The author has undertaken a systematic study of the development of the human central nervous system from both the macroscopic and the microscopic standpoint. He has prepared sections of the fetal brain by most of the principal staining methods and reproduces unretouched photographs of these sections. The earliest stage is represented by one 14 mm. embryo, and the greater part of the book deals with specimens the gestation age of which was more than four months. This much can be said of Dr. Barbé's investigation: He has been honest in disclosing the imperfection of his material. Most of the fetuses, one may judge from the illustrations, either were poorly preserved or were abnormal. Many of the photomicrographs of sections show so little normal embryonic development as to be of no value whatever. Although there exist in other languages a number of excellent works on development of the nervous system, the
