PREFACE 



In approaching the revision of " Huxley's Physi- 

 ology," my feelings haA^e been similar to those of an 

 architect to whom is entrusted the restoration of a 

 historic building designed by a master hand. 



Written by Huxley, the book was revised, and in 

 fact almost rewritten, by Foster. The former was 

 as great a writer as any scientist of his time, the 

 latter may almost be said to have created English 

 Physiology. 



To " restore " the work of these men from the 

 dilapidations made by two decades of scientific 

 progress is the task now entrusted to me. The 

 sense of responsibility with which I approach it is, 

 if possible, heightened by the affection which I have 

 for the memory of Foster, who was my master. 



I have faithfully left untouched any portion of 

 the fabric in which there was not an actual flaw;
