For those who are interested in any phase of knowledge pertaining to the spleen, this work should be of great value. Its review of the literature is particularly international and well correlated and is systematized under headings especially adapted for ready reference without one's necessarily having to read the whole volume. The book is well indexed and therefore should be also of value for ready reference, especially for those wishing immediate orientation for further detail study. It deals with both experimental and clinical facts and presents no particular theory as a dominant theme. The author has apparently submerged his own conceptions for the sake of breadth of scope, despite the fact that he has been a voluminous contributor to the subject. Such an extensive review of literature would naturally not lend itself to illustration.
