CALCULUS IN THE TEAT OF A COW. 
571 
' Rumination had ceased some days — she refused all solid 
food, and cared little about that which was liquid, except that 
she would take a little cold water. My first opinion was that 
she had taken cold, and that the affection of the udder was a 
symptom of this, rather than a disease of itself. 
I abstracted six pounds of blood from the milk veins, and 
prescribed a decoction of marsh-mallow leaves, linseed, and poppy 
heads, by the mouth and by injection, with frictions of the 
populeum ointment on the teats. 
II th . — The symptoms unchanged, except that the teats are 
more swelled. On accidentally touching the udder, I fancied that 
one of the teats contained a hard substance within it. I intro- 
duced a sound, well oiled, into that teat, and it soon came upon 
a hard body. I endeavoured to detach it, by introducing the end 
of the sound between it and the side of the canal : but, failing in 
that, I secured the beast without casting it, and then, while 
an intelligent assistant dilated the orifice of the teat, I endea- 
voured to urge it on by compressing the teat behind, and imi- 
tating the act of milking, until at length I forced it through 
the orifice. The milk immediately flowed abundantly, but 
from that teat alone. The treatment of yesterday was ordered to 
be pursued. 
The calculus was about the size of an ordinary nut, of an ob- 
long form, a yellow colour, and very hard. I crushed it with a 
hammer, and found that its colour was deeper at the centre than 
on the outside. It effervesced with sulphuric acid, yellow 
vapours having a peculiar odour escaping. 
During four-and-twenty hours, the milk ran spontaneously 
through the teat which had been obstructed. The others, on 
being drawn, yielded a milky fluid mixed with blood. The 
swelling of the udder gradually diminished. The appetite 
began to return, and I permitted them to give the animal its 
ordinary food, after it had been kept six days on gruel. Emol- 
lient drinks were still given, and fomentations applied to the teat, 
from which the scarf-skin peeled quite away. 
At the expiration of eight days, the animal appeared to be 
well, and yielded as much and as good milk as it had been 
accustomed to yield.
