![Grey Oxide of Mercury. Oxidum hydrargyri cinerei. Sub-proto-nitrate of mercury and ammonia. Hahnemann's solu- ble mercury. This oxide is obtained by pouring liquid ammonia into a solution of pure proto-nitrate of mercury. Th. E. Both these oxides are very seldom used; however, German practitioners still exhibit them in some cases in which the employment of mercury, in a state of great division, is indi- cated. They think that these preparations do not provoke saliva- tion so easily. However, as their composition is apt to vary, so their effects are very uncertain. D. & M. of Adm. Internally. Gr. $ to gr. v. a day, in pills. Hahnemann's pills, Paris H. (Gray oxide of mercury, gj.5 gum Arabic and sugar, aa. gss.; for 32 pills.) Dose, from No. iij. to iv. a day. Externally. Unguentum oxidi hydrargyri cinerei, U. S., E. (Black oxide of mercury, 1; axungia, 3.) In frictions, £ss. to 5j. Proto-nitrate op Mercury. Hydrargyri proto-nitras. This salt is always the product of art. P. P. It is in the form of prismatic crystals, white, of an acrid and styptic taste, inodorous, and very heavy. C. P. Proto-nitrate of mercury is composed of nitric acid, 100, and protoxide of mercury, 388.73. It generally reddens litmus. Dissolved in water, it is decomposed and forms a super- proto-nitrate remaining in solution, and an insoluble sub-proto- nitrate, which precipitates in the form of a greenish-yellow pow- der. Heated, it changes to a deutoxide, which is reduced if the heat be sufficiently high. Prep. Dissolve 200 parts of mercury in 180 parts of nitric acid at 25°. When no more nitrous vapours are disengaged, add 100 parts of warm distilled water, and subject the liquor to a slight ebullition. Then, decant the liquor, and soon after, crys- tals will begin to form. By evaporating the mother-waters, purer crystals will be obtained. The purity of the proto-nitrate of mercury may be ascertained by the following characters. Its so- lution is entirely decomposed by the muriates of potassa or soda, and the filtered liquor does not form a yellow precipitate with potassa, or a black one with hydro-sulphuric acid. Th. E. It is very seldom employed internally, except in con- junction with syrup, as an anti-syphilitic. Externally, it is used as a stimulant, detersive, and escharotic. the blue pill, prepared as it is, in the ordinary way, by trituration, is more cer- tain, efficient, and regular in its operation. Haifa grain is quite a sufficient dose to be taken at bed-time, and probably one-fourth of a grain might answer the purpose, as this quantity appears to be equal in strength to three or four grains of the blue mass.
