Stiles' Human Physiology 



This new physiology is particularly adapted for high schools and genera! colleges. It is 

 written by ateacher who has not lost the point of view of elementary students. Professor 

 Stiles has the faculty of making clear physiologic processes more or less difficult of com- 

 prehension. This he does by the use of homely similes and happy teaching devices.

Fred's Soil Bacteriology 



The exercises described in this book are arranged primarily for students of soil bacteri- 

 ology, soil chemistry and physics, and plant pathology. As far as possible the experi- 

 ments are planned to give quantitative results. It is truly a valuable laboratory manual 

 — worked out by a teacher and based on the student's needs.

 w-orks in neurology.
