The wall at the toe, which was previously but little altered in 

 form, is now tlirust prominently forward. 



The inflammation of the j^ododerm may under certain con- 

 ditions and by skilful veter-

 so that the characteristic 

 changes of form and quality 

 of the hoof will not occur. 

 But if this is not accom-
