 may be used in the usual form and manner, the ointment 

 being applied pretty extensively, and in such a manner 

 as to invest the whole of the joint, not so much, however, 

 being applied on the flexion side of the joint, as on 

 the other parts, as a considerable irritation — and one

 be looked upon with suspicion, as, when bearing such marks, 

 it is not at ail unreasonable to suppose that he occasionally 

 stumbles and falls, to the great discomfort of his rider or 

 driver. 



Speedy-cut. — This condition consists of a contused wound,
