SWELLING OF THE UDDER OF A COW. 255 
thinking it a fair case for the trial of iodine, I determined upon 
using it; but the difficulty of swallowing preventing me from 
giving it internally, I depended upon its external application in 
the following form : tr. iodine ^\j lin. saponis ^ii, to be rubbed 
in twice a-day. 
Sth .—Mare looking much better ; has eaten some green clover ; 
breathing much improved ; the glands, I think, feel somewhat 
softer : continue the linament. 
12th .—The mare is much improved in appearance, and breathes 
without difficulty. Thinking she could now breathe without the 
canula, I took it out, and closed the opening with my fingers. 
The breathing became oppressed, and the anxiety of counte¬ 
nance returned: I therefore replaced the canula, and ordered 
tr. iodine jii, c. lin. sapon. Jii, to be applied as before. 
16^//.—The glands have become softer, and much reduced in 
size. I again removed the canula, and found that the mare 
breathed without difficulty: the wound to be daily dressed with 
sol. chlo. calcis., and the glands embrocated as before. 
From this time my patient rapidly improved in condition, and 
the glands soon regained their natural size and appearance. 
The mare has since been engaged in fast work, which she per¬ 
forms without any apparent inconvenience. 
A CASE OF SWELLING, AND INDURATION OF THE 
UDDER OF A COW, 
SUCCESSFULLY TREATED IN THE SAME MANNER. 
Bj/ Mr. Charles May, V. S., Maldon. 
The next subject upon which I tried iodine was a milch cow, 
the property of Mr. Bryant, of Woodham Mortimer, near this 
place. The owner informed me, that she had had a large hard 
swelling in her bag for more than a twelvemonth, which had 
increased of late, and that she had lost the milk from one quarter. 
When I saw her, I found the udder on the right side very 
much enlarged, and hard ; she also expressed pain upon pres¬ 
sure. I ordered tinct.iodine 5ii, lin. sapon. 5ii, to be well rubbed 
on the part twice a-day. This treatment was continued for about 
three weeks; the swelling gradually became reduced, and the 
secretion of milk much more abundant, and it returned to the 
quarter which had become dry. 
Iodine has had but little trial in veterinary practice. I do not 
remember to have heard it even named by either of the Profes¬ 
sors at the Veterinary College ; it promises, however, to be a 
valuable^addition to our pharmacopeia, and especially when we 
have these glandular enlargements to contend with.
