from a bucket. It drank A. m. and p. m. its mother’s milk con¬ 
stantly mixed with other milk, very rich in bacilli, which was 
supplied by cows No. io and No. n. This young animal has 
always been in good spirits and a vigorous appetite. 
Its temperature remained normal until June 26, wnen it 
was 39 0 .1. June 27, the day of the last tuberculin test, it was 
39 0 .3 ; then the next day, the 28th, there was a thermic and 
organic reaction, with the iollowing temperatures : 6 A. M., 
4o°.3 ; 9 a. m., 4o°.5 ; 12 m., 4o°.8; 3 p. m., 4o°.8 ; 6 p. m., 
40°.6. June 29, in the morning it was 39 0 .8, evening 39°.6. 
July 1st it had gone down to normal, 38°.7. 
The organic reaction was manifested by dejection, great 
prostration, complete inappetency, general trembling, continu¬ 
ous moans and an intense lameness of the left fore leg, back of 
which shoulder the injection of tuberculin (2 cc.) had been 
practiced. June 29th all traces of organic reaction had disap¬ 
peared. 
From the 26th of May this calf was submitted, together 
with all the other animals, to the tuberculin test, and the quan¬ 
tity used was 2 cc. It did not cause a reaction until June 27. 
Tne last contaminated meal was taken June 9. The minimum 
duration of the incubation was 18 days. 
It is important to notice that this calf showed some hyper- 
thermy on June 26, 39 0 , 39°.i, and on June 27, 43 0 .3, before it 
received the injection of tuberculin. 
Autopsy. 
The mouth, the velum of the palate, the pharynx, the larynx, 
and the trachea are sound, so are the sub-glossal glands ; only 
one retropharyngeal gland on the right side shows in its ante¬ 
rior lobe a small yellowish focus of a tubercular nature. 
The pulmonary viscerse are sound. All the ganglions of the 
concave side of the intestines seem to be hypertrophied. The 
first ganglion of the chain show quite recent tubercular infiltra¬ 
tion. Toward the middle of the small intestine there is found 
another, which is filled with very fine miliary granulations half 
transparent. A Peyers gland is thickened, hardened, but not
