turnip, or some similar body in the oesophagus between a

Tuberculin as a diagnostic agent was not extensively used, 
two herds only having been tested with it, one in Westches¬ 
ter County in March, on the herd where all the animals were 
killed; the other near Poughkeepsie, Dutchess County, in 
May, the animals being killed early in June. In both herds 
the results were quite satisfactory, but the latter one was 
much the better to use for the experiment, as it contained a 
few healthy creatures, and their general condition was better 
than in the first instance when it was tried. The Poughkeep¬ 
sie herd consisted of two bulls and thirty-one cows and heif¬ 
ers, which were tested with tuberculin, besides which there 
were three yearling heifers which were not inoculated, and 
two young calves. Of the thirty-three animals, all but four 
cows reacted to the tuberculin, and one was unsatisfactory, 
as she was not well, and had a temperature of io6 Q at the 
time of the inoculation. Hence twenty-eight animals out of 
thirty-three may be looked upon as tuberculous according to 
tuberculin. A physical examination of this herd indicates 
one cow with general tuberculosis, one cow and two heifers 
(one of them a yearling not tested with tuberculin), “ roarers,” 
from enlarged tuberculous glands back of the pharynx, and 
three cows suspicious, because of their coughing and having 
a bad history connected with the farm. 
All the animals that reacted to the tuberculin were killed 
(and also the heifer that was a roarer, but not tested), and 
found in every instance to be more or less tuberculous. One 
cow that did not react was killed and found to be perfectly 
healthy. 
The question in this trial seems to be : Is tuberculin too 
fine a diagnostic agent for use in the examination of dairy 
herds, unless used as an assistance to our other powers of 
observation ? 
One cow had only three small nodules in the liver, another 
a small cheesy posterior-pharnygeal gland, two or three others 
tuberculous posterior mediastinal glands. Now, the question 
is : Are such animals any danger to other cattle or to the
