HUMAN TUBERCULOSIS IS TRANSMISSIBLE TO CATTLE.

so that the animal remained almost continually in a recumbent 
position. Notwithstanding this, the appetite remained such 
that the animal kept alive. 
On the 14th of May another tuberculine test was applied. 
The mean temperature on the three preceding days amounted 
to 39. 0 C. After the injection of 0.15 G. tuberculine, about 10 
o’clock at night, the following figures were obtained the next 
day :

This reaction of o.6° C. seemed to exclude the existence of 
tuberculous lesions. 
On May 27, about 6 weeks after the infection, the calf was 
slaughtered and found to be affected with a generalized tuber¬ 
culosis. The eyeball was markedly atrophied ; after hardening, 
the sections revealed tuberculous lesions, especially in the iris 
and which contained quantities of the Koch bacilli. The 
pharyngeal, cervical, mediastinal and bronchial lymphnodes on 
the corresponding side were tumefied and hypertrophic ; they 
showed on section miliary tubercles. From the bronchial nodes 
the bacillus has been cultivated and sections from the different 
ganglia revealed tubercular lesions, containing bacilli. 
The lungs were affected on both sides, especially at the 
apices. 
On the surface we found a few yellowish gray elevations, 
which, after incision, proved to be deposits of the size of a small 
nut, and containing a cheesy material. In coverglass prepara¬ 
tions from this material, bacilli were found, which, morpholog¬ 
ically, were similar enough to the Koch bacillus, but which de¬ 
colorized with the Ziehl-Gabbet method. 
The lungs enclosed furthermore numerous miliary tubercles, 
and a few grayish, fibrous ones of a greater size, of which the
