PREFACE. 



THE present book is a brief summary of the salient features 

 of Human Physiology. It is not intended to compete with nor 

 to take the place of the more elaborate text-books. The idea 

 has been to present the subject in such a manner as to fix in 

 the memory facts already learned in less limited treatises. 



There is no claim of originality for this book. It is practi- 

 cally and of necessity an abstract of standard works, and princi- 

 pally of those of Dalton, Foster, and Kirke. The arrangement 

 has, in a general way, been made to conform with that of the 

 last-named authority. The cuts are many of them from Dalton's 

 Physiology. Doubtful questions have often been referred to 

 Foster, whose Text-book of Physiology is the reference-book of 

 a large proportion of the schools. Some of the histological 

 descriptions are derived from Prudden's Practical Normal His- 

 tology.
