PREFACE 



THIS is in no sense a Text Book. It is rather 

 an attempt to state the leading principles and 

 facts of physiology, and more especially of 

 human physiology, in such a way as will be 

 understood by an intelligent reader who has 

 had no special scientific training. If the 

 perusal of this little book leads the reader 

 to wish to know more of this fascinating 

 science, which, in a sense, is the meeting-point 

 of many sciences, he is referred to the Bib- 

 liography, and the aim of the writer will be 

 accomplished.
