GEORGE HENRY FOX, A.M., M.D. Formerly Professor of Dermatology, College of Physicians and
Surgeons, Columbia University, New York.
The volume is written in a most pleasing and readable manner, and gives not only interesting details of medical study at home and abroad, descriptions of widely known,teachers, bits of travel, amusing stories, etc., but much that is of great historical value. It is an ideal book for the physician's waiting-room table, since anyone opening it at any page and reading at random is certain to become fascinated by it.
