tion of the foetus, and I left her quiet in the evening with a per¬ 
son to watch all night, and to call me should any change take 
place. I did not see her again until about a quarter before six 
next morning, when I found her standing quiet, and was told 
she had been so nearly all night, excepting now and then a 
spasm. The pulse was much quickened, and the extremities 
colder. The vulva was very considerably swollen. I then de¬ 
termined on the extraction when the other horses had left the 
stable, which were at that time harnessing, and went home for 
something which I might require. On my return, I found she 
had dropped and died suddenly. On opening the abdomen 
there was . no appearance of peritoneal disease. I opened the 
womb, and took out a lifeless colt : there was nothing like 
inflammation, but my assistant, in pulling out the intestines, laid 
hold of a hard body in the rectum. He cut down upon it, and 
took out the largest concretion, measuring nearly thirteen inches 
round (the half of each I have sent, thinking they may be worth 
a place in your museum). The inner coats of the part much 
inflamed and ulcerated, but not ruptured. A piece of iron was 
the nucleus in both. You will find the nucleus in the larger 
specimen ; the nucleus of the smaller was a piece of a nail, but, 
leaving it with a surgeon of this place, it was lost. They must 
have been sucked up in drinking from a puddle, when in extreme 
thirst, the earthy matter derived from the corn.

Gentlemen, —When I first proposed to bring under your 
consideration “ the Diseases of Joints in the Horse, v I was not 
aware that Mr. Turner intended to read his paper so early on 
the treatment of a disease, that would otherwise have furnished 
me with a principal subject for remark ; however, as circum¬ 
stances have occurred to prevent the full discussion of the va¬ 
luable result of Mr. Turner’s experience in the disease alluded to, 
I feel that we should not be doing him justice did we not afford him 
an opportunity of collecting the sentiments of the members of the 
Veterinary Medical Society on the nature of the navicular dis¬ 
ease, and the peculiar treatment which he has recommended. 
There are two joints in the horse whose diseases, when con¬ 
firmed, baffle all our veterinary knowledge. I allude to the
