HERTER, M.D., Professor of Pharmacology and Therapeutics in Columbia University; Consulting Physician to the City Hospital, New York The Common Bacterial Infections of the Digestive Tract _And the Intoxications arising from Them_ _Cloth, 8vo, 360 pages, $1.50_ _by mail, $1.63_ “The methods of investigating the digestive tract outlined in this volume will prove valuable to the practitioner who would determine the presence of abnormal bacterial processes before the onset of the clinical signs of incurable or highly refractory states of intoxication--and this is the all-sufficient _raison d’être_ for the book. Considerable stress has been laid by the author on methods developed in his laboratory, in the belief that their painstaking application will furnish practitioners with reliable indications as to the progress of many cases of infection of the digestive tract.”--_Merck’s Archives._ “A very scholarly volume, primarily intended for physicians and students, yet, because of its grave importance and because the subject it treats of is of vital interest to all intelligent readers, we are quite certain the book will be appreciated and read in a far wider circle than its title, which is rather ‘professional sounding,’ might warrant. We call the reader’s attention especially to the last chapter in the book, in which there is expounded much valuable material of common interest.”--_Times._ On Infantilism from Chronic Intestinal Infection _Cloth, 12mo, 240 pages, 90 cents_ _by mail, $1.02_ “Dr. Herter’s book is bound to have the effect of broadening our conception of the subject of infectious diseases of the intestine, and deserves a wide reading.”--_George C. Whipple._ * * * * * Introduction to General Science BY PERCY E. ROWELL, B.SC. _Cloth 12mo 302 pages $.75_ The increasing demand for a thorough, comprehensible, and practical textbook on the subject is met by Rowell’s “Introduction to General Science,” the distinctive features of which are: 1. The book gives a broad, adequate view of the general field of science. The elements of physics and chemistry receive particular emphasis, but biology, physiography, and several phases of applied science are duly considered.
