. from 1857 to 1864, were 78,016,071 gallons, showing

an increase of 7,305,091 gallons. The population has, however, increased

in the time, and a deduction on that account, as well as correction on one

or two other heads, are required; still, that there is an increase is

indisputable.

As respects France, a considerable increase in the consumption of spirits

has taken place of late years, as the following table by M. Husson will

illustrate:

_The Mean Consumption of Spirits for each Inhabitant._

Litres. Litres.

From 1825 to 1830 8·96 yearly. ·024 daily.

" 1831 " 1835 8·74 " ·023 "

" 1836 " 1840 10·15 " ·026 "

" 1841 " 1845 11·14 " ·031 "

" 1846 " 1850 11·03 " ·030 "

" 1851 " 1854 14·25 " ·039 "

In the United States, during the period from 1807 to 1828, the average was

27 litres for every inhabitant, which is even greater than the highest of

the two sets of figures just quoted.

The demoralisation of the French army during the late Franco-Prussian war

has been also unanimously ascribed to the excessive consumption of

spirituous liquids.

The following results of an inquiry instituted in 1870 by the

Massachusetts Board of Health into the comparative sobriety of different

nations are gathered from an able paper which appeared in the 'Medical

Times and Gazette' of April 15th, 1872, by Dr Druitt, in which he dissects

and summarises the results in question. Dr Druitt writes:

"Highest in the scale of temperance come the Turks and Arabs; next the

Iberians, Levantines, Greeks, and Latin races; lower down the Japanese,

Scandinavians, Belgians, and the Irish Celt; lowest of all the so-called

Anglo-Saxon of either continent."

Professor Levi contributes to our knowledge on this subject by giving the

following statistics:--In 1860 the committals for drunkenness in England

and Wales were 88,000, and in 1870 134,000, an increase of 50 per cent.

In Manchester the increase from 1860 to 1870 was 375 per cent., or

computed according to the increase of population 35·3 per cent. In London

drunkenness is in the proportion of 5·43 per 1000, in Leeds 7·40, in

Manchester 31·13, and in Liverpool 42·82. It must, however, be remembered

that these figures are based on mere committals, which greatly depend on

the activity of the police, and the noisy or quiet character of the

drunkard.

We quote the following from Dr Blyth's work on 'Hygiene,' without,

however, attempting either to endorse or controvert what he says on the

subject.

"_Whether is Alcohol necessary or not._ All experience, both at home and

abroad, shows by facts that cannot be disputed that a person can do quite

as hard work without alcohol as with it; and probably as the limits

between moderation and excess are easily passed, and as the generality of

mankind, even without intending it, err on the latter side, the result is

that a comparison between total abstainers and even temperate men

generally terminates in favour of the former. It would appear that total

abstainers live longer, are better citizens, and can do more work than the

rest of mankind. The figures of the "United Kingdom Temperance and General

Provident Institution" go far to prove the above. This insurance society

is divided into two sections. One section consists of abstainers, the

other of persons selected as not known to be intemperate. The claims for

five years anticipated in the temperance section were £100,446, but the

actual claims were only £72,676. In the general section of the anticipated

claims were £196,352; the actual claims no less than £330,297. In war the

march of 2000 miles in his War of Independence by Cornwallis and his

troops (1783), the Maroon war of Jamaica, the 400 miles' march of an

English army across the Desert from Komer, on the Red Sea, a march of 1000

miles in the Kaffir war, experiences at sieges, in action, in hot,

temperate, and cold climates, where abstinence was either forced through

circumstances or followed, shows to every unprejudiced mind that soldiers

endure more fatigue, are healthier, and fight better, without stimulants

than with them; and this fact is endorsed by every commander of the

present day.

The excess and abuse of spirits, as before remarked, lost the French their

military prestige in the Franco-German war. In very hot and very cold

climates the Indian observers and the Arctic explorers all unite in

condemning its (that is, the use of alcohol) use in the slightest excess,

or even in moderate doses. It does not warm the body in cold climates, and

the reaction that follows the exciting of the circulation is followed by a

dangerous depression; whilst in hot it combines with the climate, and

quickly produces disease."

=ALCOHOLIC DRINKS, EFFECTS OF.= In addition to the serious injury to

health caused by an excessive or imprudent indulgence in spirituous

stimulants (see previous article), even a moderate and not injudicious use

of them may often be attended with very disagreeable consequences--a more

or less mild or modified form of poisoning, in fact--if the beverages

themselves are, as very frequently happens, contaminated, either

accidentally or intentionally, with certain objectionable ingredients.

These ingredients are described under the articles BEER, WINES, and the

various SPIRITS, such as GIN, BRANDY, ABSINTHE, &c. Of spirit drinking it

may be observed, that this dangerous practice is intensified by what is to

be feared is the too prevalent custom of taking them undiluted, or "neat,"

as it is termed. There is no doubt that they constitute the very worst

form of alcoholic drinks, and shorten the lives of those who indulge in

them to excess more summarily than any other intoxicating potion. The

greatest and most ineradicable drunkards are almost always found to be

spirit drinkers.

Liebig remarked that less bread was consumed in families where beer was

drunk, and there seems to be little doubt that the different species of

beer, including porter and ale, when pure and free from adulteration,

act, although in a small degree, as food. Probably there are some who will

agree with, whilst others will dissent from, Benjamin Franklin, who said

"there was more sustenance in a penny loaf than in a gallon of beer." The

starchy extractive matters of the beer no doubt perform the same function

in the animal economy that sugar does. It is well known that those who

drink freely of beer mostly become corpulent, as witness the portly forms

of draymen. The hop contained in the beer has doubtless tonic and

stomachic qualities. We can speak with less certainty about the free acids

contained in malt fluids. It is very certain that some people cannot drink

a glass of beer without experiencing rheumatic pains in the joints, which

effect is generally ascribed to the acidity of the beer; but which is

really supposed to be due to the decreased elimination of urea and

pulmonary carbonic acid from the system caused by the alcohol of the beer.

The heavy low-priced beers occasion drunkenness of a peculiarly violent

and savage kind, a fact which strongly favours the inference that this

form of intoxication is due to some toxic agent, used as an adulterant. Of

wines, the clarets and subacid wines are undoubtedly antiscorbutic in

properties, and light wines as beverages are preferable to the stronger.

Port, sherry, beer, stout, and ale are almost universally condemned in

cases where there is a tendency to gout. The light clarets and Rhine wines

are far more desirable beverages when this is the case, and the German

wines are said to be valuable drinks in many lithic affections. It seems

probable that the ethers and the vegetable salts, together with the sugar

contained in wines, perform the most important part in the human economy.

It has been proposed to introduce the red subacid wines as drinks for our

sailors, because of their antiscorbutic qualities. Some of the alcoholic

drinks prepared in India frequently cause temporary madness.

=ALCOHOLISM.= ALCOHOL; EFFECTS OF ALCOHOLISM.

=AL'COHOLS.= In _chemistry_, a term applied to compounds possessing a

composition, formulæ, and chemical properties similar to those of ordinary

alcohol. They form a series presenting an unmistakable symmetry, and

differ from one another by well-marked gradations, as shown below:--

&c., &c.

=Alcohols.= In _commerce_, pure spirits of a greater strength than about

58 o. p. (sp. gr. 8335), or containing more than about 85% by WEIGHT, or

90% by VOLUME, of pure alcohol, are commonly so called.

=ALCORNO'CO.= _Syn._ A.-BARK; ALCORNOQUE, Fr.; ALKORNOC, A.-RIND, Ger. The

bark of an unknown tree of South America. It is astringent and bitter, and

has been highly extolled as a specific in phthisis; but appears to possess

little medicinal virtue. The bark of the young branches of the cork tree

(_quercus suber_), used in tanning, is also sometimes called

alcornoco-bark; but possesses none of the characters of the former

article.

=AL'DECAY.= The galls on the leaves of _myrobalanus chebula_ (Gaertn.), a

forest-tree of Bengal. Equal to the best oak-galls.

=AL'DEHYD= (-h[=i]d). [_al_-(cohol)-_dehyd_ (rogenatus).] C_{2}H_{4}O.

Syn. HYDRATED OXIDE OF ACETYLE; HYDRATE OF OTHYLE*; HYDROXIDE OF O.*

Literally, dehydrogenated alcohol. In _chemistry_, a peculiar ethereal

liquid, first obtained in a pure form by Liebig, from alcohol. It is

produced under various circumstances, particularly during the destructive

distillation of certain organic matters, and in several processes of

oxidation. The following are the most convenient methods of preparing

it:--

_Prep._ 1. (Liebig.) Sulphuric acid, 3 parts; is diluted with water, 2

parts; and as soon as the mixture has cooled, alcohol of 80%, 2 parts, is

added; and, subsequently, peroxide of manganese (in fine powder), 3 parts.

The whole, after agitation, is then distilled at a very gentle heat, from

a spacious retort into a receiver surrounded with ice, the connection

between the two being perfectly air-tight. The process is continued until

frothing commences, or the distillate becomes acid which generally occurs

when about one third (3 parts) has passed over. The distillate is next

agitated in a retort, with about its own weight of fused chloride of

calcium, in powder; after which about one half only is drawn over at a

very gentle heat (85° to 90° Fahr.), by means of a water bath. This

rectification is repeated in a precisely similar way. The last distillate

is ANHYDROUS ALDEHYD only slightly contaminated with foreign matters.

2. (Liebig.) Aldehyd-ammonia, 2 parts, is dissolved in an equal weight of

distilled water; and, after being placed in a retort, sulphuric acid, 2 or

3 parts, previously diluted with rather more than its own weight of

distilled water, and allowed to cool, is added. The whole is now

distilled, by means of a water bath, into a receiver surrounded with ice,

or (preferably) a freezing-mixture, the temperature of the bath at first

being very low, and the operation being stopped as soon, or rather before

the water begins to boil. The distillate is then placed in a retort

connected with a well-cooled receiver, as before; and after all the joints

are made perfectly tight, powdered fused chloride of calcium, in weight

equal to that of the liquid in the retort, is added through the

tubulature. The heat produced by the hydration of the chloride causes the

distillation to commence, after which it is carried on, by means of a

water bath, at a temperature ranging from 80° to 82° Fahr. This

rectification being very carefully repeated, the last distillate is PURE

ANHYDROUS ALDEHYD.

_Prop., &c._ Limpid, colourless, ethereal, neutral, inflammable; mixes in

all proportions with alcohol, ether, and water; odour peculiar,

penetrating, and, when strong, exceedingly suffocating, the vapour, in

quantity, producing spasmodic contraction of the thorax; boils at 72°

Fahr. (70°--Ure, 5th ed.); sp. gr. ·790 at 60°, and ·800 at 32° Fahr.; sp.

gr. of vapour, 1·532; by exposure to air it is gradually converted into

acetic acid, and speedily so under the influence of platinum-black; heated

with caustic potash, a brown substance resembling resin (ALDEHYD-RESIN) is

formed; gently heated with protoxide of silver, or its solutions, metallic

silver is deposited on the inner surface of the vessel, in a uniform and

brilliant film, whilst ALDEHYDATE OF SILVER remains in solution; heated

with hydrocyanic acid it yields ALANINE. By age, even in close vessels, it

passes into one or more isomeric compounds (ELALDEHYDE; METALDEHYDE), with

change of properties. Aldehyde for experiments should, therefore, be

always recently prepared; and it must be kept in a well-stopped bottle, in

a very cold place, and preferably in ice.

_Obs._ Aldehyd is important for its assumed position in the acetyl-series,

and the part which it plays in the process of acetification, &c. The word

is now also commonly employed, by chemists, as a generic term for any

organic substance which, by assimilating two atoms of hydrogen, yields, or

would yield, a compound having the composition or properties of an

alcohol; or which, by taking up one atom of oxygen, yields an acid. Many

of the essential oils (as those of almonds, cinnamon, and cumin) are

composed principally of bodies which may thus be called aldehyds. One of

the most valuable properties of these substances, is their strong tendency

to combine with the bisulphites of ammonium, potassium, and sodium; and by

which they may be separated from complex mixtures.

=AL'DEHYD-AMMO'NIA= (-h[)i]d-). An ammonia-compound of aldehyd, discovered

by Döbereiner and Liebig.

_Prep._ (Liebig.) Aldehyd (of process No. 1, above) is mixed with an equal

volume of ether,[16] in a flask surrounded with ice, or (what is better) a

freezing-mixture; and is then saturated with dry gaseous ammonia. The

crystals which soon form, after being washed with ether, and dried by

means of bibulous paper and a short exposure to the air, are pure aldehyd

ammonia.

[Footnote 16: Some authorities recommend the use of twice this quantity of

ether.]

_Prop., &c._ It smells like a mixture of turpentine and ammonia; melts at

165° to 170°; volatilises, unchanged, at 212° Fahr.; decomposed by

exposure to the air; very soluble in water; soluble in alcohol, and more

or less so in most other menstrua, except ether; acids decompose it. With

sulphuretted hydrogen it forms thialdine.--_Use._ Chiefly to make pure

aldehyd (which _see_).

=AL'DER= (awl'-). _Syn._ AL'DER-TREE; AL'NUS ([)a]l-), L.; A. GLUTINO'SA

(Gaertn.); BETU'LA ALNUS, Linn.; AUNE, AULNE, Fr.; ERLE, Ger. A well-known

English tree, chiefly growing in moist grounds near rivers. Its wood is

used for hurdles, for various articles of turnery and furniture, and when

converted into charcoal, for making gunpowder; it possesses considerable

durability under water; but is otherwise of little value. Bark and leaves

very astringent, and reputed vulnerary; decoction used as a gargle in sore

throat, and, in double the dose of cinchona, as a febrifuge in agues; bark

and sap used in dyeing and tanning. The following belong to different nat.

orders and genera to the preceding:--

=Alder, Black.= _Syn._ WIN'TER-BERRY; PRI'NOS VERTICILLA'TUS, Linn. A tree

growing in the United States of America. Bark febrifuge, tonic, and

astringent; berries tonic and emetic. (Bigelow.) It has been much

recommended in dropsies, diarrh[oe]a, intermittents, &c. _Dose_ (of the

dried bark), 1/2 to 1 dr., 3 or 4 times a day.

=Alder-tree, Black.= _Syn._ BERRY-BEARING ALDER-TREE; RHAM'NUS FRAN'GULA,

Linn. A large shrub found in the woods and thickets of England, &c. Wood,

BLACK DOG'WOOD; bark, bitter, emetic, purgative; used to dye yellow;

root-bark, a drastic purgative; berries, purgative, emetic; unripe berries

yield SAP-GREEN; charcoal of the wood esteemed the best for gunpowder.

=ALE.= _Syn._ BARLEY WINE*; AILE, Fr.; WEISS-BIER, Ger.; AEL, EALE, Sax.;

CEREVIS'IA ALBA, C. LUPULA'TA, A'LA*, AL'LA*, L. Pale-coloured beer,

prepared from lightly dried malt, by the ordinary process of brewing. The

ale of the modern brewer is manufactured in several varieties, which are

determined by the wants of the consumer, and the particular market for

which it is intended. Thus, the finer kinds of Burton, East India,

Bavarian, and other like ales, having undergone a thorough fermentation,

contain only a small quantity of undecomposed sugar and gum, varying from

1 to 5 per cent. Some of these are highly 'hopped,' or 'bittered,' the

further to promote their preservation during transit and change of

temperature. Mild or sweet ales, on the contrary, are less attenuated by

lengthened fermentation, and abound in saccharine and gummy matter. They

are, therefore, more nutritious, though less intoxicating, than those

previously referred to.

In brewing the finer kinds of ale, pale malt and the best East Kent hops

of the current season's growth, are always employed; and when it is

desired to produce a liquor possessing little colour, very great attention

is paid to their selection. With the same object, the boiling is conducted

with more than the usual precautions, and the fermentation is carried on

at a somewhat lower temperature than that commonly allowed for other

varieties of beer. For ordinary ale, intended for immediate use, the malt

may be all pale; but, if the liquor be brewed for keeping, and in warm

weather, when a slight colour is not objectionable, one fifth, or even one

fourth of 'amber malt' may be advantageously employed. From 4-1/2 lbs. to

6 lbs. of hops is the quantity commonly used to the quarter of malt, for

'ordinary ales,' and 7 lbs. to 10 lbs. for 'keeping ales.' The

proportions, however, must greatly depend on the intended quality and

description of the brewing, and the period that will be allowed for its

maturation.

The stronger varieties of ale usually contain from 6 to 8% of 'absolute

alcohol,' ordinary strong ale, 4-1/2 to 6%; mild ale, 3 to 4%; and table

ale, 1% to 1-1/2%; (each by volume); together with some undecomposed

saccharine, gummy, and extractive matter, the bitter and narcotic

principles of the hop, some acetic acid formed by the oxidation of the

alcohol, and very small and variable quantities of mineral and saline

matter. For the adulterants of ale, see PORTER. See BEER, BREWING,

FERMENTATION, MALT-LIQUORS, &c.

=Ale, Dev'onshire White.= A liquor once generally drunk, and still in

demand, in the neighbourhood of Kingsbridge and Modbury, Devon.

_Prep._ Ordinary ale-wort (preferably pale) sufficient to produce 1

barrel, is slowly boiled with about 3 handfuls of hops, and 12 to 14 lbs.

of crushed groats, until the whole of the soluble matter of the latter is

extracted. The resulting liquor, after being run through a coarse

strainer, and become lukewarm, is fermented with 2 or 3 pints of yeast;

and, as soon as the fermentation is at its height, is either closely

bunged up for 'draught,' or is at once put into strong stoneware bottles,

which are then well corked and wired.

_Obs._ White ale is said to be very feeding, though apt to prove laxative

to those unaccustomed to its use. It is drunk in a state of effervescence

or lively fermentation; the glass or cup containing it being kept in

constant motion, when removed from the mouth, until the whole is consumed,

in order that the thicker portion may not subside to the bottom.

=Ales, Med'icated.= _Syn._ BRYT'OLES; BRUTOLÉS, Fr.; CEREVIS'IÆ MEDICA'TÆ,

L. In _pharmacy_, ale prepared by macerating medicinal substances in it,

either at the ordinary temperature of the atmosphere, or when heated;

infusions and decoctions, in which ale or beer is employed as the

menstruum. The old dispensatories enumerate several medicated ales; such

as CEREVISIA OXYDOR'CICA, for the eyes; C. ANTI-ARTHRIT'ICA, for the gout;

C. CEPHAL'ICA, for the head; C. EPILEP'TICA, against epilepsy; &c.

Preparations of this kind are now seldom ordered by the faculty, and their

use is chiefly confined to the practice of empirics, and to domestic

medicine. Bark, rue, savine, antiscorbutic plants, aromatic bitters, and

stomachics, are the substances most commonly administered in this way. Ale

in which wormwood, gentian, orange-peel, and the like, have been steeped,

taken warm early in the morning, is much esteemed as a restorative tonic

by drunkards and dyspeptics. See BEER, PURL, &c.

=ALE'BERRY.= A beverage made by boiling ale with spice, sugar, and

bread-sops; the last commonly toasted. A domestic remedy for a cold.

=ALE'GILL= (_g_ hard). Ale or beer flavoured or medicated by infusing the

leaves of ground ivy in it; pectoral, stomachic, and nervine.

=ALE'WIFE.= The _clupea serrata_, an American species of herring. Its

proper name is a'loof, although the established pronunciation and common

orthography is ale-wife.

[Illustration]

=ALEM'BIC.= _Syn._ MOORS'HEAD[dagger]; ALEM'BICUS, L.; ALAMBIC, Fr.;

DESTILLIRKOLBEN, Ger. An old form of distillatory vessel usually made of

glass or earthenware, but sometimes of metal. The body (_a_) which holds

the liquid for distillation is called the CU'CURBIT; the upper part (_b_)

the HEAD or CAP'ITOL; (_c_) is the RECEIVER. It is still employed in the

laboratory, in the distillation of articles that are apt to spurt over

into the neck of the common retort, and thus vitiate the product.

=ALEUROM'ETER.= _Syn._ ALEUROMÈTRE, Fr. An instrument for determining the

quantity and quality of gluten in wheat-flour, invented by M. Boland. It

essentially consists of a hollow copper cylinder, about 6 inches long, and

3/4 of an inch internal diameter. This tube has two principal parts; the

one, about 2 inches long, is closed at the lower end, forming a kind of

cup, into which the gluten is placed; it screws into the remainder of the

cylinder. The cup being charged with a sample of gluten, and the upper

part of the cylinder being screwed on, it is exposed in an oven, or

(preferably) in an oil bath, to a temperature of 350 to 380° Fahr.[17]

From the length of the tube the gluten occupies in swelling, as measured

by a graduated scale, its quality is determined. The 'crude gluten' of

good wheat-flour augments to four or five times its original volume, when

thus treated; but that from bad flour does not swell, becomes viscid and

semi-fluid, and generally gives off a disagreeable odour; whilst that of

good flour merely suggests the smell of hot and highly baked bread.

[Footnote 17: Mr Mitchell recommends the heat to be 420°; whilst Dr

Masprett gives 284° Fahr. as the proper temperature; but of these the

first is too high, and the other too low. About 210 gr. are also ordered

to be taken for examination; but the exact quantity is immaterial. (See

Mitchell's 'Falsification of Food.')]

=AL'GA.= (-g[)a]). [L.] Sea-weed. A common name of grass-wrack ('zostera

marina'--Linn.), though not one of the algæ.

=AL'GÆ.= ([)a]l'-j[=e]). [L. pl.] _Syn._ AL'GALS; ALGÆ (DC.), AL'GALES

(Lindl.), L.; ALGUES, VARECH, Fr.; ALGE, MEERGRASS, SEEGRASS, Ger.

Sea-weeds. In _botany_, an order of Thallogens living in water or very

moist places, nourished throughout their whole surface by the medium in

which they live, having no distinct axis of vegetation, and propagated by

zoöspores, coloured spores, or tetraspores. Linnæus defines them--"plants,

the roots, leaves, and stems of which are all in one." The algæ consist

either of simple vesicles lying in mucus, or of articulated filaments, or

of lobed fronds formed of uniform cellular tissue. Those that vegetate in

salt water are popularly called SEA-WEEDS (fu'ci, L.) and LA'VER (ulvæ,

L.); those found in fresh water CONFER'VÆ. One of their divisions (the

_Zoöspermeæ_) comprehends the lowest known forms of vegetable life, being

merely adhering cells, emitting, at maturity, seeds or sporules having a

distinct animal motion. In _Oscillatorias_, the whole plant twists and

writhes spontaneously; and _Zymenas_ actually copulate like animals. Some

of the Algæ possess great beauty. In the lower grades the colour is green;

in the higher, red or purple.

_Prop., Uses, &c._ None of the Algæ are poisonous. Several are nutritious,

emollient, and demulcent, from containing mucilage (carrageenin), starch,

sugar (mannite), and a little albumen; and are hence used as esculents.

The ash from the dried weed varies in different varieties from 9% to fully

25%; and contains variable quantities of potassa, soda, lime, magnesia,

iron, manganese, and silica, with sulphuric acid, phosphoric acid,

chlorine, and a little iodine and bromine. (Schweitzer; Forchhammer;

Gödechens.) Sea-weeds, their charcoal, and their ashes, have been long

regarded as alterative and resolvent; and anti-phthisic virtues have been

attributed to them by Laennec and others. They were formerly much given in

scrofulous affections and glandular enlargements; but their use is now

almost superseded by that of iodine and its preparations. Dr Stenhouse has

proposed some of the algæ as furnishing an economical source of mannite.

The sea algæ are used for manure; their ashes form KELP.

The following table, showing the results of several analyses of different

kinds of algæ, and illustrating the very large amount of nitrogen

contained in them, is from Mr Walter Blyth's excellent dictionary of

'Hygiene and Public Health.'

From the above, we learn the important fact that the sea-weeds found on

our coasts are amongst the most nutritious of vegetable substances, and

that they, when dry, are even richer in nitrogenous matter than either

oatmeal or Indian corn in the same state. The following are the chief

varieties of algæ which are used as food by the dwellers on our coasts as

well as on the continent:--PORPHYRA LACINIATA and VULGARIS, called _laver_

in England, _stoke_ in Ireland, and _slouk_ in Scotland. CHONDRUS CRISPUS,

called _carrageen_ or _Irish moss_, and also _pearl-moss_, and _sea-moss._

LAMINARIA DIGITATA, known as the _sea-girdle_ in England, _tangle_ in

Scotland, and _red-ware_ in the Orkneys; and LAMINARIA SACCHARINA, ALARIA

ESCULENTA, or _bladder-lock_, called also _henware_, and _honey-ware_ by

the Scotch. ULVA LATISSIMA or GREEN LAVER--RHODOMENIA PALMATA or _dulse_

of Scotland. Under the name of "marine sauce" the LAVER was esteemed a

luxury in London, where it may now occasionally be met with in the shops

of provision merchants. The employment of the CHONDRUS CRISPUS or

_Carrageen_ in the form of an aliment for consumptive and weakly persons,

would seem from the analysis of it given above to be fully justified. In

preparing the algæ for food, they must be soaked in water to remove the

saline matter, and where they are possessed of a bitter flavour this may

be removed by adding a little carbonate of soda to the water. They should

then be stewed in water or milk till they are tender. The best flavourings

are pepper and vinegar. See JELLY.

=ALGARO'BA.= _Syn._ CA''ROB-TREE, ST. JOHN'S BREAD; CERATO'NIA SIL'IQUA,

Linn. A leguminous tree of southern Europe, Palestine, and part of Africa.

Pods (ALGAROBA BEANS), used for food, and to improve the voice; they

contain a sweetish, nutritious powder, and are supposed to have been the

'locusts' on which St. John fed in the wilderness; their decoction has

been used as a pectoral in asthma and coughs.

=Algaroba or Algarovil'la.= The astringent pods of prosopis pallida, p.

siliquastrum, and Inga Marthæ (South American trees), bruised and more or

less agglutinated by the extractive exudation of the seed and husks. They

are used in tanning, for which purpose they have been strongly

recommended; indeed that of Chili, and of Santa Martha (New Carthagena),

is said to possess "four times the power of good oak bark" (Ure); and in

dyeing are only inferior to oak-galls.

=ALGONTINE.= A mouth and tooth wash. An aqueous solution of nitrate of

potassium, aromatised with oil of peppermint, tincture of myrrh, and

tincture of cinnamon.

=ALGOPHON= (Bernhard, Salzburg). For pains in decayed teeth. A solution of

ethereal oil of mustard (2 grms.) in spirit of cochlearia (30 grms.),

coloured green by saffron and litmus. (Wittstein.)

=AL'IMENT.= [Eng., Fr.] _Syn._ ALIMEN'TUM, L.; NAHRUNG, SPEISE, Ger. Food;

nutriment; anything which nourishes or supports life.

=ALIMENT'ARY= _Syn._ ALIMENTA''RIUS, L.; ALIMENTAIRE, Fr.; ZUR NAHRUNG

GEHÖRIG, Ger. Pertaining to food or aliment; nutrimental; nourishing.

=Alimentary Canal'.= _Syn._ ALIMENTARY DUCT; CANA'LIS ALIMENTA''RIUS, L.

In _anatomy_, the cavity in the bodies of animals into which the food is

taken for the purpose of being digested; the whole passage or conduit

extending from the mouth to the anus. In some of the lower animals this is

a simple cavity, with only one opening; when the same aperture which

admits the food also gives egress to the excrementitious matter. In others

it is a true canal, with both a mouth and an outlet. Another step, and we

find this canal is divided into a stomach and intestines. In the higher

grades, a mouth, pharynx, and [oe]sophagus precede the stomach. Birds have

one or two sacculi or crops added to the [oe]sophagus. The stomach of the

ruminants consists of four sacs or parts, each of which may be regarded as

a separate stomach; that of the bottle-nose whale contains no less than

seven of such sacs. The part below the stomach, forming the intestines, is

also variously subdivided, complicated, and connected. In man, these

subdivisions are termed--DUODENUM, JEJU'NUM, IL'EUM, CÆ'CUM, CO'LON, and

REC'TUM; the lower end or orifice of the last being called the A'NUS. The

existence of an alimentary canal is said to be the only true

characteristic of an animal. Plants have no common receptacle for their

food, nor canal for carrying away effete matter; but every animal, however

low in the scale of being, possesses an internal cavity which serves it as

a stomach.

=Alimentary Sub'stances.= _Syn._ ALIMENTS; MATE''RIA ALIMENTA''RIA, L.

Substances employed as food.

=ALIMENTA'TION.= [Eng., Fr.] _Syn._ ALIMENTA'TIO, L.; NAHRHAFTIGKEIT, Ger.

The act, process, power, or state of nourishing, or being nourished.

=AL'IZARI.= [Tur., ali-zari.] The commercial name of madder in the Levant.

=ALIZARIN.= C_{10}H_{6}O_{3} . 2H_{2}O. _Syn._ LAZARIC ACID. A red

colouring matter obtained from madder.

_Prep._ 1. Exhaust madder with boiling water, and precipitate the

decoction by sulphuric acid. Wash the precipitate, and, while yet moist,

boil it with a concentrated solution of hydrate of aluminum in

hydrochloric acid, and mix the solution with hydrochloric acid; red flakes

of impure alizarin deposit. Dissolve this precipitate in alcohol or in

dilute ammonia, and treat the solution with hydrate of aluminum. Boil the

aluminum compound thus formed with carbonate of sodium, and, after freeing

it from resinous impurities by digestion with ether, decompose it with hot

hydrochloric acid. Wash the alizarin thus separated, dry it by simple

exposure to air, and purify it by repeated crystallisation out of alcohol.

2. Sublime on a paper an alcoholic extract of madder. This method yields

the purest alizarin.

_Props._ Red prisms; sublimes at 419° F.; odourless, tasteless, and

neutral to test-paper; sparingly soluble in water, even at the boiling

temperature; soluble in alcohol and ether; not decomposed by hydrochloric

acid; dissolved, without decomposition, by strong sulphuric acid; soluble

in solutions of the alkalies and their carbonates; acids precipitate

alizarin from its alkaline solutions in orange-coloured flakes; alumina

decolorises an alcoholic solution of alizarin, forming a red lake.

=ALIZARIN, ARTIFICIAL.= C_{14}H_{8}O_{4}. This colour was first obtained

by Graebe and Liebermann in 1869 from anthrachinon, an oxidation product

of anthracen, this latter being a substance which is formed during the

destructive distillation of coal-tar. These chemists converted anthracen

into antichinon by means of nitric acid.

The crude anthracen is previously purified by treatment with benzoline

(petroleum spirit), aided by heat, and by being subjected to the action of

the centrifugal machine to fusion, and to sublimation.

According to the original method of preparing alizarin, the anthrachinon

was first converted into a dibromide of anthrachinon by treatment with

bromine, and this bromated compound, by further treatment either with

caustic potash or soda at a temperature of 180° to 200° C., converted into

alizarin-potassium (or alizarin-sodium if caustic soda has been used),

from which the alizarin is set free by means of hydrochloric acid.

Alizarin is now procured from anthrachinon by treatment at a temperature

of 260° C., with concentrated sulphuric acid of 1·84 sp. gr., the

anthrachinon being converted into a sulpho-acid; this acid is next

neutralised with carbonate of lime, the fluid decanted from the deposited

sulphate of lime, and carbonate of potash added to it, with the object of

throwing down all the lime. The clear liquid is then evaporated to

dryness, the resulting saline mass is converted into alizarin-potassium by

heating it with caustic potash. From the alizarin-potassium thus obtained

the alizarin is set free by the aid of hydrochloric acid.

In another method the preparation of anthrachinon is avoided, and

anthracen employed directly, by first converting it, by means of sulphuric

acid and heat, into anthracen sulphonic-acid. After having been diluted

with water, the solution of this acid is treated with oxidising agents

(peroxides of manganese, lead, chromic acid, nitric acid), and the acid

fluid is afterwards neutralised with carbonate of lime. When peroxide of

manganese has been used, the manganese is also precipitated as oxide. The

oxidised sulpho-acid having been previously converted into a potassium

salt, the latter being heated with caustic potash, alizarin is obtained.

The details of these two processes will be found set forth in the terms of

the patent taken out by Messrs Caro, Graebe and Liebermann, further on.

The following method of preparing alizarin from anthracene paranaphthalene

and their homologues is by Girard. The material used is that which distils

between 290° and 360°; it is purified by distillation and pressure, the

portion which passes over, between 300° and 305°, being collected

separately. This mixture is treated with potassium chlorate and

hydrochloric acid, whereby it is converted into tetra-chlorinated

products. These are oxidised either by nitric acid in the water bath, or

by a metallic oxide (red or brown oxide of lead), and sulphuric or acetic

acid. In the first place a mixture of dichloranthraquinine and chloride of

chloroxyanthranyl are obtained. These substances are treated in presence

of a metallic oxide (oxide of zinc, oxide of copper, or litharge), with an

alcoholic solution of sodium acetate. The metallic oxide removes the last

atom of chlorine from the sodium chloroxyanthranilate, and converts it,

like the dichloranthraquinine, into alizarin. The purification is effected

by means of benzine, petroleum, &c., which dissolve out the foreign

matters, and by successive precipitation from the alkaline solutions by

mineral acids. The foreign matters may also be separated by means of a

little alum, when it is necessary to work with neutral potash or soda

salts.

Another method for the preparation of alizarin has been patented by Dale

and Schorlemmer. It is as follows: 1 part of anthracen is boiled with 4 to

10 parts of strong sulphuric acid, then diluted with water, and the

solution neutralised with carbonate of calcium, barium, potassium, or

sodium. The resulting sulphates having been removed by nitration or

crystallisation, the solution is heated to between 180° and 260° with

caustic potash or soda, to which a quantity of potassium nitrate or

chlorate has been added, about equal in weight to the anthracen, as long

as a blue-violet colour is thereby produced. From this product the

alizarin is separated in the usual way by precipitation with an acid.

Several other patents have been taken out for the preparation of

artificial alizarin.

The specification of Messrs Caro, Graebe, and Liebermann, and dated June

25th, 1869, was the first which was taken out in England. We quote it here

because it enters more fully into detail than any of the others.

"Our invention is carried into effect by means of either of the two

processes which we will proceed to describe.

"In the one process we proceed as follows--We take about one part by

weight of anthraquinone and about three parts by weight of sulphuric acid

of about specific gravity of 1·488, and introduce the same into a retort,

which may be made of glass, or porcelain, or of any other material not

easily acted upon by sulphuric acid, and the contents are then to be

heated up to about 260° Centigrade, and the temperature is maintained

until the mixture is found no longer to contain any appreciable quantity

of unaltered anthraquinone. The completion of this operation may be

ascertained or tested by withdrawing a small portion of the product from

time to time, and continuing the operation at the high temperature until

such product upon being diluted with water is found to form a

substantially perfect solution, thereby indicating that the anthraquinone

has become either entirely or in greater part converted into the desired

product. The products thus obtained are then allowed to cool, and are

diluted with water; carbonate of lime is then added in order to neutralise

and remove the excess of sulphuric acid contained in the solution; the

mixture is then filtered, and to the filtrate carbonate of potash, or

carbonate of soda, by preference in solution, is to be added until

carbonate of lime is no longer precipitated; the mixture is then filtered,

and the clear solution is evaporated to dryness, by which means the potash

or soda salts of the sulpho-acids of anthraquinone are obtained, and which

are to be treated in the following manner:--We take about one part by

weight of this product, and from two to three parts by weight of solid

caustic, soda, or potash; water may be added or not, but by preference we

add as much water as is necessary to dissolve the alkali after admixture;

we heat the whole in a suitable vessel, and the heating operation is

continued at a temperature of from about 180° to 260° Centigrade, for

about one hour, or until a portion of the mixture is found upon

withdrawing and testing it to give a solution in water, which being

acidulated with an acid, for example, sulphuric acid, will give a copious

precipitate of the colouring matters. The heating operation having been

found to have been continued for a sufficient time, the resulting products

are then dissolved in water, and we either filter or decant the solution

of the same, from which we precipitate the colouring matters or artificial

alizarin, by means of a mineral or organic acid, such, for example, as

sulphuric or acetic acid. The precipitated colouring matters thus obtained

are collected in a filter or otherwise, and after having been washed may

be employed for the purpose of dyeing and printing, either in the same way

as preparations of madder are now used or otherwise.

"In carrying out our other process we proceed as follows:--We take about

one part by weight of anthracene and about four parts by weight of

sulphuric acid of specific gravity of about 1·848, and the mixture being

contained in a suitable vessel, is heated to a temperature of about 100°

Centigrade, and which temperature is to be maintained for the space of

about three hours; the temperature is then to be raised to about 150°

Centigrade, which temperature is to be maintained for about one hour, or

until a small portion of the product when submitted to the two subsequent

processes hereinafter described is found to produce the desired colouring

matters; we then allow the result obtained by this operation to cool, and

dilute it with water, by preference in the proportion of about three times

its weight. To the solution thus obtained we add for every part of

anthracene by weight which had been employed in the previous operations,

from about two to three parts by weight of peroxide of manganese,

preferring to employ an excess, and we boil the whole strongly for some

time, and in order fully to ensure the desired degree of oxidation the

mixture may be subsequently concentrated, and by preference be evaporated

to dryness, and the heat be continued until a small portion of the

oxidised product, when submitted to the subsequent processes hereinafter

described will produce the desired colouring matters. We then neutralise

and remove the sulphuric acid contained in this mixture, and at the same

time precipitate any oxides of manganese that may be held in solution, by

adding an excess of caustic lime, which we use by preference in the form

of milk of lime, and we add the same until the mixture has an alkaline

reaction. We then filter, and add to the filtrate carbonate of potash or

soda, until there is no further precipitation of carbonate of lime. The

solution is then filtered and evaporated to dryness, and we thus obtain

the potash or soda salts of what we call the sulpho-acids of

anthraquinone.

"In effecting the conversion of the oxidised products thus obtained into

colouring matters, or into what we call artificial alizarin, we proceed as

follows:--We take one part by weight of this product, and from two to

three parts by weight of solid caustic soda or potash, and water may be

added or not, but by preference we add as much water as may be necessary

to dissolve the alkali. After admixture we heat the whole in a suitable

vessel, and continue the heating operation at a temperature of about 180°

to about 260° Centigrade for about one hour, or until a portion of the

mixture is found to give a solution in water, which upon acidulation with

an acid, for example, sulphuric acid, is found to give a copious

precipitate of the colouring matters. The heating operation having been

found to have been continued for a sufficient time, we then dissolve the

product in water, and either filter or decant the solution of the same,

from which we precipitate the colouring matters or artificial alizarin by

means of a mineral or organic acid, such, for example, as sulphuric or

acetic acid. The precipitated colouring matters thus obtained are

collected on a filter or otherwise, and after having been washed may be

employed for the purpose of dyeing and printing, either in the same way as

preparations of madder are now used or otherwise.

"Instead of acting upon anthracen by means of sulphuric acid of the

density before mentioned, fuming sulphuric acid may be employed, but we

prefer to use the ordinary kind before described.

"In order to effect the process of oxidation, before referred to, other

oxidising agents may be used in the place of the oxide of manganese,

before mentioned, such, for example, as perioxide of lead, or chromic,

nitric, or other acids capable of effecting the desired oxidation may be

employed."

Mr W. H. Perkin's patent is similar in principle to that of Messrs Caro,

Graebe, and Liebermann, and is dated only one day later.

The following is an outline of a patent taken out in France in May, 1869,

by MM. Br[oe]nner and Gutzkon, for the manufacture of artificial alizarin.

One part of anthracen is heated with two parts of nitric acid, sp. gr. 1·3

to 1·5. The anthraquinone thus produced is washed and dissolved at a

moderate heat in sulphuric acid. Mercuric nitrate is now added, which

converts the anthraquinone into alizarin, The mass thus formed is

dissolved in an excess of alkali, which precipitates the oxide of mercury,

and retains the colouring matters in solution. The alkaline liquor is

decanted and neutralised with sulphuric acid, and the precipitate thus

formed is washed and collected. If not quite pure the treatment with

alkali must be repeated. (The complete specification of this patent is

published in the 'Moniteur Scientifique,' vol. xi, p. 865.)

In England a large quantity of artificial alizarin is manufactured by the

process of Mr Perkin, and is used as a substitute for madder and madder

extract, in Turkey red dyeing and topical styles. The largest makers of

artificial alizarin on the continent are Messrs Gessert Frères, of

Ebelfort, Messrs Maister, Lucius and Co., of Hæchst, near Frankfort, and

the Badische Anilin und Soda Fabric, Mannheim.

The following recipes for printing with artificial alizarin are extracted
