The residue of bones which have been exposed to a red heat without the access of air. It consists of about 10 per cent, of char- coal and 90 per cent, of phosphate and carbonate of lime. The residue of bones which have been burned to a white ash in contact with the air constitutes os ustum or bone-ash. This consists principally of phosphate of lime, mixed with about 10 per cent, of carbonate of lime and a little fluoride of calcium and phosphate of magnesia. Carbo Animalis Puriflcatus is animal charcoal from which the earthy salts have been almost wholly removed. This is effected as follows: Mix hydrochloric acid (10 ozs.) with distilled water (1 pint), and add bone black in powder (16 ozs.), stirring occasionally. Digest at a moderate heat for two days, agitating from time to time; collect the undissolved charcoal on a calico filter, and wash with distilled water till what passes through gives scarcely any precipitate with nitrate of silver, showing absence of chlorides. Dry the charcoal, and then heat it to redness in a closely covered crucible. The animal charcoal thus purified is a black pulverulent substance, inodorous and almost tasteless; it absorbs gases and odours. Tincture of litmus diluted with twenty times its bulk of water, agitated with it and thrown upon a filter, passes through B
