UNUSUAL APPEARANCE OF THE URINE. 435 
was led out of the stable she appeared in perfect health, and 
very playful, so much so that the horse-keeper could scarcely 
keep his seat. She had proceeded about half a mile when she 
suddenly stopped, began sweating and trembling without any 
apparent cause, and was with difficulty led home : I was im- 
mediately requested to see her. 
I found her sweating and trembling, and scarcely able to turn 
in the stall ; her pulse was 75, and hard ; the muscles on the back 
and loins in a state of spasm, and her tail quite stiff'. She kept 
looking at her flanks, and appeared to be in violent pain. When 
she was forced to go in a straight line she dragged her hind legs 
after her, but her loins did not appear tender when pressed upon. 
I passed the catheter into the bladder, and about a pint of fluid 
of the colour and consistence of linseed oil escaped ; after that, 
about the same quantity, and a little thicker, of the colour of 
porter ; and a third portion of the colour of milk whey. 
I took five quarts of blood from the jugular vein ; gave 3 vi ij 
of aloes in solution, with ^viij ol. lini. in a drench, and 
applied a mustard poultice to the loins : she was rubbed dry, 
and her legs flannelled. The catheter was passed about four 
hours afterwards, and nothing escaped but gas : a bran mash was 
given with linseed, which she ate, and she was allowed linseed 
tea to drink. 
2lst. — She moves better ; pulse (JO, and soft ; bowels open ; 
the poultice acted well. The muscles of the back, &c. are nearly 
in their natural state. No medicine. 
22 d . — Going on well ; keep her chiefly on linseed mashes and 
tea. 
23 d . — Still going on well. I gave her a ball composed of 
pulv. zingib. sij, pulv. gent. sij. 
24^/*. — Quite well : went to work a few days afterwards. I 
imagine that she must have ruptured some of the small vessels in 
the kidneys, in the act of playing : but what was the reason of 
the different colours of the urine, and why it did not mix in the 
bladder, I do not understand. You will please to observe, that 
it was all taken at one time; that is, the catheter was not with- 
drawn until the three different colours were taken away. 
Your opinion of this case, or that of some of your correspond- 
ents, would be thankfully received.
