Examinations of Water, Milk, Blood, Urine, Sputum, Pus, Food Products, Beverages, Drugs, Minerals, Coloring Matters, etc., for diagnostic, prophylactic, or other scientific purposes.

All analyses at these Laboratories are so conducted as to assure the best service attainable on the basis of the latest scientific developments. The laboratories are amply supplied with a perfect quality of reagent materials, and with the most efficient constructions of modern apparatus and instruments. The probable cost for some of the most frequently needed researches is approximately indicated below:

The cost for other analyses—more variable in scope—can only be given upon closer knowledge of the requirements of individual cases.

All pharmacists in every part of the United States will receive and transmit orders for the Merck Analytic Laboratories.

Physicians are earnestly requested to communicate to Merck & Co., University Place, New York, any suggestions that may tend to improve this book for its Second Edition, which will soon be in course of preparation.

Whatever the Publishers can do to make Merck's Manual of still greater service to the Medical Profession will be gladly undertaken and promptly performed for all subsequent editions.

Therefore, any Physician who will propose improvements in the subject-matter (especially as regards the Newer Materia Medica), or in the arrangement, style, and form of this work, for future editions, will thus be rendering valuable service, not only to its Publishers, but to the entire Profession as well!

CHEMICALS AND DRUGS USUAL IN MODERN MEDICAL PRACTICE

Compiled from the Most Recent Authoritative Sources and Published by

MERCK & CO., NEW YORK

Copyright by Merck & Co., New York, 1899

MERCK'S MANUAL is designed to meet a need which every general practitioner has often experienced. Memory is treacherous. It is particularly so with those who have much to do and more to think of. When the best remedy is wanted, to meet indications in cases that are a little out of the usual run, it is difficult, and sometimes impossible, to recall the whole array of available remedies so as to pick out the best. Strange to say, too, it is the most thoroughly informed man that is likely to suffer to the greatest extent in this way; because of the very fact that his mind is overburdened. But a mere reminder is all he needs, to make him at once master of the situation and enable him to prescribe exactly what his judgment tells him is needed for the occasion.

In MERCK'S MANUAL the physician will find a complete Ready-Reference Book covering the entire eligible Materia Medica. A glance over it just before or just after seeing a patient will refresh his memory in a way that will facilitate his coming to a decision. In this book, small as it is, he will find the essential data found in the ponderous Dispensatories, together with the facts of newest record, which can appear only in future editions of those works.

Part I affords at a glance a descriptive survey, in one alphabetic series, of the entire Materia Medica to-day in general use by the American profession. Part II contains a summary of Therapeutic Indications for the employment of remedies, arranged according to the Pathologic Conditions to be combated. Part III presents a Classification of Medicaments in accordance with their Physiologic 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 possessor.

CONTENTS.

Pages 9 to 82.

Part First.—THE MATERIA MEDICA, as in actual use to-day by American Physicians. (Alphabetically arranged.)

This part embraces all those Simple Medicinal Substances (that is, drugs and chemicals) which are in current and well-established use in the medical practice of this country; or which, if too recently introduced to be as yet in general use, are vouched for by eminent authorities in medical science;—also, the medicinally employed Pharmaceutic Preparations recognized by the United States Pharmacopœia.

(Added thereto, for the convenience of those practitioners who prescribe them, are Medicamentous Mixtures advertised only to the Profession, but whose composition or mode of manufacture has not been made known with sufficient completeness or exactness to satisfy all members of the Profession. In the selection the publishers have been guided solely by the recognition accorded the various preparations by the Profession, according to the best information obtained.)

There has also been included, under the title of "Foods and Dietetic Preparations," a list of such preparations as are frequently prescribed for infants' diet, or for the sick or convalescent.

Omitted from the Materia Medica chapter are: Medicaments that have become obsolete, or that are too rarely used to be of general interest; and such new remedies as are not yet safely accredited on reliable authority; also those galenic preparations (syrups, extracts, pills, essences, elixirs, wines, emulsions, etc.) which are not standardized according to the U.S. Pharmacopœia; 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).

Pages 83 to 184.

Part Second.—THERAPEUTIC INDICATIONS for the use of the Materia Medica and other agents. (Arranged alphabetically under the titles of the various Pathologic Conditions.)

This part summarizes in brief form, the principal means of treatment for each form of disease, as reported to be in good use with practitioners at the present time. The statements hereon are drawn from the standard works of the leading modern writers on Therapeutics, and supplemented—in the case of definite chemicals of more recent introduction—by the reports of reputable clinical investigators.

Pages 185 to 192.

Part Third.—CLASSIFICATION OF MEDICAMENTS according to their Physiologic Actions. (Arranged alphabetically under the titles of the Actions.)

This part recapitulates, for ready survey, such statements as are already given in "Part I," as to the modes of action of the various medicaments.
