28 COLICS AND THEIR TREATMENT 



1. — New Growths, Foreign Substances, Etc. — 



Foreign substances, including calculi, hairballs, sand, 

 gravel, or other extraneous and indigestible materials, 

 growths in the form of tumors or abscesses seldom give 

 rise to signs having any definite diagnostic value, and 

 oftentimes it is only through postmortem examination,

 conducive to periodic attacks of enteralgia. 



At such time a review of the case furnishes sufficient 

 information to substantiate the belief that intestinal 

 trouble has existed for a considerable period; the his- 

 torical resume of such cases show that the horse has not 

 been, in most instances at least, an easy keeper, has in-

 been as spontaneous in their disappearance as unaccount- 

 able in origin; straining intervals, with periods of con- 

 stipation are not infrequently followed by diarrhea. 



Should an abscess develop well toward the rectum, 

 switching and restlessness of the tail and general un-

 my observation and that had its origin as a result of mal

 alysis, particularly when involving the lower bowel, has
