X PREFACE TO THE FIRST EDITION. 



other hand, the limits of time ordinarily available for labora- 

 tory work have led to the almost entire omission of systems, 

 such as the muscular, which are of subordinate educational 

 value. 



Although this is essentially and professedly a laboratory 

 text-book, yet morphological explanations have been freely 

 admitted ; and this from a conviction that a student best 

 grasps the meaning of anatomical facts if the explanation is 

 given him while the facts are actually before his eyes. 



Illustrations have been introduced somewhat sparingly, 

 for it is of the utmost importance that they should not be 

 allowed to replace the drawings which a student must make 

 from his own dissections. The majority of the figures here 

 given are new, and have been drawn expressly for the book 

 by Mr. Hurst or myself. The drawings on the wood were 

 made by Mr. P. Hundley, and the blocks engraved by Mr. G. 

 Pearson : both these gentlemen have taken great pains to 

 render the figures at once faithful and artistic.
