REPORTS OF CASES. 
OBSTRUCTION OF THE DUODENUM BY CESTRUS EQUI. 
By H. N. Walter, Y.S., Windom, Minnesota. 
As a fatal termination from the presence of bots in the 
stomach of the horse seems a very rare occurence, (Prof. 
Williams in his work on Equine Medicine, only referring to 
two cases) the following may be of some interest: 
The patient was a two-year-old gelding, in rather poor 
condition. When first seen by me showed the following 
symptons: Pulse about 60 and strong, breathing much accel¬ 
erated, pawed incessantly, turning the head around and look¬ 
ing at his side as if suffering from colic. On every attempt 
to pass foeces groaned with agony, and when the rectum was 
emptied by hand a small amount of soft dung, with a very 
rotten odor, was found just anterior to the fundus of the 
bladder and immediately above the ureters, the pressure of 
the fingers in that locality causing acute pain and straining. 
Frequent attempts were made to urinate, what little was 
passed being highly colored and extremely viscid, very much 
resembling syrup. After twenty-four hours this urine 
deposited a thick sediment. 
Treated with hypodermic injections of morphine, hot 
cloths to the loins, demulcent drinks and a laxative, the 
urgent symptoms would abate for about twelve hours and 
then return with renewed violence; the patient, in the inter- . 
val, eating readily, and the pulse almost regaining its normal 
condition. For several days no foeces were passed volun¬ 
tarily, and only very small pellets could be reached by the 
hand, but even these, by pressing on the fundus of the bladder, 
seemed to cause acute pain. On the fourth day a violent 
diarrhoea set in which lasted until the ninth day, when the 
pulse being almost imperceptible and pain intense, we put an 
end to his sufferings. 
The post-mortem examination showed the large intestines 
united to each other and to the abdominal walls by numer¬ 
ous adhesions, the walls of the bladder enormously thickened, 
presenting a thick mass of tissue, pale yellow in color, and 
very friable. Before removing the stomach, I tied two pieces
