There is often lameness, and an offensive smell from 

 the affected frog, in some cases it has a cheesy -like ap- 

 pearance; if the frog is allowed to spoil under the condi-

 out once daily; if thrush is present, after cleansing the 

 part and cutting away the diseased portion, press in burnt

Coffin joint lameness, navicular disease, is a disease of 

 the coffin joint, and its cartilages, which comes on slowly, 

 usually the result of concussion, more especially if the 

 foot is not a strong one and of good shape, shoeing with 

 high heels, thus relieving the frog from pressure, will
