In this monograph the history, the diagnosis and the course of hemophilia and the condition of the blood are discussed briefly but completely, and there are excellent illustrative plates. The major part of the book consists of the histories of ninety-eight patients, with seventy-five genealogical charts. These charts have been painstakingly compiled, and the family histories have been followed back an amazing distance. One, for example, carries the family back to 1638. So far as possible, controversial matter has been avoided, and the discussion is limited to verified data.
The book represents the fruit of nine years' study by the author, and never before has such a mass of statistics been obtained on hemophilia. Dr. Birch can well be proud of this work. Incidentally, the printing, the illustrations and the binding of the book have been beautifully done.
