That which next became fashionable, as having the greatest supposed resemblance, in its operation, to the celebrated fever-powder, was tartar emetic. It is prepared by boiling equal quantities of washed crocus of antimony and crystals of tartar in water. This, as being soluble in liquids, is said to be less precarious in its effects than the other solid preparations; yet the strength of it greatly depends upon the manner of conducting the process, for some of the tartar, in the ordinary method, will be apt to shoot by itself, retaining little of the crocus. Some have therefore advised, as soon as the solution is filtered, to carry the evaporation much further than is usually done, if not to the total exhalation of the liquor[59]. Its effects, however, are uncertain, six or eight grains sometimes proving a mild emetic; though in other cases, I have seen half a grain operate so severely as to bring on violent convulsions, and Newman has known three or four grains prove mortal.
Fatal consequences have also happened from want of attention to the different methods of preparing this medicine. A Dutch physician, being accustomed to an emetic tartar made with salt of tartar, which was given in doses of ten, twelve, or fifteen grains, prescribed a like dose from a German shop, by which the patient vomited to death[60].
Kermes mineral, a preparation similar to golden sulphur of antimony, has been vended as a quack medicine in France and Germany, under the title of Mineral Centaury, Kermes or Alkermes Mineral, or Poudre des Chartreu, and in England by that of Wilson’s Panacæa, and Russel’s Powder.
The king of France was at length persuaded by M. Dodart, his first physician, to purchase it from M. La Ligerie, a surgeon at Paris, and it was made publick in the year 1720: but, like all other catholicons, has lost its consequence since the secret has been divulged, and the medicine found to be a well-known preparation described by Glauber,[61] and the elder Lemery.[62]
How long this medicine was used by the mystical chymists cannot be known, since they seldom communicated any of their processes excepting for a valuable consideration, and under the strictest obligation to secresy. But Cristopher Farnner, who was a humble retainer of Glauber’s, on the small stock of chymical knowledge which he had gleaned from him and from a servant whom he seduced to betray his master and discover his secrets, attempted to become his rival, and set the process for making the golden sulphur of antimony to sale, at the price of thirty rixdollars. Glauber, incensed at his treachery, published his own improved method of preparing this medicine, which he calls a Panacea of common antimony, and it has since under different names, and with some variation, been transcribed into most of the chymical books[63].
According to Geoffroy, as well as the earlier chymists, it was esteemed an universal medicine. It sometimes vomits, often purges, and generally operates by sweat and urine; in a word, says this celebrated writer, it promotes the feveral evacutions, according to the different channels by which nature may be disposed to throw of the vitiated humours.
It is recommended in the small-pox and measles, in obstinate autumnal intermittents, in spitting of blood, and other pulmonary complaints, in chronic diseases arising from obstructions in the bowels, in dropsies and in the bloody-flux. It is made by boiling antimony repeatedly in water, with a certain proportion of alcaline salt, and owes its virtues to a portion of regulus being rendered soluble in water[64].
But this manner of preparing it is condemned by Hoffman; who affirms, that the reguline or arsenical parts are not sufficiently sheathed by the sulphureous, as appears from many circumstances which he mentions, but especially from its violent emetic quality. He recommends a different process, by which he supposes the sulphur to be so blended with the reguline, or arsenical particles as to render it a mild and effectual diaphoretic.
The fate of antimony and its preparations has been as various as the reports concerning their efficacy are contradictory. They have been ranked among the wonders of the world, and their virtues extolled beyond all probability. They have again been proscribed as baneful, and prohibited under the severest penalties.
