    one-half ounces; distilled water, one ounce, to be used freely with an eye-cup. HUMULUS. Hops. The strobiles of Humulus lupulus. The efficacy of hops as a sedative depends on the presence of lupulin, which consists in turn of a volatile oil associated with a resin. Fresh hops are always much richer in lupulin than old stock. General Surgery.—Hops are employed in the form of poultices, and have long enjoyed a reputation for relieving pain. The poultice is best prepared by moistening with hot water the -hops contained in a gauze bag, the desired size and shape, constituting what is known in domestic medicine as the hop pillow. A hop poultice may be employed, with great advantage over the heavier flaxseed poultice, in Abdominal Inflam- mations. It should be covered with waxed paper to retain the moisture. It is also indicated in Orchitis, either due to mumps or specific inflam- mation. Applied to the penis in Gonorrhcea it will assist in preventing Chordee. Diseases of the Throat, etc.—Hops have long been used as a domestic remedy in Inflammatory Swellings of the upper respira- tory passages. A little weak vinegar poured upon a pillow containing the hops may be placed near the patient's face and the fumes inhaled. Lupulin can be used in a similar manner. It is often employed in the first stage of Acute Coryza. As an inhalant for Acute Laryngitis the following is recommended: R. Ext. lupulini, one ounce; sodii ( carbonat. exsiccat., one scruple; aquce, one pint. In Acute Laryn- j cms, if rapidly progressive and accompanied with great pain, hot inhala- tions containing five grains of lupulin to the ounce of water are strongly recommended by W. E. Casselberry. Diseases of the Eye.—A small bag of thin flannel, containing hop leaves and dipped in a hot infusion of this herb, forms a convenient means of applying moist heat in ophthalmic practice. HYDRARGYRI CHLORIDUM CORROSIVUM. Corrosive Chloride j of Mercury. Corrosive Sublimate. Mercuric Chloride. Corrosive sublimate is in heavy, colorless, rhombic crystals or crystalline masses, permanent in the air, odorless, having an acrid and persistent metallic taste and acid reaction ; soluble in sixteen parts of water and in three parls of alcohol at 15° C. (59° F.), in two parts of boiling water, in one and two-tenths parts of boiling alcohol, and in four parts of ether. (U. S. P.) ' The addition of equivalent weights of chloride of ammonia or chloride of sodium renders corrosive sublimate, because of the formation of a double salt, much more quickly and freely soluble than it is alone. The double chlorfde of mercury and ammonia is called ''sal alembroth.
