center, showing the joint grown solid. I include an illustration of 

 quite a bad ring-bone, and the same clipped, lined, and also dotted 

 to show how the firing should be done by the pyro-puncturing 

 process. 



At first there may be a somewhat tender and yielding enlarge- 

 ment, which, in the course of time, becomes a hard bony formation.

 appears. 



FIG. 674. As a ring-bone should be fired 

 by the first method. 



Second, the horse may make an effort to relieve the pressure from 



the heels or toe, according to the location of the inflammation. 



Should he raise the heels, then raise the 



heel-calks and round the toe. If on the 



other hand he seems to throw pressure 



upon the heels, then lower the heel and 



round the toe. In the fore feet, at any 



rate, it will be necessary to round the toe 



sharply, which will greatly relieve the 



strain upon the joint by enabling the 



foot to roll easily, or turn upon the toe. 



The best method of doing this is by the 



Roburg shoe, illustrations of which are 



given in " Shoeing," and " Navicular- 



Joint Lameness/' Clip the parts, as 



shown in Fig. 675, then blister or fire, as explained for spavin 



There should be no blistering or firing around the heel under the
