    local irritation. Wax is one of the ingredients in making Lister's carbolized gauze, which is impregnated with crystallized carbolic acid I part common resin and white wax, of each 4 parts. (Cheyne, - Anti- septic Treatment of Wounds, p. 43-) We have used this gauze, but much prefer one from which the wax is omitted, which is a much softer and pleasanter dressing to deal with. It consists of castor-oil, i part; car- bolic acid, 2 parts; resin, 8 parts, and alcohol, 45 P^^ts. The gauze is saturated with this preparation, allowed to dry, and then packed in air-ticrht jars. A piece of wax should be in every general operating case,''as it is of use in preparing ligatures. At one time all silken or linen ligatures were thoroughly waxed before being applied to vessels, but at the present day the use of the catgut ligature has super- seded them almost entirely. All large ligatures for tying Piles or N^vi, etc., should be thoroughly waxed before using, which makes them much less'liable to slip in tying, and renders the knots more secure. A con- venient means of arresting Hemorrhage from the cut end of bone, especially the end of the tibia after an amputation of the leg, is to drive forcibly a small piece of wax, the size of a split pea, into the cancellated structure of the bone at the bleeding point. CERII OXALAS. Oxalate of Cerium. It is a white, granular powder, permanent in the air, odorless and tasteless, insoluble in water or alcohol, but soluble in hydrochloric acid. (U. S. P.) Diseases of the Nose, etc.—The oxalate of cerium can be used, according to F. H. Bosworth,in the form of a powder, in the proportion of twenty grains to the ounce of acacia in Chronic Catarrh of children. CETRARIA. Iceland Moss. The dried lichen, Cetraria Islandicar (Br. Ph.) The plant is without odor and has a slightly bitter taste. Iceland Moss contains a peculiar starch known as lichenin, a bitter principle, and other unimportant constituents. Lichenin is insoluble in cold water, but readily soluble in hot water. Boiling water dissolves out everything soluble in Ice- land Moss, and the solution gelatinizes on cooling. Iceland Moss is used as an ingredient of a throat lozenge. CHINOLINE. Quinoline. Leucoline. Chinoline is an alkaloid prepared by the destructive distillation of quinine or cincho- nine with potassium hydrate, and also, synthetically, by the action of sulphuric acid and glycerin upon nitro-benzol and aniline, or a mixture of these two latter substances. It is a colorless, strongly refractive, oily liquid, having a specific gravity of 1.081 at 10° C. (U. 1
