134 DISEASES OF THE GRPIYHOUND.

 the abdomen (peritonitis), or may comprehend both. But no 

 amount of practice can do more than enable us to guess, by the 

 severity of the attack, as to the precise seat of the disease. Of 

 course the larger the extent of surface inflamed, the more severe, 

 cceteris paribus, will be the symptoms. For this disease large 

 bleedings are requisite, and they should be carried to fainting ; 

 after this, calomel and opium in grain doses may be given every 

 three hours, and, if there are conveniences for the purpose, a 

 warm bath will be beneficial, using every precaution to prevent 

 cold afterwards. After giving the calomel and opium for twelve,

 must be repeated, or, if it is relieved, a dose of castor oil may be 

 given. If the rectum is full of impacted faeces, which may easily be 

 detected by examining the flank, an injection should be thrown up.

 the pain is intense, but intermits; there is little fever or altera- 

 tion of pulse, but the bowels are obstinately costive. The pain 

 is so intense as to cause the dog to cry out when it comes on, but 

 in the intervals he will come out of his bed and appear much as

 which arises from the irregular contractions of a portion of the 

 intestine, by which it is forced on into the expanded, or rather 

 the uncontracted, part immediately below it. Sometimes I have 

 seen ten or eleven inches of intestine thus doubled by its own 

 peristaltic action. No symptoms during life will serve to distin- 

 guish this accidental accompaniment of colic, for constipation is
