SUBACUTE OBSTRUCTION OF THE DOUBLE COLON 121 



tereb. and spts. ammon. arom. and a pint of ol. lini. He 

 repeats the ammon. carb., substituting pulv. zingib. for 

 nux vomica in three to four, five, or six hours, if the 

 animal is still in pain, and in the meantime gives 

 frequent hot-water enemas. Should the case tend to 

 become protracted, and the pulse is strong and not too 

 frequent, he injects hypodermically eserine sulph. 

 I grain, and if on the next visit the bowels have not 

 acted, he gives eserine sulph. 2 grains, still continuing 

 the ammon. carb. 



' / have adopted this tveatinent with a little modification with 

 great success} The patients recover much more quickly, 

 and without the nausea and purging occasioned by 

 aloes. I at once inject hypodermically 2 grains of eserine, 

 and give the dose of ammonia and nux vomica in three 

 balls, and leave the draught to be given in two hours. 

 In many cases this has effected a cure, but if there is no 

 improvement in six or eight hours I repeat the ammonia 

 and sometimes the eserine. If the horse is very tym- 

 panitic, I puncture the bowel with the trocar and cannula 

 before injecting the eserine. In several cases in which 

 the first dose of eserine did not give the required result 

 I have repeated the 2 grains in two hours with excel- 

 lent results. / never give aloes nor opium now} . . . 

 Since I have adopted this treatment the horses get 

 better much more quickly. It used to be two or three 

 days, but now I seldom have a case last more than 

 thirty-six hours.' 



The reading of Mr. Harding's paper led me to write 

 asking him to favour me with a short report of some of 

 his cases. He was kind enough to forward the following 

 history of three selected cases of obstruction :
