PREFACE TO SECOND EDITION 



IT was the aim of the authors in writing this work for 

 its original edition to gather within brief compass those 

 facts of Physiology with which medical students should be 

 familiar in order that they might successfully pursue the 

 more advanced courses of the medical curriculum. It was 

 not the intention to produce a work of originality nor one 

 which should take the place of more elaborate text-books 

 in the instruction of students, but one offering a means 

 of quickly reviewing the essential features of the subject. 

 The demand which exhausted successive printings of the 

 first edition indicates that the work answered its purpose 

 as a brief exposition of Physiology suited to the needs of 

 students and practitioners, and it is hoped that this new 

 and thoroughly revised issue may meet with equal favor.
