Excerpt from A d104-Book of Physiological Chemistry, for Students of Medicine In the following pages I have attempted to present a brief account of the important principles of physiological chemistry in a form suitable for the use of medical students who may be assumed to have completed courses in the elements of general inorganic and organic chemistry. From the very necessities of the case a work of this character, dealing with many topics in an elementary way, must be largely a compilation; in the selection of material, besides consulting the standard hand books, I have made free use of the recent monographs by Cohnheim. Effront and Oppenheimer, as well as of numerous articles in the Zeitschrift fur physiologische Chemie, the Beitrage zur chemischen Physiologie und Pathologie and other journals. As the book is intended for beginners I have not thought it necessary to make any special quotations of literature references. In addition to the usual topics of discussion in elementary works on physiological chemistry I have given an outline of the chemical phases of the recent theories of immunity, and a short explanation of the important applications of the methods of cryoscopy and electrical conductivity, and other physical processes, in the field of chemistry related to medicine. Work in these latter lines must soon become a part of the laboratory training of medical students. A considerable number of illustrative experiments are given in the text, but distinguished by being printed in smaller type. These experiments are sufficiently numerous and comprehensive to serve the purpose of a laboratory course parallel with the general course. In the work of proofreading I have received very material assistance from my colleague, Dr. W. H. Buhlig, to whom my sincere thanks are due.
