EXTRACTS FROM MY CASE BOOK. 
69 
A few days since a cock of mine died of the roop or pip. On 
examination, I discovered a tumour in the windpipe, which I 
supposed was the immediate cause of death. I opened the 
tumour, and found therein a quantity of matter. 
A hen soon afterwards exhibited the same symptoms. I opened 
the tumour, but, thinking any further efforts useless, left her for 
dead, directing the boy to bury them together. Strange to say, 
on my return home in the evening I found her on the roost, 
apparently well ; and she has been doing well ever since. 
As there has been a great mortality among fowls, I think these 
remarks may perhaps stimulate some of your readers to give us 
a little information respecting the diseases of these animals. 
I remain, with sincere good wishes.

LARGE WEIGHT OF SOME CALVES. 
January 29th, 1841 — With considerable difficulty I extracted 
twin calves from a rather small Suffolk cow. They were care- 
fully weighed. The first, five stones one pound ; and the second, 
five stones. Total weight, ten stones one pound. She was six- 
teen days over the medium period of gestation. 
SINGULAR STATE OF THE MAMMILLARY GLANDS IN A COW. 
By the same. 
November 28 th, 1841. — I was called on to attend an eight- 
year-old very fine-looking cow of the short-horned breed for garget, 
if I may so call it. About four years previously, after repeated 
attacks of inflammation of her mammillary glands, she entirely 
lost their natural secretion, and has given no milk during the last 
three and a half years, though in that period she has produced 
three fine healthy calves. After each parturition slight inflam- 
mation of her udder came on, to which my attention was particu- 
larly called ; and now, as on previous occasions, by proper treatment 
it soon subsided, but no milk or any other fluid could be drawn 
by the teats. She appears to enjoy perfect health, and is always 
fatter than the others who are fed in the same manner with herself.
