This book represents essentially a compilation of the various therapeutic agents obtainable in the Long Island College Hospital. It has been prepared with the following objectives in view: "1. To acquaint the members of the Hospital Staff with the preparations carried in the Hospital Pharmacy for use in the In-and Out-Patient Departments; 2. To outline the dose, route of administration, size and nature of package of each material presented; 3. To indicate those conditions for which the preparations are employed." This purpose the authors have admirably fulfilled. This handbook should be of use to the house staff of the Long Island College Hospital as well as to the staffs of similar institutions, although in other institutions some of the therapeutic agents mentioned may not be obtainable.
