    Spiritus Vini Rectificatus. Prus. Ph., : Tenuior. L. and D., E., . . . . Alcohol faible. P., . Spiritus Tenuior. L. 1824, . •897 to -900 •920 •912 •923 •930 Spiritus J3theris Aromaticus. L. 1824. Elixir Vitrioli dulce. Cinnamon 3iij, cardamom $iss, long pepper Jj, ginger 3J, spirit of s. aether f^xvj. Macerate 14 days in a stopped bottle, and strain. Dose, f£ss to fjj. Spiritus ^Etheretjs Nitrosus. D. Put fjfvj of rectified spirit in a quart matrass, and connect this with a Liebig's condenser, whose further extremity is fitted loo/ely by a collar of tow into a thin 8-ounce phial. Add fgj of water to fgiij of pure nitric acid, and having introduced half the mixture into the matrass through a siphon safety-tube, close the mouth of this tube with a cork, and apply for a few moments a gentle heat, so as to cause a commencement of ebullition. When the action pro- duced has relaxed, introduce gradually the rest of the acid, so as to restore it. The action having ceased, agitate the distilled product with half its bulk of solution of ammonia, allow the mixture to rest for a few minutes, and having separated the su- pernatant ethereal liquid, mix fgiv of it with Oij fjij of rectified spirit, and preserve it in small strong and accurately stopped bottles. The condenser should be fed with ice-cold water, and . the phial surrounded by a mixture of 1 part of salt and 2 of pounded ice; or with a mixture of 8 parts sulphate of soda in small crystals, and 5 of muriatic acid. [The following process, founded on that of Liebig, is recommended by Mr. James Grant, in the PliarmaceuticalJoiirnal. Mix Jij of powdered starch with f^j of rectified spirit in a glass flask; to these add f|jj of nitric acid (sp. gr. 1*36), apply a gentle heat if neces- sary, until slight effervescence takes place, and pass the disen- gaged nitrous aether first into a washing bottle, then into f^ix of rectified spirit. It is desirable to ascertain whether the pro- duct be free from prussic acid, with which Liebig's nitrous aether is said to be contaminated. See page 23.] Spiritus .ZEthereus Oleosus. D. Mix Oiss of oil of vitriol with Oj of rectified spirit, in a glass matrass; connect this with a Liebig's condenser, apply heat, and distil till a black froth begins to rise. Separate the uppermost stratum of the distilled liquid, and having exposed it to the air for 24 hours, let the oil be transferred to a moist paper filter, and washed with a little cold water. Dissolve it in Oss of rectified spirit, mixed with
