“ suspicious ” reaction. The cow was old and practically worth¬ 
less and so therefore condemned on the suspicious reaction to 
the temperature test. Our doubt about the accuracy of both 
reactions was increased for the reason that this cow had been 
in the herd for a number of years and none of the other animals 
had become affected, which is directly contrary to the general 
rule. She soon went to slaughter and showed a tuberculous 
lesion of the liver, thereby strengthening our faith in the intra- 
dermal test and explaining why the other cattle in the herd had 
not become affected. We then began the use of the intradermal 
test in small lots of cattle scattered out through the country 
around Independence, but never with the thought of condem¬ 
ning an animal showing a reaction to it until the temperature 
test had been applied. We soon found that the verification of 
the intradermal test with the temperature test was superfluous 
and unnecessary, but for the sake of trying the matter out 
thoroughly we continued to carry the temperature test along 
with the intradermal test in diseased herds after we began test¬ 
ing cattle in the vicinity of Columbia. However, we soon dis¬ 
covered the tuberculous centers in the vicinity of Columbia. 
We ventured to rely upon negative results from the intradermal 
test in all cattle with a good history. Before finishing the work 
around Columbia, however, we abandoned the temperature test 
and used the intradermal test altogether. We left the tuber¬ 
culin testing off about July i, and our whole force went on to 
tick eradication. When we took up tuberculin testing again last 
fall we did so with the intention of using nothing but the intra¬ 
dermal test. Several lots of cattle around Springfield, Pleasant 
Hill and St. Joseph were tested up to December 31, in all 3,458 
head. Forty-four herds were found to contain one or more 
reacting animals. One hundred and thirty-eight head of cattle 
were condemned. One hundred and three of these condemned 
cattle have, to this writing, been slaughtered and lesions of tuber¬ 
culosis visible to the naked eye found in all but two. Consider¬ 
ing the condemned animals alone, the intradermal test has ap¬ 
parently made two errors out of 103 post mortems. At this
