This book, written at the request of the author's numerous colleagues, aims to present accurate, reliable and rapid methods for the scientific preparation of pharmaceutic products. It does not pretend to be comprehensive but includes all that is necessary for the daily problems of the practicing pharmacist, especially methods for the preparation and conservation of medicaments. Because it is designed for the practical pharmacist, the author does not include biologic testing; but he tells where such methods of testing may be found. The book gives the impression of having completely and satisfactorily fulfilled the aims of the author. He does not discuss therapeutics but writes purely for the pharmacist and those interested in pharmacy. A good index is included. If one may judge the condition of Spanish medicine from this treatise on pharmacy, it is modern and progressive.
