286 DISEASES OF CATTLE.

 Veterinary surgeons use a trocar for this purposa, and 

 every farmer should have one also. If the case be not a 

 severe one, it may be entrusted to time, nature and medi- 

 cine. Give half a pound of table mustard, and an ounce 

 of the chloride of lime, mixed in as little cold water as M^ill

 beast often cures the affection, by inducing reflex action of

 gentian, half an ounce; fenugreek, half an ounce; mix, 

 and give in one dose, and continue it for a few days.

 however, is not always the case. The great symptom 

 chiefly to be relied upon, is the constant turning of the 

 animal in the form of a circle. This, the animal will 

 always persist in doing, and stop only when brought in
