Stiles' Human Physiology 



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

 written by a teacher 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.

 vard University. Cloth, $1.50 net. 



Fred's Soil Bacteriology 



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

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

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

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

Herrick's Neurology 



Professor Herrick's new work is sufficiently elementary to be used by students of elemen- 

 tary psychology in colleges and normal schools, by students of general zoology and com- 

 parative anatomy, and by medical students as a key to the interpretation of the larger 

 works in neurology.

Winslow's Prevention of Disease 



This book gives briefly the means to avoid disease. The chapters on diet, exercise, tea, 

 coffee, and alcohol are of special interest, as is that on the prevention of cancer. There are 

 chapters on the prevention of malaria, colds, constipation, obesity, nervous disorders, 

 tuberculosis, etc. The work is a record of 25 years' active practice.

 entire range of health questions — care of mouth and teeth, catching cold, adenoids and 

 tonsils, e3-e and ear, ventilation, skin, hair and nails, nutrition, nervous ailments,cough, etc.
