llie skin inflainod and sloughed, ■while the dark parts were 

 unchanged. Tliis peculiarity can scarcely be said to apply to 

 the disease as it manifests itself in this country, wheje colour 

 or the -vvant of it does not affect its course and progress. 1 have 

 repeatedly seen it in sheep, as well as in cattle and' horses, fed 

 on certain clovers, which seemed to excite the disease m5re hy 

 being brought into contact with the sldn than by any effect upon 

 the general constitution ; the eruption being confined to those 

 parts of the body which were continually touched by the 

 [herbage, namely, the lips, nosti-ils, coronets, and pasterns. 



Treatment. — The removal of the affected animals from tlic 

 field containing the cause will generally be sufficient ; but should 

 surgical interference be req\iired, the parts are to be rubbed over

 the symptoms, and by the particular cause and locality of. the 

 disease. When it is of constitutional origin, purgatives are to
