REVIEW OF BIOLOGY. 
363 
days 200 grammes of faeces were gathered and diluted in ioo 
cubic centimeters of water. The product of this, filtrated, fur¬ 
nished, after 12 hours, several cubic centimeters of a greenish 
liquid of which 2 c. c. were injected in the ear of a rabbit. Six¬ 
teen of these animals were thus inoculated. Two died of septi¬ 
caemia, one of intoxication, thirteen became tuberculous. Two 
died after a month and had pulmonary miliary tuberculosis. 
The eleven surviving ones were killed afterwards and presented 
tuberculous indurations of the lungs, liver, spleen and kidneys. 
Besides these experiments, the microscopic examinations of the 
faeces of the bull revealed the presence of the bacilli of Koch. 
This demonstrates evidently that faecal matters are virulent 
and liable to propagate tuberculosis as much as sputa of men.—

Inoculability of Tuberculosis of Mammalia to Birds 
[by MM. Cadiot , Gilbert and Roger ].—111 previous papers the 
authors have tried to show the difference between the tuberculosis 
of mammalia and that of birds. They have demonstrated that 
inoculations of the human bacillus does not produce lesions in 
gallinaceous. There are exceptions to this rule, however ; out 
of 40 hens inoculated with human bacillar lesions, 5 presented 
visceral tuberculous granulations. Since 46 hens were inocula¬ 
ted ; 12 of them were placed in conditions which show that the 
hyperthermy of the birds is not the principal cause of their resis¬ 
tance to the tuberculosis of mammalia. Of 34 others, 3 took 
tuberculosis. Altogether out of 86 hens, 7 took tuberculosis and 
transmitted it to 2 other hens. These positive results, representing 
10 per cent., are unfortunately left without explanation, the cause 
of resistance of the birds and the conditions of their receptivity 
remained unfound. But the experiments of the authors allow us 
to recognize the modifications that the bacilli of mammalia 
may undergo in the organism of gallinaceous. Sometimes it 
preserves its original character and cannot be transmitted to the 
hen ; at others it becomes able to be reinoculated, conserving 
sometimes, from its origin, the possibility to resume it in animals, 
which, like the dog, are little sensible to the aviary virus. 
Bacilli of mammalia and of birds do not then represent different 
breeds of a same species; their distinctive characters are too 
contingent to establish between them an absolute distinction.—
