This monograph contains a considerable amount of valid material on a period of infancy which has attracted little interest among neurologists or psychologists. In general, the method is that of the psychologic laboratories of some years ago. The observation of various types of sensation with the time of occurrence of each and other similar observations are faithfully recorded.
In the opinion of the reviewer, this work, though interesting and of definite value, is by no means as useful as that of Arnold Gesell. Curiously enough, in a voluminous bibliography, Dr. Gesell's important contributions to the subject are not cited. On the other hand, Dr. Peiper calls deserved attention to the fundamental psychologic work of Magnus and illustrates its importance by admirable photographs.
