 day's work," it is believed will be found advantageous, 

 not only as mapping out the labor before the Dissector, 

 but in giving him an opportunity to prepare in the 

 study, and in advance, for the dissection of each suc- 

 ceeding day. Practical suggestions as to the best 

 method of demonstrating, precede the descriptions of 

 the various regions and parts of regions. Illustrations 

 have been omitted, for the reason that they add to the 

 expense of a book, often without enhancing its real 

 value, and from the belief that they are liable to great 

 abuse, by distracting attention from the descriptive text 

 to the numbered references, the simple verification of 

 the latter taking the place of the full information only 

 to be obtained from the former.
