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 

 are useful. The compound cathartic pill is very

 of iron and two to three grains of nux vomica at

 and will prevent constipation. It is also good for 

 grown pigs. A teaspoonf ul of white mustard seed 

 and a little hardwood charcoal is a preventive.

 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,
