SCROFULOUS OSTITIS. 173 



siderable amount of pain is manifested by the animal ; there 

 is lameness if in one of the bones of the limbs, where it 

 usually is, and there is usually a circumscribed enlargement 

 of the bone, not nearly so well defined, however, as an 

 ordinary splint. This spot on manipulation is found to be 

 very sore, the animal showing a strong objection to having 

 the parts handled ; a bone abscess is, however, as a rule, 

 pretty difficult to diagnose. 



Treatment. — Having located the abscess, it is to be opened 

 by trephining, when, if the case has been correctly diag- 

 nosed, the imprisoned pus will escape, and relief will be in- 

 stantaneous. 



Scrofulous Ostitis. — This disease is most commonly met 

 with among calves, foals, and other young animals. 



Causes, — Scrofulous ostitis is caused by an insufficient 

 supply of milk being given to the young animal ; it may be 

 due also to a naturally weak constitution. Where horses are 

 allowed to serve a large number of mares, the foals often 

 have this disease. It occurs now and then in a colt that 

 apparently is perfectly healthy. 



Symptoms. — The symptoms are usually well marked : 

 when down the animal has considerable difficulty in rising, 

 the articulations become swollen, and on making an 

 examination of the parts they are found to be very painful ; 

 soon the joints become very much enlarged, in some cases 

 so large that both hands will not reach around ; pus is 

 formed in considerable quantities, and usually the sufferer 

 dies. 



Treatment. — In some cases it may possibly be overcome. 

 Give good food, quietude, and gently stimulate the parts. It 

 usually is connected with the stifle, hock, knee, etc.
