By James J. Walsh, M. D., Ph. D., LL.D., Dean and Professor of the History of Medicine at Fordham University School of Medicine, N. Y. Second Edition, 1909. 362 pp. Price, $2.00 net. _The London Lancet_ said: "The list is well chosen, and we have to express gratitude for so convenient and agreeable a collection of biographies, for which we might otherwise have to search through many scattered books. The sketches are pleasantly written, interesting, and well adapted to convey the thoughtful members of our profession just the amount of historical knowledge that they would wish to obtain. We hope that the book will find many readers." _The New York Times_: "The book is intended primarily for students of medicine, but laymen will find it not a little interesting." _Il Morgagni_ (Italy): "Professor Walsh narrates important lives in modern medicine with an easy style that makes his book delightful reading. It certainly will give the young physician an excellent idea of who made our modern medicine." _The Lamp_: "This exceptionally interesting book is from the practiced hand of Dr. James J. Walsh. It is a suggestive thought that each of the great specialists portrayed were god-fearing men, men of faith, far removed from the shallow materialism that frequently flaunts itself as inherently worthy of extra consideration for its own sake." _The Church Standard_ (_Protestant Episcopal_): "There is perhaps no profession in which the lives of its leaders would make more fascinating reading than that of medicine, and Dr. Walsh by his clever style and sympathetic treatment by no means mars the interest which we might thus expect."
