PREFACE TO THE SECOND EDITION. 



CIRCUMSTANCES independent of my will Lave prevented me from publishing 

 the Second Edition of my ' Treatise on Anatomy ' earlier. Those to whom 

 the work is addressed will have lost nothing by the delay, as it has allowed 

 me to procure the co-operation of one of my most distinguished and best- 

 esteemed pupils. 



The researches in pathological physiology and experimental medicine, 

 to which I have consecrated my efforts and resources for some years, would 

 have left mo no leisure to do more than give a simple reprint of my first 

 edition ; consequently, I must have allowed important omissions to remain, 

 and have renounced the idea of re-casting it according to a new plan I had 

 conceived, even before that edition was terminated. 



Thanks to the assistance of M. Arloing, who had long before been 

 initiated into my projects, and the details as to their execution which had 

 been present to my mind, this re-casting has been accomplished, and the 

 ' Treatise on the Comparative Anatomy of the Domesticated Animals ' has 

 thus become an almost entirely new work. 



I need not attempt to indicate the importance of the modifications and 

 considerable additions that this remodelling has entailed ; nor the ame- 

 liorations which the publishers have introduced in the execution of the 

 material portion of the work. It is sufficient to open Ihe book to be 

 convinced of these advantages.
