INTERESTING TUBERCULIN REACTIONS.

fifteen, or 66^ per cent., gave evidence of the disease. Whether 
the percentage of the animals affected in the incipiency 
of the disease in the two barns in this case had any connection 
with or relation to the sanitary conditions of course cannot be 
positively stated ; however, it' looks very suspicious, as there was 
more or less irregularity in the temperatures of nearly all the 
animals in barn No. i. The reactions in No. 2 were nothing 
out of the ordinary. In No. i the most conspicuous were the 
following three : 
No. 482, Shorthorn, weight 1050 lbs.; temperature before 
injection, Oct. 27, 10.30 A. m., 102.i ; 2.30 p. m., 102.2 ; 5 p. m., 
102.2. Injected at 7.30 p. m. Oct. 28, 8 a. m., 106; 10 A. m., 
105.4; 2 P. M., 98.1 ; 4 p. M., 100.2—a maximum increase of 
3 - 3 °- 
No. 487, Shorthorn, weight 1100 lbs.; temperature, Oct. 
27, 10.30 A. M., 101.4; 2.30 p. M., 100.4 5 5 P- 101.2 ; Oct. 
28, 8 A. M., 104.3 5 A. M., 104 ; 2 P. M., 102.2 : 4 p. m., 102. 
Maximum increase of 2.4°. 
No. 492, Shorthorn, weight 1150 lbs.; temperature, Oct. 27, 
10.30 A. M., 102 ; 2.30 p. M., loi ; 5 p. M., 101.2. Oct. 28, 8 
A. M., 103.2 ; 10 A. M., 104.3; 2. P. M., 102.4; 4 102. 
Maximum increase of 2.3°. 
The animals were all treated alike ; injected at 7.30 p. m., 
Oct. 27, and watered at 12 m. In No. 482 the temperature at 
5 p. M., before injection, was 102.2'^; the following morning 
at 8 A. M. it was 106, and at 2 p. m., six hours later, it had 
fallen to 98.1°, or nearly eight degrees, an average of over 
one degree per hour for six hours. The deviations from 
the regular reaction in Nos. 487 and 492 were not quite so 
great. The condemned cattle (the whole number which re¬ 
acted) were shipped to the abbatoirs at the Chicago stock yards, 
Nov. 2d, slaughtered under the direction of the State Veteri¬ 
narian, Dr. C. P. Lovejoy, and the State Board of Live Stock 
Commissioners, and through their courtesy the autopsies were 
held by the senior class of the McKillip Veterinary College, 
under the immediate supervision of the Dean. The results
