g. TINCTURA MURIATIS FERRI, E. TINCTURA FERRI MURIATI, L. D. Tincture of muriate of iron. Tincture of iron.

The Edinburgh tincture is prepared by digesting three ounces of purified black oxide of iron in powder, and ten ounces of muriatic acid, with a gentle heat; then adding, after the powder is dissolved, as much alcohol as will make the whole liquor amount to two pounds and a half. The preparations of the other colleges do not materially differ from this. Dose from 10 to 20 drops, twice or thrice a day.

h. FERRUM TARTARISATUM, L. Tartarized iron. Tartarized iron.

Prepared by mixing one pound of iron filings, and two pounds of powdered crystals of tartar, into a thick mass with distilled water, exposing them to the air for eight days in a wide glass vessel, and then drying the matter in a fand bath, and grinding to a very fine powder. See CHEMISTRY, p. 671. Dose from 10 to 30 grains.

V.

History of Simple and Official Medicines

Prepared by digesting four ounces of the preceding, with a pint of proof spirit, and straining.

Used in similar cases with the tincture of muriate of iron, which is, however, to be preferred to it.

f. Tinctura Ferri acetati, D. Tincture of acetated iron.

Prepared by rubbing together in a glass mortar, acetated vegetable alkali, and vitriolated iron, of each an ounce, till the mass deliquesces, and then adding during the trituration two pounds of alcohol, and straining the solution.

A powerful astringent and tonic. Dose 20 or 30 drops.

The preparations of iron, given in a moderate dose, gradually raise the pulse, improve the colour of the face, and increase the alvine, urinary, and cuticular excretions. Their taking proper effect is denoted by fetid eructations and black stools.

These tonics are indicated chiefly in cases of premature discharges, or suppression of natural secretions or excretions, proceeding from a languor and sluggishness of the fluids, and general weakness of the solids. They are therefore useful in passive haemorrhages, in dyspepsia, hysteria, and chlorosis; in most of the cachexiae, and in cancerous affections, and in the general debility that often remains after acute diseases or excessive haemorrhages.

The preparations of iron, when given too largely, or improperly, produce headache, anxiety, heat of skin, and not unfrequently haemorrhages or vomiting, pains in the stomach, and spasms and pains in the bowels. They are improper wherever the circulation is already too quick, the solids too tense and rigid; and where there is any fribrition and spasmodic contractions of the vessels.

287. Cuprum, E. L. D. Copper. See Chemistry, p. 674.

975 Subacetate of copper.

SUBACETIS CUPRI, E. AERUGO. Subacetate of copper. Verdigris. See Chemistry, No 1995.

Employed chiefly as an escharotic, to destroy callous edges or fungous flesh, or as a stimulant to foul ulcers.

Official Preparations.

a. AERUGO PRÆPARATA, L: D. Prepared verdigris.

Prepared like other substances not soluble in water.

b. OXYMEL AERUGINIS, L. Oxymel of verdigris.

Prepared by dissolving one ounce of prepared verdigris in seven ounces of vinegar, straining through linen, and boiling with 14 ounces of clarified honey to a proper consistence.

Sometimes used as a detergent gargle to venereal ulcerations of the mouth and tonsils, but with much precaution. More generally employed, mixed with some stimulant ointment, as an external stimulant and escharotic.

c. UNGUENTUM SUBACETITIS CUPRI, E. Ointment of subacetate of copper.

Prepared by mixing 15 parts of resinous ointment, and one part of subacetate of copper.

d. LIQUOR CUPRI AMMONIATI, D. AQUA CUPRI AMMONIATI, L. AQUA SAPPHARINA. Water of ammoniated copper. Sapphire water.

Prepared by the Dublin college, by mixing four grains of prepared verdigris, and two scruples of sal ammoniac, with eight ounces of fresh made lime water, digesting for 24 hours, and pouring off the clear liquor.

Used as a stimulant and detergent lotion.

288. SULPHAS CUPRI, E. CUPRUM VITRIO-LATUM, D. VIIRIOLUM CERULEUM. Sulphate of copper. Vitriolated copper. Blue or Roman vitriol. Blue stone. See Chemistry, No 1972.

Sometimes given internally as an emetic, in the dose of from two to five grains, and as a tonic, a grain or two, several times a-day; but its internal use is dangerous. More frequently employed as an escharotic.

Official Preparations.

a. SOLUTIO SULPHATIS CUPRI COMPOSITA, E. A-QUA STYPICA. Compound solution of sulphate of copper. Stypic water.

Prepared by boiling three ounces of sulphate of copper, and the fame of sulphate of alumina, in two pounds of water, till they are dissolved; than adding one ounce and a half of diluted sulphuric acid to the liquor previously filtered.

Employed chiefly as a styptic for stopping superficial haemorrhages, or bleedings at the nose.

b. AMONIARETUM CUPRI, E. CUPRUM AMMONIA-TUM, D. Ammoniarett of copper. Ammoniated copper.

Prepared by the Edinburgh college, by rubbing two parts of the purest sulphate of copper with three parts of carbonate of ammonia carefully together, in a glass mortar, till the effervescence has entirely ceased, and they unite into a violet-coloured mass, which is to be wrapped up in blotting paper, and dried, first upon a chalk stone, and afterwards by a gentle heat, and put into a phial that is to be closely stopped.

Employed as a tonic and antispasmodic, chiefly in cases of epilepsy. Dose about half a grain or a grain, gradually increased to four or five grains, three or four times a-day.

c. PILULÆ AMONIARETI CUPRI, E. Pills of ammoniarett of copper.

Composed of 16 grains of ammoniarett of copper in fine powder, and four scruples of crumb of bread, beaten into a mass with a sufficient quantity of water or carbonate of ammonia, and immediately divided into 32 equal pills.

One or two of these pills is a moderate dose.

For an account of the ill effects arising from copper as a poison, and the means of detecting and obviating them, see Fothergill's Cautions concerning the Poisons of Lead and Copper, and Duncan's Difpenfatory.

289. ARGENTUM, E. L. D. Silver. See CHEMISTRY, p. 681.

Officinal Preparation.

a. NITRAS ARGENTI, E. ARGENTUM NITRATUM, L. D. CAUSTICUM LUNARE. Nitrate of silver. Nitrated silver. Lunar caustic.

Prepared by dissolving in a phial, with a gentle heat, four ounces of the purest silver flattened into plates, and cut into pieces, in eight ounces of diluted nitrous acid, mixed with four ounces of distilled water, and evaporating to a dry mass, which is to be put into a large crucible, and placed on a gentle fire, increased gradually till the mass flows like oil; then pouring it into iron pipes previously heated and anointed with tallow, and when cool, putting it into a glass vessel to be well stopped.

Employed chiefly as an echarotic, to destroy the callous edges of ulcers, warts, and other excrencences; but lately much recommended, and employed with some success, as a tonic in cases of epilepsy. It should be begun in very small doses, about one-eighth or one-fourth of a grain, diffused in distilled water, or made into a pill with crumbs of bread, gradually increasing the dose to a grain or more, twice or three times a-day.

CHAP. IV. Gaseous Substances.

290. GAS OXYGENUM. Oxygenous gas. Vital air.

On the nature and properties of this gas, see CHEMISTRY, No 341.

When air, with an increased proportion of oxygen, is respired, it acts as a powerful stimulus, increasing the circulation and animal heat, raising the spirits, and producing a temporary increase of vigour and activity, followed, however, in a short time, by corresponding languor and weariness. From its stimulating effects, the respiration of superoxygenated air has been much recommended in various cases of debility, as chlorosis, epilepsy, asthmatic and dropical affections; but it seems now falling into disuse, from a conviction that practitioners were too sanguine in their expectations.

See Alyon Essai sur les Proprietes Medicinales de l'Oxygene, 8vo. Ward Differt. Inaug. de Medicina Pneumatica, Edin. 1800. Hodges's Differt. Inaug. de Oxygenio, Edin. 1801; and the Practical Synopsis.

291. GAS AZOTI OXIDUM. OXIDUM NITROSUM. Gaseous oxide of azote. Nitrous oxide. See CHEMISTRY, p. 493, 494. where the nature and effects of this gas are detailed at sufficient length.

As the respiration of this gas is not followed by the depression and debility consequent on the application of most other stimuli, it promises fair to become a useful remedy in some cases of debility and atony of the vital powers; but it is not yet much employed except by way of philosophical experiment. See Davy's Researches on Nitrous Oxide.

292. GAS HYDROGENEUM. Hydrogen gas. Inflammable air. See CHEMISTRY, No 373, &c seq.

Hydrogen gas diluted with about ten times its quantity of atmospheric air, has been recommended in asthmatic complaints; but its success has not equalled the expectations of physicians.

293. GAS HYDROGENEUM CARBONATUM. Carbonated hydrogen gas. See CHEMISTRY, No 412.

This gas, which is so deleterious when respired in its pure state, has been strongly recommended when diluted with about 20 parts of atmospheric air, as a remedy in phthisis, in some cases of which it has evidently been of service, relieving the symptoms, and at least arresting the progress of the disease. It should, however, be employed with great caution, and at first largely diluted.

294. GAS ACIDUM CARBONICUM. Carbolic acid gas. Fixed air. See CHEMISTRY, No 595.

Besides the solution of this gas in water (see No 875.), used internally as a tonic and refrigerant, the gas itself, as evolved from fermenting substances, is a good stimulant or antiseptic application to foul ulcers and cancerous sores. The modification of this substance, which is contained in yeast or barns, has been much employed of late in typhus, but we believe with no material benefit.

295. CALORICUM. Caloric. Heat. See CHEMISTRY, Chap. iii.

It would be in vain for us here to attempt any account of the effects of heat on the human body, and these have been amply detailed, both by chemical and physiological writers. It acts as a powerful stimulus, and as such is often employed, especially in the form of warm and vapour baths, in various cases of debility and atony of the system. The effect and uses of the warm and vapour baths have been already mentioned under WATER, as have the effects and uses of the cold bath.

296. LUMEN. Light. See CHEMISTRY, Chap. ii. Light.

Besides its effect on the eye, in producing vision, light evidently acts as a general and powerful stimulus, raising the spirits, and increasing the vigour and activity of the body. See Ruh's Lectures on Animal Life.

297. ELECTRICITAS. Electricity.

Common electricity acts as a powerful stimulus on the system, in proportion to the degree of concentration in which it is applied. When applied under the form of a stream, or continued discharge of electric fluid, its effects are the most gentle; but in general, when applied in the form of sparks, it is more active, but its effects are more confined; and when applied by way of a shock, it acts very powerfully, producing an agitation of the muscles of the part through which the shock is discharged; and if the shock is violent, the whole body partakes of the agitation. Electricity Part IV.

History of Electricity has been found of service, chiefly in cases of Simple and paralyis, and of uterine obstruction dependent on debility.

For the mode of applying electricity to the body, under its various states, we must refer to Cavallo's Medical Electricity, and Cuthbertson's Practical Electricity and Galvanism.

298. GALVANISMUS. Galvanism.

This modification of electricity is found to have produced still greater effects on the human body, when applied under particular circumstances, into which we have not now room to enter. Much has of late been written on the efficacy of this powerful agent in the cure of various diseases, but like most other new remedies, its powers have been greatly overrated. It appears to have been most successful in cases of local paralyses, or nervous atony. In particular, it has in several instances relieved deafness, especially that species which seems to arise from torpor of the auditory nerve.

For the effects of galvanism on the body, and its application in medicine, see Wilkinson's Elements of Galvanism, vol. ii. p. 441.; Cuthbertson's Electricity and Galvanism; the Edinburgh Medical and Surgical Journal, &c.

ADDENDUM.

The following was omitted among the preparations of iron.

g. CARBONAS FERRI PRÆCIPITATUS, E. Precipitated carbonate of iron.

Prepared by decomposing a solution of sulphate of iron by a solution of carbonate of soda; washing and drying the precipitate.

Similar in its virtues to 961. Dose five to 30 grains.

The space allotted to this article was so small, and the time for preparing it so short, that it is, of necessity, much less full and complete than it might otherwise have been. As it was impossible, under such circumstances, to produce any thing like an original and complete treatise, the compiler has endeavoured to render as useful as possible the selection that he found it necessary to make, and to supply the unavoidable deficiencies by a reference to the most respectable works on the subject.
