Whatever may be said of this book, it is certainly different. It takes up the first year of life, and this is divided into three sections, from birth to 1 month, from 1 month to 6 months and from 6 months to 1 year. Each of the diseases is treated briefly in each section. The author has recorded his experience in seeing outpatients at the Great Ormond Street Hospital, London, for a period of twenty-five years. He states that he has analyzed 8,823 consecutive cases. Some of the book appears rather too short to be adequate. The author has coined a new word, "hyperphlebaemia," which he defines as "an excessive quantity of blood forced into the intracorporeal venous system during birth before it is ready to receive it." He evidently attaches great importance to this condition, since he discusses in connection with it no fewer than forty-six definite clinical entities.
