 VERTEBRA. 



The College Museum contains many cases of recovered fractured 

 scapulae ; and this bone is liable to be broken through its neck 

 or body by muscular contraction, and through its spine by direct 

 violence, caused by blows or falls, 



Compound fracture of the spine will sometimes be found to 

 exist with the fragments completely detached ; in such a case, 

 they must be removed. 



Wlien the body or neck is the seat of the lesion, if there is not 

 much displacement, speedy reunion will take place, and the ani- 

 mal completely recover, provided the articulation be not involved. 



But little can be done in these cases beyond enjoining quietude, 

 placing the animals in slings, and watching for untoward com- 

 plications. 



When the humerus is broken, I am of opinion that perfect 

 soundness is impossible, although Professor Dick taught that 

 such might take place. The practitioner w^ell knows that many 

 powerful muscles are attached to this bone, the action of which 

 will render the retention of the broken bone in anything like its 

 proper position an impossibility. Fractures of the tubercles, of 

 course, Hke those of the trochanters of the femur, will be an 

 exception to this rule. 



When the humerus is broken, there is an immediate shortening 

 of the limb, from the inferior portion of the bone being drawn 

 upwards by the muscles attached to it ; great lameness ; and 

 there is very often a rupture of the humeral artery, or of one of its
