HUMAN TUBERCULOSIS IS TRANSMISSIBLE TO CATTLE.

the day following - , the cornea was opaque, which, however, did 
not prevent the observation of the exudate in the anterior 
chamber for two days. The animal seemed to suffer to the ex¬ 
tent that the appetite diminished. At all times the temperature 
remained normal. On December 19 the condition had become 
worse, the thermometer showed a temperature of 40.6° C., 
which at the night of the same day came down to 40.4 0 C. The 
fever lasted for three days. In the meantime the eye had as¬ 
sumed twice the normal size, so that the eyelids no longer cov¬ 
ered the cornea, which dried up and looked somewhat like 
leather. On the 13th of February the tuberculine test was re¬ 
peated with 0.30 G. Before the injection the mean temperature 
amounted to. 39 • Fhe following reaction could be observed on

There was thus to be noticed a thermic reaction of i.3°C. Fur¬ 
thermore, the animal was dull, carried the head droopy, and 
had but little appetite. The tumefaction of the eye and the pe¬ 
riorbital region had become more marked. The animal coughed 
a great deal. All those symptoms caused us to consider the 
heifer tuberculous. 
About May 15 following she was slaughtered. In the eye 
tuberculous lesions had developed, but in only one bronchial 
ganglion I met with tubercles, which unfortunately were not 
subjected to a histologic or bacteriologic examination. 
Conclusions .—The results of those experiments show that it 
is difficult, but not impossible, to cause in the bovine species a 
generalized tuberculosis by means of pure cultures of the bacil¬ 
lus found in the human species. The identity of the two tuber-
