"About the year 1650 an unknown Italian came to Geneva and took

lodgings at the sign of the Green Cross. After remaining there a day

or two, he requested De Luc, the landlord, to procure him a man

acquainted with Italian, to accompany him through the town and point

out those things which deserved to be examined. De Luc was

acquainted with M. Gros, at that time about twenty years of age, and

a student in Geneva, and knowing his proficiency in the Italian

language, requested him to accompany the stranger. To this

proposition he willingly acceded, and attended the Italian

everywhere for the space of a fortnight. The stranger now began to

complain of want of money, which alarmed M. Gros not a little, for

at that time he was very poor, and he became apprehensive, from the

tenor of the stranger's conversation, that he intended to ask the

loan of money from him. But instead of this, the Italian asked him

if he was acquainted with any goldsmith, whose bellows and other

utensils they might be permitted to use, and who would not refuse to

supply them with the different articles requisite for a particular

process which he wanted to perform. M. Gros named a M. Bureau, to

whom the Italian immediately repaired. He readily furnished

crucibles, pure tin, quicksilver, and the other things required by

the Italian. The goldsmith left his workshop, that the Italian might

be under the less restraint, leaving M. Gros, with one of his own

workmen as an attendant. The Italian put a quantity of tin into one

crucible, and a quantity of quicksilver into another. The tin was

melted in the fire and the mercury heated. It was then poured into

the melted tin, and at the same time a red powder enclosed in wax

was projected into the amalgam. An agitation took place and a great

deal of smoke was exhaled from the crucible; but this speedily

subsided, and the whole being poured out, formed six heavy ingots,

having the color of gold. The goldsmith was called in by the Italian

and requested to make a rigid examination of the smallest of these

ingots. The goldsmith not content with the touch-stone and the

application of aquafortis, exposed the metal on the cupel with lead

and fused it with antimony, but it sustained no loss. He found it

possessed of the ductility and specific gravity of gold; and full of

admiration, he exclaimed that he had never worked before upon gold

so perfectly pure. The Italian made him a present of the smallest

ingot as a recompense and then, accompanied by M. Gros, he repaired

to the mint, where he received from M. Bacuet, the mint-master, a

quantity of Spanish gold coin, equal in weight to the ingots which

he had brought. To M. Gros he made a present of twenty pieces on

account of the attention that he had paid to him and after paying

his bill at the inn, he added fifteen pieces more, to serve to

entertain M. Gros and M. Bureau for some days, and in the meantime

he ordered a supper, that he might, on his return, have the pleasure

of supping with these two gentlemen. He went out, but never

returned, leaving behind him the greatest regret and admiration. It

is needless to add that M. Gros and M. Bureau continued to enjoy

themselves at the inn till the fifteen pieces which the stranger had

left, were exhausted."

Narratives such as these led even Bergman, a very able chemist of the

period, to take the ground that "although most of these relations are

deceptive and many uncertain, some bear such character and testimony

that, unless we reject all historical evidence, we must allow them

entitled to confidence."

A much more probable explanation is that the relators were either

dreaming or deceived by clever legerdemain.

Of the possibility or impossibility of converting the more common metals

into gold or silver, it would be rash to give a positive opinion. To say

that gold, silver, lead, copper, etc., are elements and cannot be

changed, is merely to say that we have not been able to decompose them.

Water, potash, soda, and other substances, were at one time considered

elements, and resisted all the efforts of the older chemists to resolve

them into their components, but with the advent of more powerful means

of analysis they were shown to be compounds, and it is not impossible

that the so-called elements into which they were resolved may themselves

be found to be compounds. This has happened in regard to some substances

which were at one time announced as elements, and it is not impossible

that it may happen in regard to others. The ablest chemists of the

present day recognize this fully and are prepared for radical changes in

our knowledge of the nature and constitution of matter. Amongst the new

views is the hypothesis of Rutherford and Soddy, which, as given by Sir

William Ramsay, in a recent article contributed by him to "Harper's

Magazine," is that,

"atoms of elements of high atomic weight, such as radium, uranium,

thorium, and the suspected elements polonium and actinium, are

unstable; that they undergo spontaneous change into other forms of

matter, themselves radioactive and themselves unstable; and that

finally elements are produced, which, on account of their

non-radioactivity, are as a rule, impossible to recognize, for their

minute amount precludes the application of any ordinary test with

success. The recognition of helium however, which is comparatively

easy of detection, lends great support to this hypothesis."

At the same time we must not lose sight of the fact that the substances

which we now recognize as elements have not only resisted the most

powerful analytical agencies and dissociating forces, but have

maintained their elemental character in spectrum analysis, and shown

their presence as distinct elements in the sun and other heavenly bodies

where they must have been subjected to the action of the most energetic

decomposing forces. So that in the present state of our knowledge the

near prospect of successful transmutation does not seem to be very

bright, although we cannot regard it as impossible. In the article from

which we have already quoted, Sir William Ramsay, after discussing the

bearing of certain experiments in regard to the parting with and

absorbing of energy by certain elements, says: "If these hypotheses are

just, then the transmutation of the elements no longer appears an idle

dream. The philosopher's stone will have been discovered, and it is not

beyond the bounds of possibility that it may lead to that other goal of

the philosophers of the dark ages--the _elixir vitae_. For the action of

living cells is also dependent on the nature and direction of the energy

which they contain; and who can say that it will be impossible to

control their action, when the means of imparting and controlling energy

shall have been investigated!"

In the event of the discovery of a cheap method of producing gold, the

change which would certainly occur in our financial or currency system

would be important, if not revolutionary. It has become the fashion at

present with certain writers to scout the so-called "quantitative

theory" of money as if it were an exposed fallacy. Now the quantitative

theory of money rests on one of the most well-grounded and firmly

established principles in political economy: the trouble is that the

writers in question do not understand it or even know what it is. At

present, the production of gold barely keeps pace with the increasing

demand for the metal as currency and in the arts, but if that

production were increased ten-fold, the value of gold would decline and

prices would go up astonishingly.

One of the objects which the better class of alchemists had in view was

the making of gold to such an extent that it might become quite common

and cease to be sought after by mankind. One alchemical writer says:

"Would to God that all men might become adepts in our art, for then

gold, the common idol of mankind, would lose its value and we should

prize it only for its scientific teaching."

THE FIXATION OF MERCURY

This is really one of the processes supposed to be involved in the

transmutation of the metals and might, therefore, perhaps, with

propriety, be included under that head. But as it has received special

attention in the apocryphal works of Hermes Trismegistus, who is

generally regarded as the Father of Alchemy, it is frequently mentioned

as one of the old scientific problems. Readers of Scott's novel,

"Kenilworth," may remember that Wayland Smith, in his account of his

former master, Demetrius Doboobius, describes him as a profound chemist

who had "made several efforts to fix mercury, and judged himself to have

made a fair hit at the philosopher's stone." Hermes, or, rather, those

who wrote over his name, speaks in the jargon of the adepts, about

"catching the flying bird," by which is meant mercury, and "drowning it

so that it may fly no more." The usual means for effecting this was

amalgamation with gold, or some other metal or solution in some acid.

To the ancient chemists mercury must have been one of the most

interesting of objects. Its great heaviness, its metallic brilliancy,

and its wonderful mobility, must all have combined to render it a

subject for deep thought and an attractive object for experiment and

investigation.

Living in a warm climate, as they did, there was no means at their

command by which its fluidity could be impaired. This subtle substance

seemed to defy the usual attempts to grasp it; it rolled about like a

solid sphere, but offered no resistance to the touch, and when pressed

it split up into innumerable smaller globules so that the problem of

"fixing" it must have had a strange fascination for the thoughtful

alchemist, especially when he found that, on subjection to a

comparatively moderate degree of heat, this heavy metal disappeared in

vapor and left not a trace behind.

I have often wondered what the old alchemists would have said if they

had seen fluid mercury immersed in a clear liquid and brought out in the

form of a lump of solid, bright metal. For, although this is not in any

sense a solution of the problem, yet it is a most curious sight and one

which was rarely seen before the discovery of the liquefaction of the

gases. To Geber, Basil Valentine, Van Helmont, Helvetius, and men of

their day, living in their climate, this startling phenomenon would have

seemed nothing short of a miracle.

In modern times the solidification of mercury had been frequently

witnessed by these who dwelt in northern climates and by the skilful use

of certain freezing mixtures made up of ordinary salts, it is not

difficult to exhibit this metal in the solid state at any time. But it

was not until the discovery of the liquefaction of carbonic acid,

nitrous oxide, and other gases by Faraday, about 1823, that the freezing

of mercury became a common lecture-room experiment.

In the year 1862 the writer delivered a course of lectures on chemistry,

in the city of Rochester, N. Y., and during the progress of these

lectures he reduced carbonic acid first to the liquid, and then to the

solid state, in the form of a white snow. The temperature of this snow

was about -80 deg. Cent. (-176 deg. Fahr.) and when it was mixed with ether and

laid on a quantity of mercury, the latter was quickly frozen. In this

way it was easy to make a hammer-head of frozen mercury and drive a nail

with it.

Another very interesting experiment was the freezing of a slender

triangular bar of mercury which might be twisted, bent, and tied in a

knot. This was done by folding a long strip of very stiff paper so as to

make an angular trough into which the mercury was poured. This trough

was then carefully leveled and a mixture of solid carbonic acid and

ether was placed over the metal in the usual way. In a few seconds the

mercury was frozen quite solid so that it could be lifted out by means

of two pairs of wooden forceps and bent and knotted at will. But the

most striking part of the experiment was the melting of this bar of

mercury by means of a piece of ice. The moment the ice touched the

mercury, the latter melted and fell down in drops in the same way that a

bar of lead or solder melts when it is touched with a red-hot iron.

The melted mercury was allowed to fall into a tall ale-glass of water,

the temperature of which had been reduced as nearly as possible to the

freezing point. When the mercury came in contact with the cold water,

the latter began to freeze and by careful manipulation it was possible

to freeze a tube of ice through the center of the column of water. The

effect of this under proper illumination was very striking.

Owing to the fact that the specific heat or thermal capacity of mercury

is only about one-thirtieth of that of water, it requires a considerable

amount of melted mercury to produce the desired result.

But these processes do not enable us to fix mercury in the alchemical

sense; the accomplishment of that still remains an unsolved problem, and

it is more than likely that it will remain so.

THE UNIVERSAL MEDICINE AND THE ELIXIR OF LIFE

Love of life is a characteristic of all animals, man included, and

notwithstanding the fact that an occasional individual becomes so

dissatisfied with his environment that he commits suicide, and also in

the face of the poet's assertion that

"protracted life is but protracted woe"

most men and women are of the same way of thinking as Charmian, the

attendant on Cleopatra, and "love long life better than figs." And the

force of this general feeling is appealed to in the only one of the

Mosaic commandments to which a promise is attached, the inducement for

honoring father and mother being "that thy days may be long in the land

that the Lord thy God giveth thee."

No wonder then that the old alchemists dreamed of a universal medicine

that would not only prevent or cure sickness but that would renew the

youth of the aged and the feeble, for in this, as in most other attempts

at discovery, the wish was father to the thought. That the renewal of

youth in the aged was supposed to be within the ability of the magicians

and gods of old, we gather from the stories of Medea and Aeson and the

ivory shoulder of Pelops, as referred to in Shakespeare, and explained

in the "Shakespeare Cyclopedia."

Of the form of this supposed elixir we know very little for the

language of the alchemists was so vague and mystical that it is often

very difficult to ascertain their meaning with any approach to

certainty. The following, which is a fair sample of their metaphorical

modes of expressing themselves, is found in the works of Geber. In one

of his writings, he exclaims: "Bring me the six lepers that I may

cleanse them." Modern commentators explain this as being his mode of

telling his readers that he would convert into gold the six inferior or,

as they were called by the alchemists, the six imperfect metals. No

wonder that Dr. Johnson adopted the idea that the word _gibberish_

(anciently written _geberish_) owed its origin to an epithet applied to

the language of Geber and his tribe.

Some have claimed that the elixir and the philosopher's stone were one

and the same thing, and some of the writings of the old alchemists would

seem to confirm this view. Thus, at the close of a formula for preparing

the philosopher's stone, Carolus Musitanus gives the following

admonition:

"Thus friend, you have a description of the universal medicine, not

only for curing diseases and prolonging life, but also for

transmuting all metals into gold. Give therefore thanks to Almighty

God, who, taking pity on human calamities, has at last revealed this

inestimable treasure, and made it known for the benefit of all."

And Brande tells us that "nearly all the alchemists attributed the power

of prolonging life either to the philosopher's stone or to certain

preparations of gold, imagining possibly that the permanence of that

metal might be transferred to the human system. The celebrated Descartes

is said to have supported such opinions; he told Sir Kenelm Digby that

although he would not venture to promise immortality, he was certain

that life might be lengthened to the period of that of the Patriarchs.

His plan, however, seems to have been the very rational one of limiting

all excess of diet and enjoining punctual and frugal meals."

It is an old saying that history repeats itself. About forty years ago

certain medical practitioners strongly urged the use of salts of gold in

the treatment of disease, and great hopes were entertained in regard to

their efficacy. And the Keeley gold cure for drunkards is strongly in

evidence, even at the present day.

On the other hand, some have held that the elixir was quite distinct

from the stone by which metals might be transmuted into gold. In the

second part of "King Henry IV," Falstaff (Act III, Scene 2, line 355),

says of Shallow: "it shall go hard but I will make him a philosopher's

two stones to me," and this saying of his has given considerable trouble

to the commentators.

Warburton's explanation of this expression is, that "there was two

stones, one of which was a universal medicine and the other a transmuter

of base metals into gold." And in Churchyard's "Discourse and

Commendation of those that can make Gold," we read of Remundus, who

Wrate sundry workes, as well doth yet appeare

Of stone for gold, and shewed plaine and cleare

A stone for health.

Johnson and some others have objected to this explanation, but it seems

to be evident that Falstaff meant that he would get health and wealth

from Shallow. He got the wealth to the extent of a thousand pounds.

The intense desire which exists in the human bosom for an elixir that

will cure all diseases, and prolong life has made itself evident, even

in recent times, and has called forth serious efforts on the part of

men occupying prominent positions in the scientific world. Both in

Europe and in this country suggestions have been made of fluids which,

when injected into the veins of the old and the feeble, would renew

youth and impart fresh strength. But alas! the results thus far attained

have been anything but gratifying, and the probabilities against success

in this direction are very strong.

The latest gleam of light comes from discoveries in connection with the

radioactive elements, as the reader will find, on referring to Sir

William Ramsay's utterance, which is given at the close of the article

on the "Transmutation of the Metals," on a preceding page.

ADDITIONAL "FOLLIES"

In addition to the seven "Follies," of which an account has been given

in the preceding pages, there are a few which deserve to be classed with

them, although they do not find a place in the usual lists. These are

known as

PERPETUAL LAMPS.

THE ALKAHEST OR UNIVERSAL SOLVENT.

PALINGENESY.

THE POWDER OF SYMPATHY.

PERPETUAL OR EVER-BURNING LAMPS

Part of the sepulchral rites of the ancients consisted in placing

lighted lamps in the tombs or vaults in which the dead were laid, and,

in many cases, these lamps were carefully tended and kept continually

burning. Some authors have claimed, however, that these men of old were

able to construct lamps which burned perpetually and required no

attention. In number 379 of the "Spectator" there is an anecdote of some

one having opened the sepulcher of the famous Rosicrucius. There he

discovered a lamp burning which a statue of clock-work struck into

pieces. Hence, says the writer, the disciples of this visionary claimed

that he had made use of this method to show that he had re-invented the

ever-burning lamps of the ancients. And Fortunio Liceti wrote a book in

which he collected a large number of stories about lamps, said to have

been found burning in tombs or vaults. Ozanam fills eight closely

printed pages with a discussion of the subject.

Attempts have been made to explain many of the facts upon which is based

the claim that the ancients were able to construct perpetual lamps by

the suggestion that the light sometimes seen on the opening of ancient

tombs may have been due to the phosphorescence which is well known to

arise during the decomposition of animal and vegetable matter. Decaying

wood and dead fish are familiar objects which give out a light that is

sufficient to render dimly visible the outlines of surrounding objects,

and such a light, seen in the vicinity of an old lamp, might give rise

to the impression that the lamp had been actually burning and that it

had been blown out by sudden exposure to a draft of air.

Another supposition was that the flame, which was supposed to have been

seen, may have been caused by the ignition of gases arising from the

decomposition of dead bodies, and set on fire by the flambeaux or

candles of the investigators, and it is quite possible that the

occurrence of each of these phenomena may have given a certain degree of

confirmation to preconceived ideas.

After the discovery of phosphorus in 1669, by Brandt and Kunckel, it was

employed in the construction of luminous phials which could be carried

in the pocket, and which gave out sufficient light to enable the user to

see the hands of a watch on a dark night. Directions for making these

luminous phials are very simple, and may be found in most of the books

of experiments published prior to the introduction of the modern lucifer

match. They were also used for obtaining a light by means of the old

matches, which were tipped merely with a little sulphur, and which could

not be ignited by friction. Such a match, after being dipped into one of

these phosphorus bottles, would readily take fire by slight friction,

and some persons preferred this contrivance to the old flint and steel,

partly, no doubt, because it was a novelty. But these bottles were not

in any sense perpetual, the light being due to the slow oxidation of the

phosphorus so that, in a comparatively short time, the luminosity of the

materials ceased. Nevertheless, it has been suggested that some form of

these old luminous phials may have been the original perpetual lamp.

After the discovery of the phosphorescent qualities of barium sulphate

or Bolognian phosphorus, as it was called, it was thought that this

might be a re-discovery of the long-lost art of making perpetual lamps.

But it is well known that this substance loses its phosphorescent power

after being kept in the dark for some time, and that occasional exposure

to bright sun-light is one of the conditions absolutely essential to its

giving out any light at all. This condition does not exist in a dark

tomb.

A few years ago phosphorescent salts of barium and calcium were employed

in the manufacture of what was known as luminous paint. These materials

shine in the dark with brilliancy sufficient to enable the observer to

read words and numbers traced with them, but regular exposure to the

rays of the sun or some other bright light is absolutely necessary to

enable them to maintain their efficiency.

More recently it has been suggested that the ancients may have been

acquainted with some form of radioactive matter like radium, and that

this was the secret of the lamps in question. It is far more likely,

however, that the reports of their perpetual lamps were based upon mere

errors of observation.

The perpetual lamp is, in chemistry, the counterpart of perpetual motion

in mechanics--both violate the fundamental principle of the conservation

of energy. And just as suggestions of impossible movements have been

numerous in the case of perpetual motion, so impossible devices and

constructions have been suggested in regard to perpetual lamps. Prior to

the development, or even the suggestion of the law of the conservation

of energy, it was believed that it might be possible to find a liquid

which would burn without being consumed, and a wick which would feed

the liquid to the flame without being itself destroyed. Dr. Plott

suggested naphtha for the fluid and asbestos for the wick, but since

kerosene oil, naphtha, gasolene, and other liquids of the kind have

become common, every housewife knows that as her lamp burns, the oil, of

whatever kind it may be, disappears.

Under present conditions the construction of a perpetual lamp is not a

severely felt want; for constancy and brilliancy our present means of

illumination are sufficient for almost all our requirements. Whether or

not it would be possible to gather up those natural currents of

electricity, which are suspected to flow through and over the earth, and

utilize them for purposes of illumination, however feeble, it might be

difficult to decide. But such means of perpetual electric lighting would

be similar to a perpetual motion derived from a mountain stream. Such

natural means of illumination already exist, and have existed for ages

in the fire-giving wells of naphtha which are found on the shores of the

Caspian sea, and in other parts of the east, and which have long been

objects of adoration to the fire-worshippers.

As for the outcome of present researches into the properties of radium,

polonium, and similar substances, and their possible applications, it is

too early to form even a surmise.

THE ALKAHEST OR UNIVERSAL SOLVENT

The production of a universal solvent or alkahest was one of the special

problems of the alchemists in their general search for the philosopher's

stone and the means of transmuting the so-called inferior metals into

gold and silver. Their idea of the way in which it would aid them to

attain these ends does not seem to be very clearly stated in any work

that I have consulted; probably they thought that a universal solvent

would wash away all impurities from common materials and leave in

absolute purity the higher substance, which constituted the gold of the

adepts. But whatever their particular object may have been, it is well

known that much time and labor were expended in the fruitless search.

The futility of such attempts was very well exposed by the cynical

sceptic, who asked them what kind of vessel could they provide for

holding such a liquid? If its solvent powers are such that it dissolves

everything, it is very evident that it would dissolve the very material

of the vessel in which it must be placed.

When hydrofluoric acid became a subject of investigation it was thought

that its characteristics approached, more nearly than those of any other

substance known, to those of the universal solvent, and the very

difficulty above suggested, presented itself strongly to the chemists

who experimented with it. Not only common metals but glass and porcelain

were acted upon by this wonderfully energetic liquid and when attempts

were made to isolate the fluorine, even the platinum electrodes were

corroded and destroyed. Vessels of pure silver and of lead served

tolerably well, but Davy suggested that the most scientific method of

constructing a containing vessel would be to use a compound in which

fluorine was already present to the point of saturation. As there is a

limit to the amount of fluorine with which any base can combine, such a

vessel would be proof against its solvent action. I am not aware,

however, that the suggestion was ever carried into actual practice with

success.
