HUXLEY AND YOUMANS. 

 The Elements of Physiology and 



Hygiene. With Numerous Illustrations. 



BY THOMAS H. HUXLEY, LL. D., F. R. S., and 

 WILLIAM JAY YOUMANS, M. D. 



New and Revised Edition. 1 vol., 12mo. 420 pp. $1.75. 



A text-book for educational institutions, and a valuable elementary 

 work for students of medicine. The greater portion is from the pen of 

 Professor Huxley, adapted by Dr. Youmans to the circumstances and 

 requirements of American education. The eminent claim of Professor 

 Huxley's " Elementary Physiology " is, that, while up to the times, it 

 is trustworthy in its presentation of the subject ; while rejecting dis- 

 credited doctrines and doubtful speculations, it embodies the latest 

 results that are established, and represents the present actual state of 

 physiological knowledge. 



" A valuable contribution to anatomical and physiological science." Religious Telescope. 



"A clear and well-arranged work, embracing the latest discoveries and accepted theories."

HUXLEY.

Author of "Man's Place in Nature," "On the Origin of Species," "Lay Sermons and 



Addresses," etc.

The former works of Prof. Huxley leave no room for doubt as to the impor- 

 tance and value of his new volume. It is one which will be very acceptable to 

 all who are interested in the subject of which it treats. 



" This long-expected work will be cordially welcomed by all students and teachers of Com- 

 parative Anatomy as a compendious, reliable, and, notwithstanding its small dimensions, most 

 comprehensive guide on the subject of which it treats. To praise or to criticise the work of so 

 accomplished a master of his favorite science would be equally out of place. It is enough to 

 say that it realizes, in a remarkable degree, the anticipations which have been formed of it ; 

 and that it presents an extraordinary combination of wide, general views, with the clear, accu- 

 rate, and succinct statement of a prodigious number of individual facts." Nature.
