removed if possible; if this cannot be done the 

 animal should be destroyed. If it is from thicken- 

 ing of the coats, and not too far up, the bowel 

 should be dilated and the enlarged part rubbed 

 with a strong tincture of iodine twice a week. If 

 it should be a tumor either hard (scirrhus), 

 soft, or polypus, it will have to be removed by 

 the knife or ligature. It is a dangerous operation, 

 but it is a case of life or death and ought to be 

 tried. Spasmodic stricture is best overcome by 

 the local use of the fluid extract of belladonna and 

 tincture of opium applied to the inside of the rec- 

 tum once or twice a day. The pig should have a 

 dose of physic, epsom salts is the best, and the 

 feces kept soft by feeding on laxative food. 



HEnORRHOIDS OR PILES. 



This is a term applied to soft tumors which are 

 easily made bleed; these tumors are found in or 

 about the anus. In cases where there is no bleed- 

 ing the affection is called "blind piles." The tu- 

 mors are also divided into internal, those which 

 are within the anus, and external, those which are 

 without the sphincter. Hemorrhoidal tumors dif- 

 fer in character; some are simple and consist of 

 varicose veins in clusters, forming something of a 

 tumor; these tumors are filled with liquid blood 

 and can be easily squeezed out; the others are 

 harder and contain coagulated blood; there is 

 more or less inflammation present and conse- 

 quently an exudation of lymph in the contiguous 

 parts and a soft, spongy tumor is usually the result.
