Healthy. 
A number of fairly large broken-down tuberculous nodules in right 
tracheal gland ; multiple tubercles in one mediastinal gland. 
Multiple tuberculous foci (small) in left bronchial gland and in upper 
mediastinal gland; a single small tubercle in right caudal lobe ; a flat 
suspicious-looking nodule on external muscular surface of the abdomen. 
Healthy. 
Abscess in liver ; non-tuberculous.

Abscess the size of a hen’s egg-.attached to the caudal lobe of the right 
lung and to the diaphragm; non-tuberculous. 
Healthy. • 
Healthy, 
Multiple abscesses in liver; non-tuberculous. 
Minute tubercles in both mediastinal glands; a small one in the right 
caudal lobe. 
A single calcified pin-head nodule in one left bronchial gland. 
Healthy. 
Posterior mediastinal gland contained one minute nodule, no other 
lesions. (Reserved by Dr. Smith for microscopic examination ; since 
reported upon by him as non-tuberculous.) 
Several minute tubercles in left mediastinal and bronchial glands. 
Healthy. 
Several minute tubercles in posterior mediastinal glands. 
Of these 20 animals that had been tested with tuberculin and not condemned, there 
appear to be 6 that show signs of infection at the post-mortem examination. It is unfortu¬ 
nate that they were not all re-tested just before the slaughtering, for it is quite open to 
question whether in some of them the infection did not occur o/ter the first injection of 
tuberculin. In none of them was there any extensive infection. 
Sluninary. 
One hundred and thirty animals tested with tuberculin and 
killed in the presence of experts called by the special joint com¬ 
mittee of the Legislature. I was present, and examined 90 of 
these. One (No. 10) should be omitted, for the reason that it 
did not react and was not condemned, having been sent with the 
others by accident. This leaves 89 that I saw and examined in 
person. Of these. No. 91 presented no gross lesions, and there 
has not been sufficient time to complete a microscopic examina¬ 
tion ; No. 122 reacted to the test so slightly that the animal 
should not have been condemned ; and the tubercle reserved for 
microscopic examination from No. 121 has not yet been satis¬ 
factorily studied. The 30 animals that I did not see and exam¬ 
ine all presented satisfactory evidence of tuberculous infection,
