Dr. Howell has had many years of experience as a teacher of physiology in several of the leading medical schools, and is therefore exceedingly well fitted to write a text-book on this subject. Main emphasis has been laid upon those facts and views which will be directly helpful in the practical branches of medicine. At the same time, however, sufficient consideration has been given to the experimental side of the science. The entire literature of physiology has been thoroughly digested by Dr. Howell, and the important views and conclusions introduced into his work. Illustrations have been most freely used. ~The Lancet, London~ "This is one of the best recent text-books on physiology, and we warmly commend it to the attention of students who desire to obtain by reading a general, all-round, yet concise survey of the scope, facts, theories, and speculations that make up its subject matter."

In revising the book for the new edition the authors have kept in view the needs of the laboratory worker, whether student, practitioner, or pathologist, for a practical manual of histologic and bacteriologic methods in the study of pathologic material. Many parts have been rewritten, many new methods have been added, and the number of illustrations has been considerably increased. ~Boston Medical and Surgical Journal~ "This manual, since its first appearance, has been recognized as the standard guide in pathological technique, and has become well-nigh indispensable to the laboratory worker." * * * * * Eyre's Bacteriologic Technic ~Bacteriologic Technic.~ A Laboratory Guide for the Medical, Dental, and Technical Student.
