This treatment usually palliates the lameness. Should it not 

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

 Such agents are always indicated in the treatment of the above 

 malady.

 circumscribed spheroid tumor, of the magnitude of half a walnut 

 or more, is evident enough both to the sight and feel of the man 

 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 chronic 

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

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