Dr. Dennie's object in this work has been to write a practical book as compact as possible but covering the entire subject of syphilis. It is a difficult undertaking, but it may be said at once that the book is excellent. His style is clear and direct, and his teaching is sound. He uses some striking phrases, as when speaking of the lack of tissue reaction in the early days of the invasion of the spirochete he says: "A few leukocytes make their appearance, but they seem to be on friendly terms with the invading parasite."
Some of his usage does not appeal to the reviewer. Instead of the term hereditary syphilis, he uses throughout the book, not as a compound word but as two words, that horrible phrase heredo syphilis. He chooses also to use Treponema pallidum instead of Spirochaeta pallida. The selection of words depends on good usage,
