    tril in Acute Coryza. It gives temporary relief to the sense of disten- tion and heat The subnitrate of bismuth enters into the composition of Ferrier^s'snuff, in proportion of six drachms of bismuth, two drachms . of powdered acacia, and two grains of muriate of morphine. Of this quantity one-quarter to one-half may be used in twenty-four hours, or one part of the drug may be added to acacia, starch, lycopodium, or even Venetian talc (Trousseau). Combined with the yellow oxide of mercury, subnitrate of bismuth is useful in the form of an omtment in Eczema of the nostrils. In the treatment of Pharyngitis and Laryn- gitis accompanied with hypersecretion, subnitrate of bismuth is of the same value as in the treatment of Coryza. Whistler has suggested its use in the form of a pastille. It has been especially recommended in Chronic CEsophagitis ; one pastille can be taken every half hour. In the proportion of five grains to an ounce of rose water, to which a little glycerine has been added, subnitrate of bismuth is an agreeable mouth wash in Superficial Glossitis and in Aphtha. BISMUTHI TANNAS. Tannate of bismulh is prepared by triturating the moist hydrate from 44 parts of sub- nitrate of bismuth with 20 parts of tannic acid. After the mixture has stood an hour or two it is washed, and then dried at a genlle heat. The product consists of 53 per cent, bismuthous oxide and 47 per cent, of tannic acid. It is insoluble, and therefore, nearly tasteless. Diseases of the Nose, etc.—Tannate of bismuth is used by some French physicians as an astringent for the nasal mucous membrane. {Jour, de Med.de Paris, \d>go.) BISMUTHI TRINITRAS. Trinitrate of Bismuth. Bismuth Nitrate. A crystalline salt deposited from solutions of bismuth in nitric acid. The form in which it is usually used is that of the glycerite, made by dissolving sixty grains of crystallized nitrate of bismulh in one ounce by weight of glycerin without heat. It can be diluted with its own weight of water without precipitation, but larger quantities of water precipitate it. According to H. McNaughton Jones, the trinitrate of bismuth is an ingredient of Ferrier's snuff. BLEEDING. General Surgery.—In the pre-anaesthetic days of medical practice, in order to produce muscular relaxation, patients were bled up to the point of syncope before attempting the reduction of a dislocation. To-day bleeding is so seldom practiced that many physicians have never per- formed or even seen the operation of phlebotomy. Jurgensen, in his
