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.
