ON K OF TH E ILL CONSEQU F.NCES ATTFN I) ANT UPON 
VENESECTION IN THE HORSE. 
Dec. 4, 1828.—I was called to a grey colt, four-years* old, ten 
files from hence ; he had been bled about fourteen days previous, 
short time after which it appeared that he had rubbed his 
eck, as there was a thrombus or tumour attended with hsemor- 
hage: a few days afterwards considerable bleeding took place, 
.hich was suppressed by the re-application of pin and tow, but 
ot without some difficulty occurring from time to time upon the 
orse attempting to masticate his food. He was much reduced in 
esh, and on the 4th it was stated had lost two gallons of blood 
t one time, and, the case becoming one of difficulty, I was. 
pplied to. 
Upon my arrival, I found there was an ulcerated opening of 
le vein, attended with flaccidity of the surrounding integuments, 
lough but little inflammation or induration of the tube of the 
ein itself, which is one of the more common ill consequences 
jsulting from the operation. Under these circumstances, willing 
> hope the loss of the vein might be prevented, I applied mo- 
■rate pressure, with tow and a broad crib strap, perhaps six 
iches in breadth, well fitted to the shape of the neck, conclud- 
lg in my own mind, that if at the ulcerated opening, or imme- 
iately below it, there was not permanent obstruction by coagula, 
le blood would flow where there might be the least resistance, 
lat is, along the natural course of the vein, and not out at the 
Icerated opening. The horse ate a mash during my stay, and 
o bleeding took place, so far we appeared to succeed. On the 
th I was sent for in haste, the haemorrhage having recurred, 
decided upon taking up the vein, which I had done in a similar 
lse about ten years previous, and with good success. Having 
ist the horse, 1 made an incision through the common integu- 
lents, about four inches in length, detaching the vein from its 
dlular tissue. I then passed a ligature round it, with a curved 
eedle reversed, holding the point in my fingers and pressing the 
fc foremost, thus answering the same as an aneurism needle in 
ie human subject, and avoiding the risk of puncturing the vein, 
hich might be attended with slight secondary haemorrhage, 
id which occurred to me in my former case. 1 visited him on 
ie 8th ; there was little or no swelling of the surrounding parts, 
hich 1 had advised to be frequently sponged with cold water: 
'-althy suppuration had taken place, and all was going on well. 
On the 12th, the wound was granulating, and looked healthy, 
ie ligature remaining. Did not see him again until the 24th,
