 though he may appear, there is every excuse for the 

 veterinary surgeon. 



Once the cavity is opened at the toe in the neighbourhood

In Fig. 130 it will be seen that the disease commences at 

 the plantar surface of the toe, and extends upwards and 

 inwards. The same condition may also appear anywhere 

 between the coronet and the ground, gradually extending 

 into the substance of the wall, as shown in Fig. 131. 

 According to the writer. Colonel Nunn, the progress of the 

 disease in this latter case appears to be faster in a downward
