Actions and Uses.—Its action is the same as that of calomel, but it is claimed to be superior because of its solubility in water, acting more rapidly and efficiently. Calomelol is claimed to be non-irritant and particularly non-toxic. The indications for its use are the same as for calomel. Dosage.—Internally the same as calomel. Externally it is used as a dusting powder, mixed with an equal quantity of starch or of a mixture of starch and zinc oxide, or in the form of calomelol ointment. It should be guarded from the light. Manufactured by the Heyden Chemical Works, New York. CALOMELOL OINTMENT. Actions and Uses.—It is a substitute for mercurial ointment, over which it has the advantage of cleanliness, and it is claimed to be distinctly superior as an inunction in syphilis, etc. Dosage.—6 grammes (90 grains) daily for inunction in syphilis. Manufactured by the Heyden Chemical Works, New York. CASCARA EVACUANT. A preparation said to contain a bitterless glucoside, obtained from the bark of _Rhamnus Purshiana_, with aromatics. Actions and Uses.—It is claimed that this preparation possesses the laxative properties of cascara sagrada without the bitterness which characterizes the ordinary extract. It is recommended for the treatment of chronic constipation, for which cascara sagrada is one of the best medicinal agents. Dosage.—As a laxative, 0·6 to 1 c.c. (10 to 15 minims) three times a day; as a purgative, 1·3 to 2 c.c. (20 to 30 minims) morning and evening. Four cubic centimeters (1 fluidrachm) may be given in obstinate cases.

Each globule is said to contain 0·2 gramme (3 grains) of the bitter glucosides of _Rhamnus Purshiana_ suspended in a bland fixed oil, to which aromatics have been added.

Dosage.—One or two globules to be taken before retiring. Prepared by Parke, Davis & Co., Detroit, Mich. CHINAPHENIN.
