This little book might be said to be composed of a series of definitions. It is divided into two parts, the first in which the abnormal phenomena are defined, the second in which the complexes of abnormal phenomenna, that is the various symptom groups, are defined. Such a book naturally has all the faults of an attempt to compress a living subject into the confines of short, terse definitions. The result naturally tends to be static and purely descriptive rather than interpretative. It is exceedingly stimulating, however, to note that it is the work of a psychologist and to realize that the university psychologist is beginning to take an interest in mental pathology. The presentation is well done from the point of view of the author, though the scheme is not one that commends itself to the reviewer.
