In two other tuberculous cows the udders contained hard 
nodular tumovirs, and the milk was mixed with pus, but no 
tubercle bacilli were detected. Rabbits fed on the milk died 
from blood-poisoning, but no signs of tuberculous deposit were 
found after careful examination of the organs after death. So 
far as the inquiry has extended it appears to confirm what has 
hitherto been accepted — i.e. that only the products in which the 
tubercle organism is present are infective. The detection of the 
bacillus in milk becomes, therefore, a matter of great importancs.

But the process of preparation which is necessary to demon- 
strate the organism, although veiy easy to an expert, is beyond 
the grasp of the ordinary inspector of dairies, whose opinion on 
such a point would only mislead. 
Recent experiments at the College have proved that inocu- 
lation with the sputum of consumptive human beings induces 
well-marked tuberculosis in the calf The figure (5 A b) shows
