We cannot tell with certainty that 

 strangulation has taken place ; but we 

 may expect such to be the case, when 

 we find that symptoms of colic con- 

 tinue without remission in spite of all 

 our treatment. The pulse in these 

 cases is not quick at first, nor for 

 several hours afterwards ; but the pain continues to increase, 

 and at length inflammation supervenes, and the horse continues 

 in the greatest agony for ten or twelve hours, when the inten- 

 sity of the pain seems to disappear, but the animal dies a few 

 hours afterwards. 



It is a disputed subject whether intervagination is more fre- 

 quently the consequence of the spasmodic action and commotion 

 of the bowels in colic, or whether the twisting of the intestines 

 occurs previously, and is itself the cause of even the earliest 

 symptoms that are manifested. We have no means of demon- 

 strating which theory is correct ; but I am inclined to consider 

 that although intervagination may be sometimes the eflfect of 

 colic, it more frequently arises from one gut getting accidentally 

 entangled in the other when in an emj)ty state, and producing
