SPATIN _ 503 



upper surfaces of the cuneiform parvum / and the cuneiform 

 medium c. This form of the malady is designated "High 

 Spavin," in contradistinction to the other. It is a worse con- 

 dition of the disease than the former. The animal is more 

 acately lame : the chances of cure are more remote : and it is 

 far more Hkely to involve the other bones and articulations of 

 the joint. 



Symptoms. — Having briefly described the seat, and also 

 explained to some extent the mode in which certain causes 

 operate ia the production of Spavin, I will now detail the 

 symptoms of the disease. 



The symptoms during the early stages of the malady vary ; 

 in some cases the enlargement of the hock precedes lameness ; 

 and in others lameness precedes the enlargement ; and some- 

 times large bony protuberances of the hock upon the seat of 

 the spavin are met with without lameness as a result thereof 

 having ever existed. Cases of this kind, however, comparatively 

 speaking, are not common. The joint afiected will be of a 

 higher temperature than ordinary. At first the animal will 

 move the limb stiffly ; but the stifihess will disappear as the 

 joint is brought more into play. As the disease progresses 

 the animal will become decidedly lame, and the lameness more 

 confirmed, and of a character more pathognomonic of the struc- 

 tures diseased. The hock wiU increase in size ; the patient, if 

 made to travel,' will step upon the toe and upon the outside 

 quarter of the foot ; he will avoid flexing the hock ; the limb, 

 during the act of locomotion, will sometimes be carried out- 

 wards and forwards, and sometimes inwards and forwards ; and 

 the toe, to some extent, will be trailed upon the ground. 



Tebatmbkt. — The best remedies and modes of treatment 

 in general are — a high-heeled shoe, Mring and Blistering the 

 hock, and allowing the patient a long rest in a loose box.
