PREFACE.

The book, which this preface completes, has occupied the writer's leisure hours during the past two years, and in a measure has grown out of some less pretentious volumes previously written by him. The continued favor shown by teachers and students, both in this country and in England, to his three manuals in the “ Quiz-Compend” series for students, and particularly to the volume on Materia Medica and Therapeutics, has encouraged their author to hope that a hand-book from him on the same subject, but embracing a wider scope, might meet with a corresponding degree of appreciation. The fact that quite a number of new manuals on Materia Medica have lately appeared, has not deterred him from entering the field, nor diminished his confidence in the approbation of his readers; but has rather seemed a proof that most of the older text-books on this branch of medical knowledge are no longer satisfactory, even with the regular revisions which they undergo at stated periods. Hence he expects for this hand-book a position, among the recent manuals of its class, as high as its merits and demerits may entitle it to receive in the estimation of those for whose use it has been prepared.

The author's intention has been to produce a book, which 'would embrace in a single volume the Essentials of practical Materia Medica and Therapeutics, treating of each subject in as concise phraseology as possible consistent with the delineation of every important feature. He has also endeavored to formulate such minute and definite directions for the framing of Prescriptions, as might elucidate what to many is a very difficult problem. Furthermore, he has tried to present as much information, upon the subject of Pharmacy, as every physician should possess, in order to handle the implements of his profession with confidence, and to direct their use by others with pharmaceutical accuracy. The complete fulfilment of these aims would be realized if the book should take rank as a working companion to the advanced student and the junior practitioner; and be deemed by them a reliable guide through the forest of observations and experiments on drug actions and uses, which makes progress slow for the already over-burdened mind, when ploughing through the more exhaustive and exhausting text-books.

Although this book is essentially a compilation, as all books of its class must be, there will be found in its pages much original matter derived from the writer's own experience in professional life. The arrangement of the matter will be found to be in some respects unique. After full consideration of the many arrangements of the Materia Medica in vogue, a modified alphabetical plan was adopted, by which the advantages of the alphabetical order might be retained, while permitting the grouping together of agents which are closely related, physiologically and therapeutically, under the title of the principal member of the class-the chief, as it were, of that particular clan. Thus, under the title AMYL Nitris (Nitrite of Amyl), will be found mention also of the Nitrites of Ethyl, Sodium and Potassium, and their congener Nitro-Glycerin, all of which are closely allied to the first-named and to each other, in respect of their actions and uses. A very elaborate section on Drug Classification is placed at the end of the Materia Medica, in order to supplement such deficiencies in grouping as are inevitable in an alphabetical arrangement.

In detailing the characteristics of an important drug, its physical properties and chemical constituents are first briefly enumerated, then its preparations are described in the official language of the pharmacopæa, usually somewhat abbreviated ; any important unofficial preparations being also noted, and all the compounds into which it enters enumerated. Next the physjological action is taken up, its characteristic features being first described ; then the actions resulting from an ordinary medicinal dose, next those produced by small doses continued, and finally those from a toxic dose. These are followed by a brief account of its antagonists, antidotes and incompatibles, if any; and a

concise summary of its therapeutical applications closes the article ;—the whole presenting, it is hoped, a clearly definedword-picture of the drug under consideration. Every article and preparation comprised in the last edition of the U. S. Pharmacopoeia is fully noticed, while all the prominent unofficial agents receive such mention as their respective importance seems to demand.
