2. Prepared for Pharmaceutical Purposes.
It may be obtained, as Van Mons hasrecommended, by precipitating hydrochlo-rate of lime with phosphate of soda, andwashing and drying the precipitate. Or,by treating liquids extracted from animalcharcoal and gelatine of bone ; by hydro-chloric acid, filtering, precipitating by po-tass, and washing and drying the precipi-tate which is formed. But the phosphatealready formed in the bones of animals ispreferred ; separating it from the animalmatter, with which it is combined in theproportion of twenty-seven per cent. Twomethods are described for this purpose :
1. Bones broken in pieces, any quantity.
Arrange them in a blast furnace (fotirneauh vent) with alternate layers of charcoal ;fill the intervals with saw-dust, and applythe fire. (Van Mons]
