Antimonial AEThi-ops. Dr. Cockburn, in his Treatise on the Gonorrhoea, directs us to melt equal parts of antimony and sea salt in a crucible, and separate the scoriae, then to rub equal parts of the regulus made in this manner and mercury together, till they are incorporated. He extols it in cutaneous diseases, glandular obstructions, and many other chronical diseases: a few grains are given at first, and the quantity is increased as the patient can bear it. Malouin, in his Chemistry, gives various processes for uniting antimony with mercury, some of which are more speedy, and others more perfect in forming this combination; but all the preparations where the crude antimony is employed are inert, in consequence of the sulphur it contains. The Pillulae AEthiopicae, taken from a former edition of the Edinburgh Dispensatory, are now omitted in the Pharmacopoeia of both colleges.

-------------martialis, martial AEthiops. Put filings of steel into an unglazed earthen vessel, with water enough to rise four inches above the filings; the whole is to be stirred every day, and more water supplied as that in the vessel exhales, so that the filings remain always covered; continue this process till they are reduced to a powder of an inky blackness. This medicine seems never to have attained the notice of physicians, though it may probaby be an useful one. The iron is evidently oxygenated by the decomposition of the water, and it may be recollected, that in Griffith's medicine it experiences a similar change.

-------------mineralis. Now called Hydrargyrus cum

Sulphure, Lond. Ph. 1788. AEthiops, so called from its colour. Ethiops mineral is prepared by uniting equal parts of sulphur and mercury, with or without heat.

As sulphur so eminently abates the power of all the more active metals, this medicine is thought by many to be no further useful than as it is of efficacy in the stomach and bowels; others assert, that it enters the circulation, and is productive of very salutary effects. It is indeed possible, that a portion of the mercury may be separated from the sulphur, during the passage of the aethiops through the body. The dose is from gr. v. to 3 ss. It is equally useful with the cinnab. antimonii for fumigating venereal ulcers: and, like the cinnabar, it is hard to say that it is useful in any other way. In the present form with a double proportion of mercury it may be more active.

-------------vegetabilis. Vegetable AEthiops. By burning the sea-wrack in the open air, it is reduced into a black powder, and is then called vegetable aehiops. The soap-boilers call this kelp. The best is from Scotland. From Aethiops Antimonialis 223 to is given twice a day to remove scrofulous swellings.

-------------jovialis, is mentioned by Gmelin as useful in destroying taeniae. It consists of equal parts of tin, mercury, and sulphur; but is probably a medicine of little value, as tin acts mechanically.

----------------- Antipthysicus, Antirheumatics, Diureticus, and purgans, are denominated from their colour, and consist of mercury, with the Peruvian balsam; with gum guaiacum; with juniper gum; and with manna or jalap. These combinations are wholly unknown in this country, and perhaps scarcely deserve to be known.

-------------albus. See Mercurius alkalizatus.

- - - mercurii per se, is a simple oxyde of mercury, prepared by trituration, with or without mucilage. It has been given in venereal affections, in inflammations of the liver, and intermittents; and seems to have been at one time a favourite with the German physicians.
