MONSTROSITIES. 
217 
cubic centimeters in a closet where eight rabbits, ten guinea-pigs, 
four rats and four mice were placed. After from fourteen to 
twenty-five days seven of the animals had died, and the others 
were killed after twenty-eight days. The lungs of the pigs and 
rabbits were filled with tubercles like those produced by the in¬ 
halation of dried tuberculous sputa, extending into the pul¬ 
monary alveolae, as in spontaneous tuberculosis, which once more 
proves that this is truly a tuberculosis by inhalation. 
Amongst the rats and rabbits the lesion was not as caseous as 
in the other animals. 
In all cases the tubercles artificially obtained, reinoculated to 
other animals, never failed to produce general tuberculosis. 
II. — Resume. —Thus all the processes of bacillar infection, 
inhalation, inoculation, produce the same result as the inoculation 
of the tuberculous substance. They give rise to miliary and to 
caseous tubercles, equally with spontaneous tuberculosis, and 
there is not even an exception for refractory animals, as dogs, 
(aits, etc. Two hundred and seven experiments of Koch prove 
this general law, viz : bacillemia is equivalent to tuberculosis. 
It may be objected that other parasites may produce similar 
effects, viz; a tuberculosis; but it must be observed that every¬ 
where and always, in true tuberculosis, whatever its origin may 
be, the bacillus is always found, and never in the pseudo-tuber¬ 
cles. It can then be said that the tuberculous bacillus is in the 
same corresqjondence to tuberculosis as the carbuncular bacteria 
is to anthrax.
