EXPERIMENTAL PATHOLOGY.

d with portions of fresh lung, obtained from other rabbits 
hich had developed general tuberculosis, from their inoculation, 
few weeks previous, with tuberculosis matter in the anterior 
lamber of the eye. 
The pieces of lungs were cut into smaller fragments, and kept 
distilled water or a solution of chloride of sodium and then 
•ushed in a mortar. This crushed mass was filtered and the 
quid obtained, containing a certain number of bacilli, was mixed 
ith milk or water, which was given to the animals to drink. 
A single dose of from 3 to 8 cubic centimetres of the mixture 
ave rise after six or eight weeks to the development of typical 
iberculisations of the mucous membrane of the mesenteric 
lands and of the liver. The spleen, kidneys, mesentery, peri- 
>neum and pleura were in all cases found healthy. On the intes- 
nal mucous membrane, ulcerations sometimes appeared, resem- 
ling very much those found in the intestines of phthisis patients. 
In most of the animals there was a tliberalisation of the 
iib-maxillary and cervical glands, though there were no ulcera- 
ions either upon the buccal or the pharyngeal membranes. Once, 
single tubercular ulcer was found on one of the amygdals, with 
tubercular eruption upon the tongue. Altogether these expeii- 
aents give another proof of the transmissibility of tuberculosis 
hrough the food, and again they confirm those of Falk, upon 
he resistance which the bacillis of tuberculosis offers to digestive 
ecretious. 
Like Falk, Fisher has observed that where alimentary masses, 
nfected with the Koch bacilli, have been previously exposed to 
mtrefaction, the virulent activity is diminished if not destioyed. 
Fisher also remarks that, in his experiments, he has always 
used young tubercles, free from spores, but containing tubercular 
! bacilli only, and therefore that he cannot agree with Wesener, 
who says'that in the digestive canal, the spores alone preserve 
cheir virulent activity, while the bacilli have none. He also ob¬ 
jects to the theory that normal gastric juice destroys the bacilli 
of tuberculosis. 
And again, from the fact that Wesener has produced tuber¬ 
culosis in animals injected with the sputa of phthisis in the
