    next day, remove and drain the crystals, and concentrate the residual liquor for more. Purify them by crystalliza- tion. Potato starch is economically substituted for sugar. Poisonous. Antidote: chalk, whiting, or magnesia. cCIDUM PuHospHoRIcUM Diturum. L. Mix nitric acid fZiv, with distilled water fZviij; put them into a glass re- tort placed in a sand bath, add 3vj of phosphorus, and apply heat till fZvj have distilled. Return these into the retort, and again distil f§vj, which are to be thrown away. Evaporate what remains in the retort in a platina capsule to f%ij; and add to the acid, when cooled, sufficient dis- tilled water to make up f3xx. [It contains about 10 per cent. of real P. acid. Sp. gr. 1°064; f3j requires for neutralization 132 grains of cr. carb. of soda. Dose, from mx to mxl, properly diluted. ] c1pUM PrussicuM, vel Borussicum. See Acidum Hydro- cyanicum. c1pUM PyrotrenEum. E. Diluted acetic acid procured by the destructive distillation of wood. Sp.-gr. 1:034. 100 grains neutralize 53 of carb. soda. Acidum Aceticum e lig’. venale, D. is rather stronger; density, 1°044. cIDUM SaccHarioum. Saccharic acid is obtained by accurately decomposing saccharate of barytes by sulphuric acid. c1ipuM Svuccrnicum. Acid, or Salt of Amber. Mix amber with its weight of sand, and distil. Press the crystals in bibulous paper, and resublime. Dose, gr. iv to xii. cipum Sunpuuricum. Oil of vitriol. It is made on a large scale by conveying the vapours produced by the com- bustion of sulphur mixed with an eighth part of nitre, into leaden chambers containing a little water: or sulphur is burned alone, and the vapours from nitre and sulphuric acid also conveyed into the chamber. The weak acid thus obtained is concentrated first in leaden boilers, then in platinum or glass retorts, till its density is not less than 1-840. It is also obtained from iron pyrites. The com- mercial acid is liable to be contaminated with various impurities. The London College does not direct its purification, but requires its density to be 1°843, that it be
