NOTE 



THE third volume of Professor Luciani's Human Physiology, 

 which deals with the muscular and nervous systems, has been 

 translated from the fourth Italian edition, which has appeared 

 since the publication of the English translation of Vols. I. and II. 



This edition, -in which the third and fourth volumes have 

 been enlarged and corrected in places by Professor Luciani, was 

 brought out in 1913 on which occasion a commemorative medal 

 and an album containing the autographs of almost all the world's 

 most eminent physiologists were presented to the Author. 



The English translation of the preceding volumes was edited 

 by Dr. M. Camis, but as he was unable to act again in this 

 capacity the Editorship of the present volume has been under- 

 taken by Dr. Gordon Holmes. 



LONDON, 1914.
