OBSCUKK DISK ASK IN A HORSK. 685 
On auscultating the chest, 1 found the principal obstruction was 
at the larynx. I bled him largely — liquid blisters were rubbed 
on the thigh, and he was afterwards physicked. 
The cough still continued, therefore I introduced a seton under 
the jaw. He was taken again to my stable, to have setons pass- 
ed through the hocks, for there was some engorgement there. 
All did well. He was then put to grass by day, and taken in at 
night. 
A few days after, he was exposed to a shower of rain. A trem- 
bling fit came on, but soon passed off when he was taken to the sta- 
ble. Afterwards diarrhoea made its appearance, of black faeces, and 
had continued a few days, when 1 examined the rectum. It had a 
scirrhous feeling, with thousands of concretions, which could be 
detached by the finger and thumb. I cannot describe them more 
faithfully than by saying that they resembled dried mortar, with 
a yellow tint. I also felt one of the small intestines considerably 
enlarged, and the coats much thickened and hot, from two to 
three feet in extent. The dung was in a very liquid state. 
On introducing Head’s stomach pump, which I prefer to the 
pipe — for with the arm in the rectum it can be introduced into the 
colon seven feet and more, and if an assistant is not at hand I then 
tie the tube to the root of the tail — I found some of the concretions 
attached to the bulb of the tube, from which I concluded the 
colon was in the same state as the rectum. 
The dung was now of a black colour, with a quantity of bloody 
mucus. From the manner in which he curved his back, I am 
led to think there is adhesion between one of the intestines and 
kidneys, for I have seen such symptoms in similar cases. I can- 
not, how'ever, detect any albumen in the urine, which I believe 
is the case when that organ is affected : but I have detected it 
when that organ has not been affected, particularly after a hard 
day’s hunt, or in dropsical affections. I have been in the habit 
of drawing off albuminous urine after violent exertion for twenty- 
five years. Before he had this attack he brought away large 
quantities of phosphate and carbonate of lime, as I have before 
described in The Veterinarian for May 1840, for which I 
gave the same remedies as there named. This horse, to my know'- 
ledge,has never had the strangles. 
1 beg to submit to your examination a few of the extracted 
substances taken from the ulcers in the rectum. I have had 
them analyzed by a chemist, and the following are their differ- 
ent proportions: the sabulous deposit in the urine consists of 
phosphate of lime with slight traces of the carbonate of lime, and 
the small excrescences obtained from the intestines are portions of 
the ulcerated coat.
