This treatment usually palliates the lameness. Should it not 

 do so, the owner must be patient, and give Nature time to restore

 or front part of the hock, and sometimes there is no enlargement 

 to be discovered. Such cases, unaccompanied by enlargement, are 

 called inter-articular spavin.

 practiced in such matters. Lameness, however, the effect of 

 spavin, may be present without any detectable tumor. 



My own observation has led me to note two kinds of lameness 

 in spavin— one, the effect either of the ordinary subacute or chroilic 

 inflammation, or of partial anchylosis of the parts, is but compar- 

 atively slight, and consists, for the most part, in stiffness on motion,
