Dr. Jas. W. Holland, who has attained such eminence in other fields. This is the third edition of his book, which we have previously noticed, and it has been thoroughly revised and brought up to date.

The introduction of the book takes up Matter, Force, Heat, Electricity and Light; The Chemical Elements; Organic and Physiologic Chemistry, and the Energy of Foods.

Taking into account the unpreparedness of most students of medicine in elementary chemistry, Dr. Holland has written this book so as to take them through the course from the beginning, including physiologic chemistry, which is so important from a medical standpoint. This book is practical, thorough and complete.

As a text book or reference work, it is one of the best.
