    Pharmacopeeia, which is of a known and definite strength. — As prepared by different makers it has been found to con- tain from 3 to 5 per cent. of real acid. The following is — Scheele’s process:—Mix 3ij of Prussian blue with 3vj of red precipitate of mercury, and add 3vj of water. Boil for some minutes, constantly agitating; pour the whole on a filter, and wash the residuum on the filter with 3ij of hot water, which is to be added to the filtered liquor. Add to this 3jss of clean iron filings, and 3iij of sulphuric acid, shake well, and let it settle; then pour the clear liquor into a retort, and distil a fourth part into a receiver well luted and kept cold. ActpuM HyprocyaNIcuM VEGETABILE. SoHRADER. KEs- sential oi] of bitter almonds 3), rectified spirit ix, distilled water 3ix. Dose, 2 to 3 drops, in sugared water. AciDUM HyDRO-sULPHURICUM AQUA soLUTUM. P. Pass a current of sulphuretted hydrogen gas (procured by act- ing on sulphuret of iron by diluted sulphuric acid) through cold distilled water, till it ceases to be absorbed. Actpum Iopicum. M.Bovurson. Treat one part of iodine with four parts of strong nitric acid (sp. gr. 1:5) by the aid of a gentle heat. Evaporate to dryness, and leave the mass exposed to the air till it deliquesces. Then place it in a warm and dry place, till crystals form. Dose, 3 to 6 grains. Acipum Lactricum. To Ovj of milk add Sviij of bicarbonate of soda. Expose it to the air for some days, till it be- comes sour, and saturate it with more soda. Repeat this as often as it becomes acid. Boil, filter, evaporate to the consistence of syrup, and digest with alcohol. Filter the solution, and add sulphuric acid as long as it occasions a precipitate. Again filter, and concentrate the clear solu- tion, till its density is about 1:215. Dose, 5 grains, repeated. Acipum Merconicum. WMeconic acid. Mix 3j meconate of lime (formed in making muriate of morphia by the E. process) with Oj of boiling water, and add 3iij of muriatic acid; re dissolve the crystals, which the liquor deposits in cooling, in the same quantity of water and acid, till they are freed from lime.
