xii INTRODICTION. 



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.
