    of the mass the following day a matter of easy performance. It is also of use in Pruritus and Neuralgia of the outer ear passage. It has been used pure in Chronic Nasal Catarrh. Rauchfuss recommends it as a topical application in Chronic Laryn- gitis OF Children. In the proportion of one part to eight it is often used in gargles and lotions. Preparations which contain glycerin should be slightly warmed before being used in atomizer or inhaler, since the diminished density of the glycerin under moderate heat increases the ease with which the mass can be distributed. A solution of glycerin in water, in the proportion of thirty-three per cent., is found a convenient one to use in many inhalants. Diluted glycerin slowly swallowed relieves the painful deglutition of Chronic Laryngitis. Diseases of the Eye.—Glycerin is considerably used in ophthalmic surgery as an excipient, particularly in glycerole of tannin {q. v.) ; it also enters into the composition of boroglyceride {q. v.). These preparations are valuable applications in Granular Ophthalmia and other forms of palpebral Conjunctivitis, and the hygroscopic action of the glycerin adds much to their efficiency, especially where the palpebral conjunctiva is cedematous. This same property unfits it for use, unless freely diluted in collyria, for acute general conjunctivitis. Glycerites. The Glycerite of Starch, Glycerilum Amyli (U. S. P.), is made by first rubbing and then healing together (below 144° C.—291° F.) one part of starch and nine parts of glycerin. It is an elegant vehicle for the application either of the contained glycerin or for the exhibition of other substances. Glyceritum vitelli (glycerite of yolk of egg) is also official, and is made by rubbing together forty-five parts of the yolk of egg and fifty-five parts of glycerin. This is also known as glyconin. In the British Pharmacopoeia, glycerinum acidi carbolici, glycerinum acidi gallici, glycerinum acidi tannici, glycerinum boracis, are official, and are all made of the strength of one ounce by weight of the medicaments to four fluidounces of glycerin, and two fluidounces of water. Glycerinum aluminis (one ounce of alum and five fluidounces of glycerin), glycerinum plumbi subacetatis (a solution of subacetate of lead in glycerin, being of about the strength of the official liquor plumbi subacetatis (Goulard's Extract), and glycerinum tragacantha; (one hundred and ten grains of traga- canth in a fluid ounce of glycerin) are also official in the Br. Ph. Glycerite of yolk of egg applied to the skin, forms a varnish which effectually prevents the action of air. It is unalterable. This prepara- tion has never been much used, but is likely to prove an agreeable substi- tute for greasy protective applications in Erysipelas, Fissured Nip- ples, etc. (See Ovum.) General Surgery.—Glycerite of carbolic acid is a convenient prepa- ration from which carbolized solutions can be made.
