The subject -- syphilis -- a direct informative book for the layman, treating a problem that deserves social as well as medical attention. Leaves manyunanswered questions but a fairly comprehensive study of the disease. History -- diagnosis -- various manifestations -- treatment -- cure. Chapters on preventive measures limited by the type. Fallacies extant, difficulty of identification and diagnosis, even by Wassermann tests. An unpalatable book to place, but deserves the effort through importance of its content. Compare shortly with the Parran book to be published by Reynal & Hitchcock. (Not yet available). Call to the attention of health agencies.
