508 DISEASES or THE UDDER AND TEATS IN COWS. 
about two inches, and broke down two different pieces of 
coagulum or membrane that crossed it, and the milk could be 
immediately drawn off, and she did well without any further 
trouble. 
Case 2 . — Injury to a Cow's Teat . — 17th Sept., 1845. Mr. 
Garratt, timber merchant, of this town, had a cow that had 
just met with an injury to one of her teats, in having a little 
of the end of it cut off slantwise. Although we fomented the 
parts, bled her, and repeatedly passed the silver milk tube up 
it, yet she became “gargated,” and lost her quarter. 
When the teat is injured, we scarcely ever do any good. 
At first the milk becomes obstructed in the teat, and by the 
introduction of the tube, the teat, and ultimately the udder, 
becomes inflamed. Then scarcely any milk flows, and what 
comes is frequently bloody, but soon it entirely ceases. Now 
only some serum can be drawn out, and soon this ceases. 
Next, pus forms, and which comes out in clots, at others it 
is tolerably liquid ; and if it cannot be well got out, the udder 
hardens in places, and abscesses form, and now the udder is 
completely destroyed for secreting milk, and she is com- 
pletely “ gargated.” 
In April, 1846, this same teat again became highly inflamed 
and swollen, and pus formed within it. I inserted caustic 
lints in its orifice, which was nearly closed up ; a slough came 
out, and the pus discharged well. Abscesses afterwards 
formed in the udder, which (the abscesses) ultimately got well, 
but the udder became scirrhous. 
CaseS. — Obstruction in a Cow’s Teat . — April 17, 1844. Was 
sent for to attend a cow that had calved yesterday ; no milk 
could be got out of the anterior off teat. On examining it, I 
found that at about an inch and a half up it, there was a 
thickening for about half an inch in length of the lining 
membrane, and no doubt the sides of which were united, and 
the passage was completely obstructed. I first passed a 
probe, and forced it through, after which, I passed a silver tube 
up it, and then the milk ran freely and relieved the udder. 
On the 18th and 19th, I introduced the tube pretty easily, 
and the milk ran through it readily, and I was in hopes that 
the tumour, a “thunk,” as it is called about here, in the 
passage would become absorbed. Some of the milk could 
be drawn by the hand after the tube was removed. 
20th. — I introduced the tube again, but no milk came out. 
The teat was sore, and from the orifice a little blood oozed 
out. To be left alone. 
21st. — The teat and udder were much sorer, and the orifice 
was closed up and swollen, and a little blood oozed out. With
