One fact in taking the temperature: make all the cattle stand 
as all cattle defecate shortly after rising. This will probably 
save you many thermometers. The preparation of tuberculin is 
accomplished in the following way by me :— 
181-2 drams of i° solution of carbolic acid, using distilled 
water, and one bottle of Koch’s tuberculinum which makes 20 
drams of solution, I inject from twenty to sixty drops according 
to age and size of the animal. Injection to be made in centre of 
the shoulder. In cows you suspect of chronic tubercular mam- 
mitis, be sure and use the full dose, as they are hard cases to get 
reaction. 
The question has arisen in regard to at what rise we shall 
consider a cow tuberculous. In the year 1892, we, as Inspec¬ 
tors of New York State, were instructed not to kill any cattle 
unless we had a rise of 21-2° or upwards, but I am frank to say 
that many cases of tuberculosis were left behind to which I have 
since been called to kill and hold post-mortem and found them 
tuberculous. I have found where there has been a steady rise 
of i° or upwards, these cattle are very suspicious and generally 
are tuberculous. I should strongly advise to isolate them for a 
second investigation. 
The total number of animals which I tested up to August 
27, 1894, was eight hundred and sixteen heads,, and out of this 
number three hundred and fifty-one have been killed and post¬ 
mortem records kept of same. Out of three hundred and fifty- 
one killed there were six which did not react, but were killed on 
the strength of a difference of opinion. In five of these cases 
there was pneumonia. The sixth one had a very marked dull¬ 
ness of one lung, a cough, and also emaciated. We found a 
piece of wire had penetrated the lung. 
Out of three hundred and forty-five cattle which reacted, I 
have to record one failure, that of Mr. J. Gilbert’s. The only 
thing found diseased in this cow was where wire and nails had 
penetrated the paunch. At this place there was a hardened 
bunch, which might have shown the tubercular bacilli if exam¬ 
ined with the microscope. I have had a very narrow escape of
