This new Atlas will be found even more valuable than the two preceding volumes on Special Pathologic Histology, to which, in a manner, it is a companion work. The text gives the generally accepted views in regard to the significance of pathologic processes, explained in clear and easily understood language. The lithographs in some cases required as many as twenty-six colors to reproduce the original painting. Dr. Hektoen has made many additions of great value. =W. T. Councilman, M. D.=, _Professor of Pathologic Anatomy, Harvard University_. “I have seen no plates which impress me as so truly representing histologic appearances as do these. The book is a valuable one.” Howell’s Physiology =A Text-Book of Physiology.= By WILLIAM H. HOWELL, PH.D., M. D., Professor of Physiology in the Johns Hopkins University, Baltimore, Md. Octavo of 915 pages, 275 illustrations. Cloth, $4.00 net. RECENTLY ISSUED--NEW (2d) EDITION 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.
