be felt. A fore leg should, however, be held up on the same side as the 
operator stands. Should the horse strug-

cautious, as the too near vicinity to the in- 
flamed part provokes resistance, which, in 
its utter heedlessness, is closely allied to 
madness. 
Several reasons will suggest the point at

place, pressure cannot benefit a delicately-formed and a diseased organ. 
In the second place, the agony of the animal may endanger the safety of 
the operator. In the last place, anything approaching to downright 
resistance brings the muscles that pass under the kidneys into ener- 
getic action, which circumstance is by no means favorable to ultimate 
recovery
