This little book is offered to the medical public as containing an account of the more common forms of cardiac affections as they occur in young persons. The author has omitted a consideration of the acute cardiac disorders which are for the most part complications of the general febrile states, such as rheumatic fever, and are therefore only incidentally touched upon. The book is largely made up of case records, with critical remarks appended, and it will be found an instructive work for reading by the general practitioner. Special attention is given to certain questions, such as education, sports, etc., in children, which are practical points whose inclusion will be appreciated. We agree with Sir Samuel Wilks in the introduction when he says the author has produced a book of great interest and value.
