fed on raw meat were affected with general tuberculosis. 
Tuberculous organs boiled for thirty minutes, and some specimens 
which were made into sausages and fried in the ordinary way, pro- 
duced tubercle. But specimens of tuberculous lungs and liver

boiling for fifteen minutes, proved to be harmless to a number of 
guinea-pigs which were fed on them. 
Experiments with Koch’s Tuberculine. 
Koch’s fluid (tuberculine) was tested on cattle, horses, and swine 
for the purpose of ascertaining its value as a means of detecting 
tubercle ; the experiments did not, however, lead to any satisfactory 
result, as animals which, on post-mortem examination, were found to 
be free from tubercle, suffered a reaction as decided after injection 
as those in which advanced tubercle was detected after death.
