A solid, bluish-white, lamellated, veryductile metal, more laminable than capableof being drawn into wire, not very hard,fusible above the red heat, volatilizable,burning with a vivid flame, and acted onvery slightly by moist air. Its specific gra-vity is 7,1.
CHLORÜRET OF ZINC.
Murías seu Butyrum Zinci. (Niemann)
R. Pure Hydrochloric Acid, three ounces.
Throw shot-zinc gradually into it till itwill dissolve no more, then add
Water, three ounces.
Filter the liquor and evaporate it to dry-ness. It is astringent and emetic.
JÎTHEREOUS SOLUTION OF HYDROCHLO-RATE OF ZINC.
Mther Zinci. (Niemann ; Van Mons)
R. Dried Hydro-chlorate of Zinc,
half an ounce.Pure Alcohol, one ounce.
Sulphuric jEther, two ounces.
Decant at the end of a few days.
It is anti-spasmodic. — Dose, from four toeight drops, twice a day.
CYANURET OF ZINC.
Hydrocyanas Zinci. (Magendie ; Nie-mann)
R. Hydrocyanate of Potass, any quantity.Sulphate of Zinc, a sufficient quantity.
Having dissolved them, add the latter tothe former till no more precipitate is formed.Dry and calcine this at a dull red heat.
The product is a mixture of cyanuret ofzinc and of potassium. — It has been extolledin nervous cardialgía. — Dose, from thefourth of a grain to one grain and a half ina potion, to be taken by spoonfuls.
