    red. cong. iij. Acidi sulph. diluti, Ammonice liq., Carbonis animalis purif. sing. q. s. s.) Comp. Carbon, oxygen, hydrogen, nitrogen. Prop. Whitish powder, inodorous, taste bitter, acrid, soluble in 150 times its weight of water at 60°, and 50 at 212°; alcohol and aether dissolve it readily; permanent in the air; with acids forms dry, gummy, bitter masses, which the alkalies decompose. Use. Externally counter-irritant: too poisonous to be used internally. ACONlTI FOLIUM ET RADIX. L. Aconitum napellus ; Radix, D. Aconitum, E. Aconite, or Monks-hood Leaves. (Aconitum na- pellus. Monk's-hood; Poly and. Trigyn. N. O. Ranunculacccs, Mountains of Germany and Siberia. 1L) Prop. Dried leaves inodorous, taste subacrid; bitterish ; fresh very acrid* Oper. Narcotic, sudorific, deobstruent. Use. In chronic rheumatism, scrofula, scirrhus, palsy, amaurosis, and venereal nodes. Dose. Gr. j. gradually increased to gr. v. twice or thrice a day. Off Prep.

Inodorous, insipid, soft, unctuous, white. Oper. Emollient. Use. In the formation of ointments, cerates, plasters, and liniments. Off. Prep. Emplast. Cantharidis, L. Unguentum Sabince, L.

Mass difficult to break, dry, not deliquescent, foliaceous, of a fine bluish-green colour ; taste salt: completely soluble in sulphuric acid, and in hydrochloric acid ; partially in water. Oper. Tonic, emetic, escharotic, detergent. « Use. Scarcely ever used internally; applied to the callous edges of sores, and to consume fungus, but now seldom used. It is sometimes used as a lotion, (gr. j. in rose or elder-flower water f3j.) in scorbutic ulcerations of the mouth, but it cannot be much recommended. Dose. As a tonic under gr. |; as an emetic from gr. j. to gr. ij. Off. Prep. Linimentum JEruginis* L. Unguentum Subacetatis Cupri, E. D. .ETHER. L. ^ther Sulphuricus D. E. (Spirit RectificOW). Acid. Sulph. Venal, f^viij. Calcis recensustce 3j. Mix the acid and ten ounces of the spirit in a glass matrass capable of holding a quart at least: and, without allowing the mixture to cool, connect the matrass with a Liebigconden- ser, and, applying a sufficient heat to maintain the liquid in brisk ebul- lition, commence the distillation. As it proceeds, admit gradually, through a glass tube traversing the cork of the matrass, the remainder of the spirit, regulating its influx so that the boiling liquid shall maintian a constant heat. And when the entire has been introduced, continue the application of the heat until the contents of the matrass become black, and show a tendency to froth over. (The tube through which the spirit enters should dip by its lower extremity, where its diameter is contracted, at least half an inch beneath the surface of the liquid in the matrass ; and the eduction pipe of the reservoir for the spirit, with v/hich the exterior extremity of the glass tube is connected, should be furnished with a stop-cock to regulate the descent of the spirit. This reservoir also should be placed at least three feet above the level of the boiling liquid.) The crude ether thus obtained is to be agitated with the pulverized quicklime, and then rectified, the distillation being continued as long as the product, on being well shaken, continues to have a specific gravity lower than 750. The resulting liquid should be
