EXTRACTS FROM FOREIGN JOURNALS. 
was given a portion of the lungs and ganglions from No. 1, and 
was killed after twenty-three days. There was nothing apparent 
on the surface of the organs, but the maxillary ganglions were 
hypertrophied, and under the microscope exhibited tubercular 
granulations in their first period of formation. 
No. 6. On the 18th of December, tubercular ganglion was 
taken from No. 1, and a portion of it cut off and crushed and 
filtered through cloth. One cubic centimeter of this solution was 
injected into the left side of the soft palate. Fifty-seven days 
later, the left maxillary ganglion was enormous, while that of the 
opposite side was scarcely tuberculous. All the organs were full 
of tubercular granulations, some of which were white on the 
centre. 
Third Series. —No. 7. On the 11th of January, 1880, the 
remains of No. 2, which died the day before, were given to a 
young pig. On the 10th of February the maxillary ganglions 
had become voluminous. On the 26th of March the animal was 
in extremis. When killed, it was found in the last period of gen¬ 
eralized tuberculization. The soft palate was tuberculous. 
No. 8. On the 11th of January, 1880, a pig two months old 
was subjected to experiment. Some of the blood from No. 2 
was- injected under the skin. It was followed by an irregular, 
hard and tuberculated tumor. Sixty-one days after, it was killed, 
and tubercles were found on the skin and the ganglions, and nu¬ 
merous gray granulations on the pleura, the lungs, liver, spleen 
and omentum. 
To resume, these experiments show that the lesions of the pig 
belong to acute tuberculosis, and that they prove fatal in a short 
time, usually a few weeks. Tuberculosis of the pig is analogous 
to hasty consumption in man. The bovine family, on the con¬ 
trary, is subject to chronic tuberculosis. From this, it results 
that young pigs, coming from tuberculous parents, offer but little 
resistance to the disease and die young; and that in adults which 
become tuberculous, the rapid march of the disease prevents 
reproduction. 
In the point of view of contagion, these facts prove also that 
tuberculosis is easily transmitted, 1st, by the injection of tubercu-
