The object of this book is to introduce the student to the study of Pharmacology and Therapeutics, with the purpose constantly in mind of preparing him tor the prac-tice of medicine, i. e., to care for the sick.

The Section on Experimental Pharmacology is, perhaps, too brief, but is intended only as an introduction to the laboratory course which is now offered by most schools. The following section, on known Actions of the Important Drugs, is arranged alphabetically to allow the instructor free choice of the drug he will first demonstrate, and the student a ready reference to the physiologic action of that drug.

The section on Pharmacy and the Pharmacopoeia is intended to offer captions for as many pharmacy lectures or demonstrations as the curriculum of a school provides for, and to explain the important preparations of the United States Pharmacopoeia. The doses of the pharma-copoeial preparations arc made smooth for both systems, and preparations are grouped according to the size of the doses, this, perhaps, being the best means of helping students to remember them. The latter part of this section is for reference, especially for doses.

The next section, on Poisoning and its Treatment, is for reference or study, as desired.

The section on Weights and Measures, Latin Abbreviations, Prescription Writing and Dosage, is intended to introduce the Subject of writing prescriptions, which can, of course, only be perfected by continued practice throughout the course in Pharmacology and Therapeutics.

The next section briefly describes the various methods of locally treating different parts of the body. These methods are, perhaps, better placed in a book of this introductory type, than in a Large book devoted to the study of the physiologic action of drugs and their therapeutic application.

It is a pleasant duty to acknowledge the invaluable cooperative work done in preparing this book by my associate, Dr. William Hill Bean, Assistant in the Medical Clinic. I also wish to thank, for their valuable suggestions, Lafayette B. Mendel, Professor of Physiological Chemistry; Yandel Henderson, Assistant Professor of Physiology, and Clarence G. Spalding, Demonstrator of Pharmacy.
