mortem and post-mortem determination, I might state that it 
it altogether probable that there are many cases of mammitis 
which result in what is popularly known as spoiled bag, which 
are not tubercular. The udder, one or several quarters of it, 
may be involved, but is usually involved as a whole, and upon 
palpation presents quite a uniform surface, which is quite 
dense, and in these cases there is no characteristic enlargement 
of the lymphatic glands above and behind the udder, while in 
cases of tubercular mammitis tubercular masses are developed 
in the substance of the udder, usually so pronounced that they 
can be readily determined by palpation ; also there is involve¬ 
ment of the supermammary lymphatic glands. I do not know 
that it is common to find a tubercular udder in which the 
tubercular process has resulted in the formation of abscesses 
such as have been described. However, there are so many 
things with which I am not familiar which are facts, that I 
would not undertake to say the case described is not tubercular. 
Certain it is that it would be good policy to test a case of that 
kind with tuberculin, and in that manner pass upon the 
question. 
Dr . Wilson ; Down here we get many cases of that kind, 
almost every day, in fact, and we pass them along unless they 
show other symptoms along with the enlargement, where the 
udder has had little abscesses form from split bag, and upon 
post-mortem examination they show no sign or trace of tuber¬ 
culosis in most cases. 
Dr. Cooper : I had a case last summer at the packing house 
of Schwarzchild & Sulsberger, at Kansas City, the first I no¬ 
ticed. The udder showed quite a large abscess and tubercular 
indications all around it. I told the boys to be careful and save 
the guts and everything of that kind. When the animal was 
hung up it showed no great emaciation ; lungs were found to 
be very bad, and intestines, liver and ovaries badly involved. 
In fact, the whole system was about as bad as I ever saw. She 
was not fat nor yet what you would call thin, and probably 
would be passed as a cow with split bag. This large abscess 
would probably hold half a teacupful in one side of the udder, 
the other not quite so much, of quite soft pus which flowed 
readily, and which did not have the usual appearance of pus, 
which you will see in tuberculosis—different color somewhat, 
and a great deal thinner.
