Chorea, shivering, or St. Vitus' dance. 

 — In the horse this appears to be an in- 

 curable disease, and constitutes unsound-

 affection can be worked with a breast-band. 

 Another cause is that of fraying of the 

 lining of the collar. 



A good-fitting collar should have equal 

 pressure all round the shoulders, without
