DISEASES OF THE UDDER AND TEATS IN COWS. 509 
some little trouble, I again introduced the silver probe, and 
milk passed very fluently. I forgot to observe that this cow 
was bred by the owner, and that nothing had ever been amiss 
with her teat before, and she was well when she was 
loosed dry. 
29th. — The milk has been got out very well, and the 
udder is very soft ; but, from some cause or other, the teat is 
now a good deal diseased, as it is difficult tointroduce the tube. 
Pus and serum are now within it. The tumour in the teat 
is as hard as ever, and the tube is obliged to be still forced 
through it. I fancy the teat has become inflamed from 
rubbing some Ung. Potas. Iodid. on it and the udder, and 
from another person forcing the tube up. This case I left off 
attending in consequence of other interference; abscesses 
formed, and she lost the quarter. 
Case 4. — Obstruction in a Cow’s Teats . — 13th April, 1844. 
I was sent for to a cow that had been purchased at our fair 
on the 11th inst., that had got obstructions in two of her 
teats ; she had calved two or three days before she was 
bought ; no milk could be got out of the hinder teat on the 
off* side, or any out of the anterior one on the near side ; the 
obstruction was about half way up in each teat, and I could 
not pass even the silver probe through the off* teat. I did so 
in the other, but could not, on account of the smallness of the 
orifice of the teats, introduce the silver tube into either of 
them. Both quarters took good w T ays, and nothing more 
was done but fomenting, drawing, and hand-rubbing the 
teats and udder, which became quite soft, and the milk flowed 
out well. 
Case 5. — Obstruction in a Cow’s Teat . — June 6th, 1843. 
Mr. Green, shoemaker, of this town, purchased a cow at our 
late fair, and at the time of purchase, her udder was freely 
distended with milk ; at night she was milked, and it was 
found that from only three of the quarters could the milk be 
entirely drawn off*. From the other he could only extract 
about half a tea-cupful, when it would cease, but in a short 
time the lower part would be filled again, and in the same 
way only a similar quantity could be obtained. The owner 
took her again on my pronouncing her unsound. 
Observations . — The obstruction in this case lay at the upper 
part of the teat, and there must have been a stricture there, 
as there was only a small orifice to admit the milk through. 
I could not detect any thickening or tumour about the 
parts. Not near all the milk was obtained from the quarter, 
yet it was not coagulated. 
Case 6 . — Obstruction at the ends of a Heifer's Teats . — 18th
