LESSONS IN HYGIENIC PHYSIOLOGY 



By W. M. COLEMAN. x+27i pages. 198 illustrations (16 colored, 

 13 full-page plates). 60 cents net. 



In Lessons in Hygienic Physiology the study of physiology 

 is simplified without weakening the presentation of its three 

 essential principles the biological principle of environment, 

 the chemical principle of oxidation, and the physical principle 

 of energy. The subject is approached throughout from the 

 standpoint of health, because "this is the most useful as well as 

 the most interesting point of view. The question of temper- 

 ance is treated fully, but at the same time in a conservative 

 manner. The book is fully illustrated, one hundred and ninety- 

 eight figures being furnished, sixteen of which are colored. 

 The Lessons is suited to the needs of teachers who may find 

 the Elements somewhat too advanced for their classes. 



ELEMENTS OF PHYSIOLOGY 



By W. M. COI.EMAN. xii + 364 pages. A very full course in Physiology 

 and Hygiene. Profusely illustrated in black and white and in 

 colors. 90 cents net. 



This book has an exceptionally large number of illustrations 

 two hundred and forty-eight, of which eight are full-page 

 colored plates. The need for *a compound microscope is 

 largely obviated by sixty microscopic views of cells and tissues. 

 The Elements is provided with a Colored Manikin arranged to 

 show every important organ in its natural position with refer- 

 ence to the organs before it, behind it, and around it. Since 

 every pupil has the manikin while studying each lesson, it is 

 really more serviceable than the manikins usually found in 

 schools. This book contains twenty-five Thought Lessons 

 of about ten questions each, logically developing different 

 lines of thought ; also three hundred questions in Applied 

 Physiology.
