 distemper, and is there noticed. In virulent canker, the internal 

 and sometimes the external ear also becomes attacked with exten-

 the dog. The eyes become frequently ulcerated in distemper ;

The Main is an ulcerous affection of the sides and under sur-

 often attributed by country people to being poisoned with eating 

 some herb, or by killing a toad or serpent, or by other equally 

 sapient causes. It is sometimes attended with constitutional dis- 

 turbance ; at others it interferes but little with it. In the former
