The diseases in which the Ballston and Saratoga waters have been

recommended are dyspepsia, hypochondriasis, hysteria, dropsy,

paralysis, chronic gout, rheumatism, chlorosis, suppression of the

menses, and diseases of the bladder and kidneys. The waters of

Schooley’s Mountain, besides their general utility in diseases of the

digestive organs, have proved eminently successful in calculous

affections. _Ed._

Footnote 394:

For the same purpose the French employ a pomatum prepared with the

oxide of bismuth, and it is said to answer the intention.

Footnote 395:

PERMANENT INK FOR MARKING LINEN. This preparation is a solution of

nitrate of silver, thickened with sap green, or cochineal. The

preparing liquid, or Pounce liquid, as it is technically called, with

which the linen to be marked is previously wetted, is a solution of

soda, boiled with gum, or some animal mucilage. It is a curious

circumstance, that if potass be used for this purpose, the marking ink

will run.

Footnote 396:

Nitrate of Silver is commonly called an Escharotic. This, however,

gives no just idea of the properties of this valuable article, or of

the uses to which it may be applied. As a local application in cases

of external inflammation, punctured wounds, and ulcers, I have found

it a remedy of surpassing utility. It is to Mr. Higginbottom that we

are indebted for the full developement of this subject.—See “An Essay

on the use of Nitrate of Silver, in the cure of Inflammation, Wounds,

and Ulcers.” _Ed._

Footnote 397:

Horse-radish; horse-mint; bull-rush; &c. These epithets are Grecisms;

ιππος and βους, i. e. horse and bull, when prefixed to any word,

signified no more than great; thus the great Dock, Hippo-lapathum, and

the horse of Alexander from the size of his head was named Bucephalus.

Footnote 398:

An infusion of horse-radish is a very ancient remedy in disorders of

the stomach. In Paulus Ægineta we shall find a letter written by

Carytius Antigonus, in which it is highly recommended for such a

purpose.

Footnote 399:

The chemist may satisfy himself of this fact by heating some arsenious

acid on a piece of platinum foil, and alternately raising and

depressing it into the blue flame of the spirit, when corresponding

changes in odour will take place.

Footnote 400:

It will probably afford a satisfactory explanation of the circumstance

mentioned by Dr. Percival, that the workmen who solder silver

filligree with an arsenical alloy, are never affected by the fumes.

Dr. Percival does not appear to have been in the least aware of the

probable reason of this fact; he says, “This solder is melted by the

flame of a lamp directed by a blow-pipe; the greatest part of the

arsenic is evaporated by the blast and flame, and some part also of

the rest of the solder, and yet the men appear to enjoy as good

health, and to live as long as other artists! Amongst other examples

of the truth of this observation, I lately saw in the manufactory at

the Soho at Birmingham, a man of more than fifty years of age, who had

soldered silver filligree for thirty-five years, and had regularly,

during that period, passed from eight to ten hours daily in his

occupation, and yet he was fat, strong, active, cheerful, and of a

complexion by no means sickly; neither he nor his brother artists use

any means to counteract the effect of their trade.” Dr. Rotheram, in a

letter to Dr. Percival, comments upon this fact, and says, “how far

the fluxes used in soldering the filligree may fix the parts of the

arsenic, or from what cause these workmen might escape, I dare not

say, but I should notwithstanding strongly suspect the fumes of this

very volatile and caustic mineral to be very prejudicial.”—I have

shewn above that arsenious acid is readily decomposed when heated in

contact with an oxidable metal, and I apprehend that this fact will

explain the reason why the fumes of the alloy in question are disarmed

of their virulence.

In my work on Medical Jurisprudence, (Vol. ii. p. 216) the reader will

Footnote 402:

PLUNKETT’S OINTMENT, consists of arsenious acid, sulphur, and the

powdered flowers of the Ranunculus Flammula, and Cotula Fœtida,

levigated and made into a paste with the white of an egg, and applied,

on a piece of pig’s bladder, to the surface of the cancer.

PATE ARSENICALE. This favourite remedy of the French surgeons consists

of 70 parts of cinnabar, 22 of sanguis draconis, and 8 of arsenious

acid, made into paste with saliva, at the time of applying it. This

combination, observes a periodical writer, is similar, with the

exception of the ashes of the soles of old shoes, to that recommended

by Father Cosmo under the name of “Pulvis Anti-carcinomatosa.”

DAVIDSON’S REMEDY FOR CANCER, arsenious acid, and powdered hemlock.

Footnote 403:

In the Journal de Medicine, the following case of a woman is related

who was killed by her husband having insinuated powdered arsenic into

the vagina, at the moment of enjoying the conjugal rites. “A woman at

Leneux, department de l’Ourthe, aged 40, having died after a short

illness, attended with considerable tumefaction of the genital parts,

uterine hemorrhage, vomiting, and purging, the body was inspected by

order of the mayor, when the surgeons reported that they found the

vulva in a state of gangrene, the abdomen much distended with air, and

the intestines inflamed and gangrenous. The culprit was arrested,

convicted, and executed.” In the Acts of the Society of Medicine of

Copenhagen, a similar crime is recorded, committed also by a peasant;

in this latter case, although some small pieces of arsenic were found

within the vagina, yet, some doubting the possibility of this species

of poisoning, the magistrates consulted the College of Medicine of

Copenhagen, who decided the question in the affirmative, by

instituting a series of experiments upon horses.

SINGLETON’S EYE SALVE, OR GOLDEN OINTMENT. Under this name is sold a

preparation which consists of sulphuret of arsenic (orpiment) with

lard, or spermaceti ointment. The Unguentum Hydrargyri Nitrico Oxydi

of the London College is also sold under the same title.

DELCROIX’S POUDRE SUBTIL, “for removing superfluous hair in less than

ten minutes.”! This fashionable depilatory appears upon examination to

consist of Quick-lime and Sulphuret of Arsenic, with some vegetable

powder. It is, however, so unequally mixed, that in submitting it to

analysis, no two portions afforded the same results. It can scarcely

be necessary to state, that such a composition is incapable of

fulfilling the intention for which it is so confidently vended.

In Paris, arsenic forms the basis of several blistering cerates. Such

applications cannot be safe.

Footnote 404:

This substance may be considered as consisting of charcoal, in a state

of extremely minute division, and the sub-carbonate of potass. It is

prepared by deflagrating, in a crucible, two parts of Super-tartrate

of Potass with one part of Nitrate of Potass.

Footnote 405:

In order to close the end of the tube, where a blow-pipe is not to be

procured, the end is to be placed in a common fire, until it is

completely softened, and a pair of small tongs being at the same time

made red hot, the tube is to be withdrawn from the fire, and then

heated and pinched by the tongs, and at the same time bent up at an

acute angle, so as to be brought parallel to the body of the tube. The

tube is then to be heated a second time, and being again firmly

pinched by the hot tongs, the end will be found to be completely

impervious. Where a glass is not at hand Mr. R. Phillips says a common

draught phial may be made to answer the purpose, especially a _ten

drachm_ phial, for it is long in proportion to its diameter. In using

it, however, care must be taken that the suspected powder and black

flux do not reach the bottom, for, on account of its thickness, it

will readily break on the application of heat. The phial must

therefore be heated laterally by means of a spirit lamp.

Footnote 406:

Dr. Bostock has informed us that the best proportions for this coating

are one part of common pipe clay, to three parts of fine sand; which

are to be well kneaded together, and reduced to such a state of

tenacity that the lute will readily adhere to the tube, and its

different parts unite, without forming a visible seam, (Edinb. Med. &

Surg. Journ. April, 1809.)

Footnote 407:

Should the operator be unable to procure a spirit lamp, a very

convenient substitute may be provided in the following manner. Let a

piece of tin plate, about an inch long, be coiled up into a cylinder

of about ⅜ths of an inch in diameter, and, if the edges be well

hammered, it is not necessary to use solder. Perforate a cork,

previously fitted to a phial, and put a cotton wick through the short

tin tube, and the tube through the cork. The lamp is now complete, and

will afford a strong flame, taking care of course not to prevent the

rise of the spirit by fitting the cork too closely.

Footnote 408:

In the celebrated case of Kesler, who was tried in the state of

New-York some few years ago, for having poisoned his wife with

arsenic, this very question was agitated, and gave rise to much

learned controversy. The physicians originally called to examine the

body of the deceased, found, on dissection, the stomach and intestines

highly inflamed, and on the inner surface of the stomach, particles of

a vitreous appearance. These particles were subjected to various

chemical tests, all of which very strikingly concurred in confirming

the suspicion that they were arsenic. Upon this, in connexion with the

other testimony adduced in the case, the prisoner was found guilty and

condemned to death. The minutes of the trial were transmitted by the

presiding judge (Yates) to Governor Clinton, who submitted the

professional part of them to Dr. M‘Nevin of New-York, for his opinion

in relation to it. Thus called upon, Dr. M. seems to have considered

that his only duty was to find fault. Objections were accordingly

raised against every test hitherto employed by the best chemists for

the detection of arsenic. They were all pronounced to be uncertain,

and “_the only thing to be relied on_,” according to him, was “_the

exhibition of the metal itself in its metallic lustre and state_.” In

consequence of this difference of opinion, the execution of Kesler was

suspended by the Governor, and the whole case referred by him to the

Legislature. That distinguished body appointed a committee to

investigate the business, and the result was that the original verdict

of the jury was confirmed by the Legislature, and the criminal was

executed. It must furnish a source of the purest gratification to the

medical witnesses concerned in this case, to find their opinions so

unequivocally and so justly confirmed by an authority so high as Dr.

Paris. For a detailed account of this trial we refer to Beck’s Medical

Jurisprudence, vol. 2, p. 239.—_Ed._

Footnote 409:

If any trifling opacity occur in a simple solution of arsenic, when

assayed by the nitrate of silver, it may be considered as the effects

of some casual impurities; this is further demonstrated by bringing

over the surface of the arsenical liquid, a piece of blotting paper,

or a stopper, moistened with a solution of ammonia, when there will

instantly form a copious yellow precipitate of arsenite of silver. If

this experiment be performed on a surface of glass, laid over white

paper, the result is very striking and beautiful.

Footnote 410:

Annals of Philosophy, vol. x, p. 60.

Footnote 411:

London Medical and Physical Journal, January, 1818.

Footnote 412:

In Wine and Porter, the solvent is probably Tartaric acid, for the

Arsenite of Silver is soluble in this as well as in the acetic and

nitric acids. In Tea the solvent would appear to be Tannin. The

Arsenite of Silver is likewise dissolved by the Tartaric acid, and

also, but not so readily, by the Citric and Acetic acids.

Footnote 413:

This opinion has lately received ample confirmation from the

experiments of Dr. Christison, (Edinb. Med. and Surg. Journal, July,

1824) who has shewn that the process of Orfila is objectionable on the

three following grounds, viz.

1st. The colour is very seldom so entirely destroyed but that the

precipitates produced by some of the tests still deviate to a certain

degree from their characteristic tints; and although the colour of the

fluid be even destroyed entirely, it often re-appears in the

precipitates.

2d. Although the Chlorine destroys the colour, it does not also take

from the fluid its solvent action on the arsenical precipitates.

3d. In fluids decolorized by Chlorine, and containing no Arsenic, some

of the tests produce precipitates, not only precisely the same with

those which they cause in the decolorized solutions of Arsenic, but

likewise very similar in appearance to those caused in a pure aqueous

solution of Arsenic.

Footnote 414:

The experiments by which I ascertained this fact were made soon after

the publication of Mr. Phillips’s paper, and long before I saw Dr.

Christison’s communication in the Edinburgh Journal. I merely mention

this circumstance to add greater weight to the experimental evidence,

for when different persons arrive at the same conclusion without any

communication with each other, the strongest possible testimony is

afforded. I may also add that my suspicions were raised to the

probability of the fact by a knowledge of the action of charcoal upon

lime water. In a philosophical point of view the fact is one of great

interest; it seems to connect the phenomena of mechanical and chemical

attraction. We have evidently a body removed from the state of

solution by mechanical means.

Footnote 415:

The following is the formula for its preparation. Dissolve ten grains

of lunar caustic in ten times its weight of distilled water, to this

add, _guttatim_, liquid ammonia, until a precipitate is formed:

continue cautiously to add the ammonia, repeatedly agitating the

mixture until the precipitate is nearly redissolved. The object of

allowing a small portion to remain undissolved is to guard against an

excess of ammonia. Wherever the test is used, the liquid to which it

is added ought to be quite cold.

Footnote 416:

This is very important, for an excess of ammonia redissolves the

yellow precipitate, and therefore defeats the object of the test. The

fixed alkalies, in excess, have not such a property.

Footnote 417:

The great impression made upon the public mind in Cornwall, by the

above trial, produced a disposition to regard the cause of every

sudden death with more than usual jealousy. See a Report of this trial

in the Appendix of our work on Medical Jurisprudence.

Footnote 418:

In consequence of a report having arisen that a young woman had died

after an illness of forty-eight hours, and been hastily buried at

Madron, the magistrates of that district issued their warrant for the

disinterment of the body, and requested my attendance at the

examination. It appeared upon dissection that the immediate cause of

death had been inflammation of the intestines; the stomach was found

to contain a considerable portion of liquid, which was carefully

collected and examined; no solid matter could be discovered in it. It

appeared to consist principally of the remains of a quantity of

penny-royal tea, which had been the last thing administered to the

deceased. This was divided into several portions, and placed in

separate wine glasses, and submitted, in the presence of the sheriff

and other gentlemen, to a series of experiments, amongst which the

following may be particularized, as bearing upon the question at

issue.

1st. A few drops of a solution of sub-carbonate of potass were added

to the liquid, in one of the glasses, when its colour, which was

before of a light hazel, was instantly deepened into a reddish yellow;

the sulphate of copper was then applied, when a precipitate fell down,

which every one present immediately pronounced to be of a _vivid

green_ hue, but in pouring off the supernatant liquid, and

transferring the precipitate upon white paper, it assumed a blue

colour, without the least tinge of green; the explanation of the

phenomenon, and the fallacy to which it gave rise, was obvious: the

yellow colour, imparted to the liquid by the alkali, was the effect of

that body upon vegetable extract, and will generally take place on

adding it to the infusions of vegetable substances.

2nd. To another portion of the liquid, the ammoniaco-nitrate of silver

was added; a slight turbidness arose, but no yellow precipitate

occurred.

3rd. After adding a fixed alkali, the surface of the liquid was

touched with a stick of lunar caustic, but no yellow precipitate was

produced.

4th. The liquid was next assayed in a watch-glass, for a phosphate of

soda, by endeavouring to form a triple salt with magnesia and ammonia,

as suggested by Dr. Wollaston; the result proved that phosphate of

soda was not present. It is unnecessary to pursue the relation of the

experiments; I conceive that sufficient evidence has been adduced to

establish the truth of the explanation. I have frequently repeated the

first experiment, substituting for the gastric infusion, a decoction

of onions, and with similar results.

Footnote 419:

This explanation applies equally to the objection lately advanced by

Dr. Porter, of the University of South Carolina, who in observing on

the tests for arsenic, remarks, that an appearance similar to

Scheele’s Green, is produced by the carbonate of potass when added to

a solution of copper containing coffee, but without arsenic, more

striking than if a weak solution of arsenic be used. Silliman’s

Journal, iii. 365.

Footnote 420:

Annals of Philosophy, New Series, No. III. for March, 1821.

Footnote 421:

The habitudes of arsenious acid with the nitrates were first observed

by Kunkel; nitrous vapour is disengaged, part of the oxygen being

absorbed by the arsenious acid, by which an arsenite of potass is

formed.

Footnote 422:

Dr. Bostock confesses that where less than three-fourths of a grain

were used, he could not say that the metallic crust was clearly

perceptible; and Dr. Black considered that one grain was the smallest

quantity which could be distinctly recognised by such a process. Dr.

Jaeger (Dissertatio Inauguralis, Stuttgard, 1808) also observes, that

he has been enabled to recognise the tenth of a grain of arsenious

acid, although mixed with sugar, by its odour, when thrown upon

burning coals! I must be allowed to question this fact; Dr. Jaeger, no

doubt, believed that he recognised the alliaceous odour, but it must

have been the effect of imagination. Dr. Bostock observes that, if

Arsenic be mixed with either an animal or vegetable substance, the

smoke and smell arising from those bodies, when heated, will

altogether prevent our recognising its odour. He found that when a

quantity of Arsenic was mixed with an equal weight of flour, and

placed upon iron at a low red heat, so as not to cause the flour to

inflame, the suffocating smoke that arose from the latter could be

alone perceived; nor was it possible to discover that any thing had

been mixed with it (Edinb. Med. Journal.) This objection of Dr.

Bostock is true in fact, although it admits of a different

explanation, for at a low temperature the Arsenious acid would be

volatilized without decomposition; in which case no alliaceous odour

can be developed. Dr. Traill has lately asserted (Annals of

Philosophy, Feb. 1824) that he has recognised the alliaceous odour

during the volatilization of 1/78th of a grain of the metal. I do not

question the truth of this assertion, but there must have been an

address in the manipulation which we cannot expect to find in ordinary

experimenters.

Footnote 423:

Assafœtida was used by the ancients as a condiment, under the name of

σιλφὶον, _Laserpitium_, (Pliny); and according to Kempfer, the

Persians use it for the same purpose. The Arabian writers on the

materia medica class this article among their Mobehyat

(_Aphrodisiaca_). The term Assafœtida is derived from the monks of the

Salernian school; some of the writers of the middle ages call it Opium

Cyrenaicum, i. e. the Juice from Cyrene.

“Or have we eaten of the insane root,

That takes the reason prisoner.”

_Macbeth._

The Belladonna is supposed by Sauvage to be the plant that produced

such extraordinary effects upon the Roman Soldiers during their

retreat, under the command of Anthony, from the Parthians, when they

are said to have “suffered great distress for want of provisions, and

were urged to eat unknown plants; among others they met with a herb

that was mortal: he that had eaten of it lost his memory and his

senses, and employed himself wholly in turning about all the stones he

could find, and after vomiting up bile, fell down dead.” (Plutarch’s

Life of Anthony.) The Scotch historian Buchannan relates, “that the

Scots mixed a quantity of the juice of the Belladonna (_Solanum

Somniferum_) with the bread and drink which by their truce they were

to supply the Danes with, which so intoxicated them that the Scots

killed the greater part of Sweno’s army.”

affection should recover during the use of such a remedy, I should

certainly designate it as a lucky Escape, rather than as a skilful

Cure.

The gas which arises from the combustion of mineral coal will produce

the same effect. It is related of a lady of fashion, who had

incautiously seated herself too near the fire, at a quadrille party,

that her countenance changed on a sudden from a delicate white to a

dark tawney, as though by magic. The surprise and confusion of the

whole party had such an effect upon the disfigured _fair one_, that

she was actually dying from apprehension, when the physician dispelled

their fears by informing his patient that nothing more was necessary

than for her to abstain from the use of mineral cosmetics, and to

trust in future to those charms which Nature had bestowed upon her.
