    AciDTTM Srccraicuir. Acid, or Salt of Amher. Mix amber with its weight of sand, aud distil. Press the crystals in bibulous paper, and resublinie. Dose, gr. iv to xij. AciDUM SULPHUEICUM. Oil of Vitriol. Is made ou the large scale by conveying the vapours produced by the coui- bustiou ofsulphnr, or iron pyrites, mixed with the vapours of nitric acid (obtained by treating nitrate of potash or nitrate of soda with oil of vitriol) into leaden chambers contaiung a little water. 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. The commercial acid is liable to be contaminated with various impurities. B. sp. gr. 1-843. [Contains 96-8 per cent, by wt. of hydrated, or 79 of anhydrous, sulphuric acid. 50'6 grains neutralize 1000 graiu-measures volumetric solution of soda.] Antidotes.— Calcined magnesia, or hicarbonate of soda in milJc, at short in tervals. In the absence of these, chalk, soap and ivater, or the plaster from the ceiling. AciDUM SuLPnuRicuM (Pcjeum). B. 1861. Having added to sulpliuric acid of commerce f3x'j. sulphate of ammonia in powder 33-, introduce the mixture into a plain retort with a few slips of platinum foil, cover the upper p)iirt of the body of the retort with a sheet-iron hood, and distil over one tenth of the acid into a flask. Remove this flask, and reject its contents; and, having applied a fresh flask, continue the distillation till only a fluid ounce of liquid remains behind. Preserve the product in a stoppered bottle. E. If the commercial acid contain nitrous acid, heat f 5viij of it with between gr. x to -xv of sugar at a temperature not quite suflicicnt to boil the acid, till the dark colour produced shall have disappeared. Other impurities may be removed by distillation. [Professor Redwood prefers fragments of rock crystal to platinum, to prevent explosive bumpings. The operation re(]uires great caution. Arsenic and lead may be removed from the diluted acid by a small qnimtity of .sulphuret of barium. Por the metliod of making anhgdrous sidpburic acid, see the Druggists' Receipt Book. 'Yho fuming sul- phuric acid of Nordhauson is distilled i'rom dried sulphaU' of iron. I AciDni SuLrilUlucUM Dilutum. B. Sulphuric acid f.^vij.
