One of the most valuable features of this textbook is the series of drawings in black and white by Freytag. These illustrations are admirably done. The colored plates also, which are from Jacobi's historic atlas, are masterpieces of their kind. The text, for so large a volume, is rather sketchy and incomplete. The section on syphilis, pages 382 to 566, probably is best. The suggestions regarding treatment are practical. Apparently the author has great confidence in mercury as a spirocheticide. Malarial therapy in syphilis is discussed, but heat treatment does not receive the attention that its value merits. About 10 per cent (seventy pages) of the first volume is devoted to the history, symptomatology and treatment of gonorrhea. The index is comprehensive.
