DISEASES OF THE HOG. 59 
Cases may occur in which a drastic purge will be 
necessary; in such cases give from two to three 
drops of croton oil in a little castor oil or sweet 
oil. There are a number of other purgatives which

and will prevent constipation. It is also good for 
grown pigs. <A teaspoonful of white mustard seed 
and a little hardwood charcoal is a preventive.

This term is applied when some mechanical im-

idea that it might be “hog cholera.” On post mor- 
tem I found a portion of the ileum near its entrance 
into the cecum filled with cinders and that portion 
of the bowel swollen and black, and I have no 
doubt but that hundreds of pigs die from this 
cause. Solid concretions sometimes form in the 
bowel. There are also strictures which take place,
