THE book before us, which is correctly described by the author as a handbook, is intended “to act as a guide to clinical study” to young practitioners of medicine, and those who have not previously paid much attention to the subject. After introductory chapters treating of growth, clinical examination and food, the author proceeds to consider the individual diseases of children, and to indicate how the pathological processes, and their accompanying clinical phenomena, are different in children and adults. It would, of course, be impossible in a short notice like the present to give an account of the varied and practical information contained in Dr. Williams's book. Under the heading of diphtheria, the results of the antitoxin treatment, as Culled from the statistics of the Metropolitan Asylums Board and the American Pediatric o Society, are given, the author rightly observing that the statistical figures are actually less favourable than the reality. The interesting subject of the effect of the antitoxin treatment upon the complications of diphtheria, so often of such importance in children, is also discussed. Cretinism and its treatment by administration of the thyroid gland is considered. Hepatic disease in children, often a subject of considerable difficulty to the practitioner, is well treated. A list of prescriptions, a few invalid cooking receipts, and a good index conclude the volume. The book will unquestionably be of use to the general practitioner and the student, and, while not capable of replacing the larger text-books on the diseases of children, will form a most valuable supplement to the various treatises on general medicine.
