THE recent advances in our knowledge of personal 

 and public hygiene and of sanitation have made 

 indispensable for the use of progressive educators a 

 practical and authoritative text-book of what may be called 

 " the new physiology and hygiene." The present work has 

 been prepared in recognition of this need. Professor Hough 

 has been engaged in the study and teaching of physiology 

 and personal hygiene for over ten years. Professor Sedg- 

 wick has had a large share in the advancement of the study 

 of public health and sanitation in America. They have 

 made the keynote of this work the right conduct of the 

 physical life, and to this end everything else is subordi- 

 nated. Anatomy and histology are only briefly outlined, 

 while special chapters are devoted to practical matters of 

 hygiene and sanitation. 



The authors believe that the matter and method of this 

 new text-book will go far toward rescuing physiology and 

 hygiene from the neglected and too often despised place 

 which they now occupy in schools, and promoting them to 

 ine of practical usefulness and corresponding esteem. 



The book is intended for high and normal schools, and 

 IT short courses in colleges.
