Origin of Man

We noted here and there a few weak points-for example, the laboratory diagnosis of smallpox is given little space and not emphasized sufficiently. Again, in a book whose illustrations are so excellent it is surprising to find that some of the x-ray reproductions are reaily bad and some might have been omitted with advantage. But these do little to detract from a volume of very high general excellence. Since the book is American it includes accounts of diseases of slight importance in Britain, but we can repeat the prophecy we made on the first edition"This book will be greatly appreciated in this country by all who have to do with the management of infectious diseases."
