    1-5 or 1-6 per cent, of real acid. (Dr. Kane.) Scheele's Pi'ussic acid is frequently prescribed; but this name indicates no certain strength. (See Appendix 3.) Acidum Hydrocyanicum Vegetabile. Schrader. Essential oil of bitter almonds 5J> rectified spirit Jix, distilled water 3ix. [Dose, 2 to 3 drops, in sugared water.] Acidum Hydrosulphuricum aqua solutum. P. Pass a cur- rent of sulphuretted hydrogen gas (procured by acting on sul- phuret of iron by diluted sulphuric acid) through cold distilled water, till it ceases to be absorbed. Acidum Iodicum. M. Bourson. 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, dry place, till crystals form. Acidum Lacticum. To Ovj of milk add ^viij of bicarbonate of soda. Expose it to the air for some clays, till it becomes sour, and saturate it with more soda. Repeat this as often as it be- comes 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 con- centrate the clear solution by evaporation, till its density is about 1-215. Acidum Meconicum. Meconic acid. Mix £j meconate of lime (formed in making muriate of morphia by the E. process) with Oj of boiling water, and add ^ iij of muriatic acid; redissolve the crystals, which the liquor deposits in cooling, in the same quantity of water and acid, till they are freed from lime. Acidum Muriaticum. D. and E. See Acidum Hydrochloricum. Acidum Nitricum. L. Distilled from equal weights of dry nitre, and oil of vitriol. Sp. gr. 1-500. The commercial acid is usually from 1-38 to 1*40. Acidum Nitricum Purum. E. As the last; but the nitre is purified by two or more crystallizations, till its solution is no longer disturbed by nitrate of silver. The acid inay be rendered colourless by gently heating it in a retort. The commercial acid may be concentrated by distilling it with an equal measure of oil of vitriol, until two-thirds of the nitric acid are brought over. Mr. Redwood.
