It has been already stated, in a former part of this work, that the white of egg decomposes corrosive sublimate, by converting it into proto-chloride of mercury or calomel, and when given in sufficient quantity has succeeded as an antidote. According to Peschier the white of one egg is required to render four grains of the poison innocuous.* If this cannot be procured, linseed tea, barley- water, broth, or even plain water may be given; but oily sub- stances, olten had recourse to, are useless, and often injurious by impeding the action of other remedies. The secondary treatment must resemble that adopted in gastritis and enteritis; general and local bleeding, fomentations, warm bath, and in general the anti- phlogistic regimen. Salts of Mercury. The salts of mercury are generally distinguished by their nauseous, styptic taste. Those that are soluble in water give a black precipitate with alkaline hydro-sulphurets ; gallic acid gives a yellow precipitate, and when a plate of copper is introduced into them, metallic mercury is precipitated. They are volatalized by heat, and if they be mixed with carbonaceous, matter metallic mercury is obtained. Yellow Sub-Sulphate of Mercury, or Turbith Mineral. Sub-sulphas Hydrargyri Jlavus, Ph. E —This salt is prepared by boiling two parts of mercury in three of sulphuric acid to dryness, and throwing the white mass obtained in this manner into boiling water, after it has been reduced to powder. The yellow sub- sulphate is immediately thrown down, which must be washed repeatedly with distilled water and dried by a gentle heat. It * Corvisart’s Journal de Medicine, xxxviii. |>. 77.
