When used as a bath, the mixed acid should be added to the water until it tastes as sour as weak vinegar. Incomp. Oxides, earths, alkalies, the sulphurets, and the acetates of potassa and of lead. AClDUM PHOSPHORiCUM DILUTUM. L. Diluted Phosphoric Acid. (Phosphori 3vj.; Acidi Nitrici t'Siv.; Aquce distillatce fjviij.) Comp. Phosphorus 2 eq.=31-4 ; oxygen 5 eq.=40 ; equiv. 71'4. Spec. grav. 1-064. Prop. Colourless, inodorous, strongly acid, fluid. Oper. Tonic. Uses. In disposition to urinary deposition of the phosphate of lime ; in general debility. Dose. Tllxx. to f3j. Tests. A fluid ounce saturates 132 grains of crystallized carbonate of soda : a precip. by chloride of barium insoluble in nitric acid indicates sulph. acid. ACiDUM PYROLIGNEUM. E. Proligneous Acid, (from destructive distillation of wood.) Comp. and Prop. The same as those of acetic acid ; spec grav. 1-034. 100 minims should neutralize 53 grs. of carbonate of soda. Use. The same as diluted acetic acid. ACIDUM SUCCINIC UM. D. Succinic Acid. Sal Succini. Comp. Carbon 4 eq. = 24-48-rhydrogen 2 eq.=2+oxygen 3 eq.=24. eq. 50-48. Chemical symbol, C4 H2 O3 ; (obtained from amber.) Prop. Taste sour ; crystals four sided rhomboidal plates, white, trans- parent ; soluble in hot water, and hot alcohol; volatile. Incomp. Mucilage, oils. This acid is never, or very rarely used in medicine. ACIDUM SULPHURIC UM. L. Acidum Sulphuricum purum. E. D. Acidum Sulphuricum venale. D. Sulphuric Acid. Acidum vitri- olicum. Comp. Of sulphur 1 eq. = 16-1+oxygen 3 eq.=24, eq. 40*1, and water; or acid 81-6 ; water 18-4. Chemical symbol, S3. Prop. Inodorous; strong acid taste; corrosive; fluidity dense, ap- parently oily; transparent, colourless. Spec. grav. 1-845. (1-850 ad 1000, d.) It has a powerful attraction for water. Oper. Escharotic, stimulant, rubefacient. Use. In local pains, in the form of an ointment made of lard f5jsul- phuric acid 3j.; and in scabies, with 3ss. of the acid to lard 3j. Tests. Distilled water should cause no muddiness ; solution of sulphate of iron no reddening at the point of contact. Off. Prep. Used in preparing Acidum Hydrochloricum, Acid. Hydrocy- anicum, Acid.

Introduce it into a small plain retort, containing a few slips of platinum foil, and passing the beak of the retort into a Florence flask, which is to be used as a receiver, with the aid of a small charcoal fire, or gas lamp, distil over one tenth of the acid. This being rejected, and a fresh receiver of the same kind connected with the retort, let the dis- tillation be resumed, and continued until no more than about an ounce of liquid remains behind. The distilled product should now be trans- ferred to, and preserved in a well stopped bottle. The sp. gr. of this acid is 1-846. Prop, and Med. Use. The snme as the common acid.
