part, which knowledge he must finally complete upon the 

 living animal. No dissection of the cadaver can ever teach 

 true surgical structure as the dead tissues can not be like 

 the living, but such dissection can and does give great aid 

 and should be pursued as far as it can lead and enough will 

 still remain to be learned on the living subject. It is to be 

 constantly remembered that anatomy deals with the struct- 

 ure of the dead body while surgical operations are performed 

 upon the living structures : they are not alike. 



The student should further take occasion to study in con- 

 nection with each operation the object or objects for which 

 it is performed in practice, its effect on the diseased or other 

 parts, the untoward results to be anticipated, etc. 



Suggestions occur from time to time in the text designed 

 to aid the student in these lines and help weave connecting 

 bonds between the operation, its objects and results. 



Surgical operations may in themselves be valueless or 

 worse and acquire value only when properly correlated to 

 disease and skillfully performed.
