    jection should be prepared when required. The dose ranges from T\ of a grain to £ of a grain. Eegota—Ergot. T$ Ext. ergotse, 3j; aqua), |j. M. Sig.: Twenty min- ims contain two (2) grains. Quinina—Quinine. 1$ Quininee disulphat., gr. 1 (50) ; acid, sulphuric, dil., Til c (100); aquas font. |j; acid, carbolic, liq., TTl v (5). Solve. Place the quinine and water in a porcelain dish over a spirit-lamp; heat to the boiling-point, and add the sulphuric acid, stirring with a wooden spatula. Filter at once into a bottle, and add the carbolic acid. This gives six grains to the drachm. The above is the formula of Dr. Lente as given by himself. All solutions containing sulphuric acid are very irritating. Hence, those which can be pre- pared without acid are much to be preferred. The hydrobromate of quinia is soluble in a degree sufficient for hypodermatic use: thus, 5, Quininas hydrobromat., gr. xlviii; aquae destil., 3 iv. M. Dissolve, and by heat if necessary. Sig.: Twenty (20) minims contain 4 grains. Quinina bimuriatica carbamidata, a combination of quinine and urea, is freely soluble—in equal parts of water, in fact—and therefore a most useful preparation for hypodermatic use. Acidum Carbolicum— Carbolic Acid. ]$ Acid, carbolic, purif., gr. x; aquas, § j. M. Sig.: Eight minims contain | of a grain. The quantity administered will range from one sixth of a grain to two or three grains. Hydrargyrum—Mercury. The solutions of mercury now chiefly used are those of the corrosive chloride and the albuminate. Formulas for both are sub- joined : 5 Hydrarg. chlor. cor., gr. j; aquas, f j. M. Sig.: Ten (10) minims con- tain J3- of a grain. Various albuminous solutions of mercury have been proposed: the chlorides of mercury, ammonium, and sodium, mixed with albumen. Arsenicum—Arsenic. The preparations of arsenic used hypodermatically are Fowler's and Pearson's solutions; the former in doses from two (2) to ten (10) drops, and the latter in twice the quantity. Aquapuncture.—By aquapuncture is meant the injection of pure water beneath the skin. A special instrument has been invented to effect this; but ordinarily a hypodermatic syringe will suffice for this purpose. From a half- drachm to a drachm is thrown under the skin over the organ or part on which it is intended to act. Irritant Injections.—Injections intended to excite local inflammation are also employed in various morbid states. The materials so used, and the condi- tions requiring them, will be set forth hereafter. IV. BY THE VEINS. The injection into the veins of medicinal agents is too dangerous a procedure to be lightly undertaken, and is admissible only in emergen- cies^ Formerly, before the introduction of the hypodermatic method, the injection of medicines directly into the blood was suggested and
