tubercles, which are yellow, hard, but not softened or caleified. 
The viscera of the abdominal cavity and glands are normal. 
Cow No. 6 (killed June ioth).—The mouth, the velum of the 
palate, the pharynx, the larynx and the trachea do not present 
any noticeable lesion. The pharyngeal glands are rather large 
and granular on cutting (histological examination has shown 
them to be sound). 
Both lungs are filled with fine miliary granulations, most of 
them being translucent, a few being opaque about the centre. 
All have developed under the pleura or on the periphery of the 
lobules; there is no trace of congestion or inflammation of 
the pulmonary tissue in their immediate vicinity. The bronchia 
being incised their whole length show the mucous membrane 
to be intact. The bronchial glands are hypertrophied, dis¬ 
tended with a serosity, but free from all noticeable lesions, but 
the posterior mediastinal glands are almost all affected, but in 
different degrees ; one has increased its volume ten-fold ; its 
cortical layer literally filled with very fine nodules, which are 
still translucent, being at the first stage of evolution. 
The viscera of the abdominal cavity and their ganglions 
are normal. 
THIRD DOT, COWS 7 AND 8—INHADATION OF TUBERCUDOUS 
EMULSION. 
May 21, Cow No. 7 gives a slight reaction, 39.5, but the re¬ 
action was not marked until the 27th, when at 5.30 A. M. 39.7? 
8.30 A. m. 39.4, 11. 3° a. m. 39.3, 2.30 p . m. 39.4. The 2d of 
June the reaction is hardly noticeable, immunity becoming al¬

In this particular case the period of incubation has been 
from 13 to 19 days. As to Cow No. 8 she did not react until 
the 27th of May, that is on the 19th day, when the tempera¬
