positions of bones when dislocated compared with the 

 normal ones. 



In studying Regional Anatomy the parts must be 

 regarded as being wounded, either by the surgeon's 

 knife or by some weapon, or displaced by accident. In 

 the various stages of a dissection made in the prosecution 

 of Descriptive Anatomy, it is often the end and aim of 

 the dissector to make a clean or " pretty " preparation, 

 in following out the different vessels, nerves, &c., and 

 for this purpose it is quite right that all pains be taken, 

 but the student must remember that the more he cleans, 

 the more he destroys the actual relation of the parts as 

 they would be met with in an operation ; and, moreover, 

 he must remember that the very fasciae he so studiously 

 removes, are of the greatest importance in Surgical 

 Anatomy, and their removal destroys surgical conti- 

 nuity. 



The want of material in our schools is the great 

 drawback to the study of Topographical Anatomy, as 

 bodies cannot be spared for such sections and special 

 examinations as a consideration of the various operative 

 proceedings of surgery suggests.
