VAPOR ACIDI HYDEOCYANICI. Diluted Hydrocyanic Acid, 10 to 15 minims ; Cold Water, GO minims ; mix in a suitable apparatus, and let the vapour that arises be inhaled. Wot Official. ScJieele's Prussia Acid, now obsolete, was nearly three times the strength of that of the Pharmacopoeia. ACIDUM NITRICUM. NITEIC ACID. Syn. Azotic Acid. Colourless. Contains 60 per cent, of anhydrous Acid, N205, eq. 108, or 70 per cent, of real acid HN03, eq. 63. If it be poured upon copper filings, dense red fumes are formed. Test —Sp g 1-420. 90 grains by weight, mixed with half an ounce of distilled water, require for neutralization 1000 grain-measures of the volumetric solution of Soda. Evaporated, it leaves no residue. Diluted with six volumes of distilled water, it gives no precipitate with Chloride of Barium or Nitrate of Silver-indicating absence of Sulphuric and Hydrochloric Acids. 5 measures of Acid, sp. g. 1-500, and 2 of water mixed, condenses into 64 measures, and makes the sp. g. 1-420.
