332 DISEASES OF CATTLE. 



symptom chiefly to be relied upon, is the constant turn- 

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

 animal will always persist in doing, and stop only when 

 brought in contact with a stone wall or fence, which pre- 

 vent further circular turning. Unfortunately, the poor 

 animal comes in contact with the wall with such force, 

 and so often repeated, that on that side of the head will 

 be seen swellino-s and enlarg-ements of the bones of the 

 jaw. In this way does the affected beast turn the circuit 

 from day to day until emaciated from weakness and 

 hunger. The end of some' cases is more shoi't than this 

 for not unfrequently they fall into holes, rivers, etc.

 gathering food, and hence the case terminates in starva-

Treatment. — The success attending the treatment of 

 such cases is very great. The cure consists in finding 

 out the exact spot on the head over the hydatid, and 

 bore through the bone with an instrument made for that 

 purpose. And as soon as the bone is bored through a 

 small pair of forceps or tongs is put through the hole, 

 and into the sack, and by this means together with a 

 syringe with a long nozle to pump out what fluids there 

 are in the cavity, complete the cure. The hole of 

 course will have to be closed by a pad or cloth, to ex- 

 clude the air till the hole have closed by a new bone. 



Inflammation. — Inflammation is the same in all 

 animals, but happily it is not common to the ox tribe. 

 Indeed inflammation in all animals is not so common as 

 it is used or, is represented to us to be. Irritation is 

 more often observed among animals and men, than in- 

 flammation, and disease with decreased force or power is 

 more frequent than either diseases now a days or, it
