CONTAINING

Names and Chief Synonyms, Physical Form and Appearance, Solubilities, Percentage Strengths and Physiological Effects, Therapeutic Uses, Modes of Administration and Application, Regular and Maximum Dosage, Incompatibles, Antidotes, Precautionary Requirements, etc., etc.,—of the CHEMICALS AND DRUGS USUAL IN MODERN MEDICAL PRACTICE Compiled from the Most Recent Authoritative Sources and Published by MERCK & CO., NEW YORK Actions. The publishers may be allowed to state that they have labored long and earnestly, so to shape this little volume that it shall prove a firm and faithful help to the practitioner in his daily round of duty. They now send it forth in the confident hope that, the more it is put to the test of actual use, the more it will grow in the esteem of its po e or.   interest; and such new remedies as are not yet safely accredited on reliable authority; also those galenic preparations (syrups, extracts, pills, e ences, elixirs, wines, emulsions, etc.) which are not standardized according to the U.S. Pharma copœia; likewise all articles that are put up and advertised for self-medication by the lay public. Separate Titles in the alphabetic series are accorded, as a rule, to the botanical drugs and other pharmaceutical mother-substances, to proximate principles (alkaloids, glucosides, organic acids, etc.), and to chemical compounds (salts, "synthetics," etc.); while the official galenic preparations, solutions and dilutions, derived from them, are mostly mentioned under the titles of their respective mother-substances. (Thus, for instance, "Dover's Powder" will be found under "Opium," while "Morphine" is described under its own title.) ( Smaller type has been employed—in order to economize space—for botanic drugs, gums, and some others of the older drugs and preparations which are so long and well known that but little reference will need be made to them.) (Those substances of the Materia Medica which can be had of the Merck brand are—for the convenience of prescribers—so designated).
