This little volume commends itself to the reader as a practical and useful one. It approaches the subject rather from a clinical than a purely didactic standpoint and in many ways supplements the standard text-books, while in no way intended to supplant them. Thus Dr. Thomson devotes 13 pages to pyloric stenosis, and nearly 40 pages to mental defects, while infant-feeding is dismissed with about 30 pages. This tendency is further seen, and advantageously, in the many excellent and original illustrations, notably of pyloric stenosis, meningitis, chloroma, and of that interesting and, in this country, rare lesion, rheumatic nodules. The book distinctly reflects the ideas, methods and interests of one of the great English teachers of clinical pediatrics, and should find a welcome among us.
