saw her last, improving in condition, and has not strained so 
much. Latterly she has been observed to be in aestrum. 
This day 1 thought proper to tap her although there was 
nothing to indicate a great accumulation of fluid, yet I drew 
away about five quarts, though I think it was not so offensive 
as before. 
28th. — I understand she has been straining a good deal 
lately, and this day 1 was sent for. Her general appearance 
is good, but she has not improved in condition so much as 
expected, considering she has been put up to be stall-fed. The 
vulva is well contracted, and there is not the least swelling 
about it or the anus. On putting my hand up the rectum I 
found the uterus was very much distended, but I could not 
detect the existence of any foetal bones. On introducing my 
finger into the os uteri I found it was more thickened than 
formerly. I then introduced the catheter and I drew off 
about six quarts of fluid ; but this time I found it very much 
altered in colour, being a light brown, and it evidently con- 
tained small masses of coagulated pus, and its smell was more 
offensive. Gave a solution of opium to allay the straining. 
Soon after this the [animal, being in good condition, was 
sold to the butcher, and, I am sorry to say, I had not an 
opportunity of making a 'post-mortem examination of so rare a 
case. 
Observations . — I cannot at all say what could be the cause 
of this disease. She never had a calf. A bull was in the 
stock but he was not diseased. One can hardly fancy abscesses 
had existed and burst so often in the uterus. The pro- 
bability is that the lining membrane was in a diseased and 
ulcerated state, and secreted the sero-purulent matter.

PATHOLOGY OP LAMINITIS. 
By T. Greaves, M.R.C.V.S., Manchester. 
( Continued from p. 383.) 
I now approach the most important part of my subject; 
and, from the positions I have advanced in my former papers, 
it will be observed that I class this disease under two heads : 
the first I shall designate passive or undeveloped laminitis, 
and the other active or developed laminitis.
