OTHER FORMS OF HERNIA.
The other forms of hernia (umbilical, inguinal, scrotal, femoral, ventral, vaginal, ischiatic) are essentially surgical and need not be further referred to here, than to guard the reader against overlooking them as factors in producing intestinal and omental strangulation and colic. They are all to be recognized by the presence of a local swelling, which may often be obliterated by returning its contents into the abdominal cavity, which sensibly enlarges when the animal is made to cough, and which, if made up of intestine, is subject to gaseous distension, and gurgles when manipulated and returned. A violent colic occurring in a male animal should never be considered as certainly diagnosticated until the scrotal and inguinal region have been carefully examined for hernia.
