^ETIOLOGY OF TUBERCULOSIS.

8. Phthisic lung with vomicce , intestinal abscesses and caseous mesentric 
glands. —With the contents of one vomica, which contained quite a number of 
bacilli, two guinea pigs were inoculated, and four with the very bacilli-ricli sub¬ 
stance of the mesentric glands. The last died in the course of the fifth and sixth 
weeks, of the first two one died in the sixth week, the other was killed a few days 
later. All tuberculous. 
9. Gaseous bronchitis and intestinal tuberculosis. —With the moderately 
bacilli-rich lung substance, five guinea pigs were inoculated. Two of them died 
in the eighth week ; the others were killed before the end of the same week. 
All tuberculous. 
10. A'phthisic lung containing vomiccc. —With thickened lung tissue which 
contained a few bacilli, four guinea pigs were inoculated. Of these, three died 
in the seventh and eighth weeks, the last not until the twelfth week. All tuber¬ 
culous. 
11. Phthisic sputum. More or less bacilli-rich sputum freshly taken from 
three different sufferers from phthisis was inoculated at different times into nine 
guinea pigs. The animals died, part before the eighth week, the others were 
then killed. They were all tuberculous. 
12. Phthisic sputum dried for two weeks :—Three guinea pigs. Two died in 
sixth week, third was then killed. All tuberculous. 
13. Phthisic sputum dried for two months. —Three guinea pigs. Killed 
after five weeks and found with tuberculosis in lungs, liver and spleen. 
14. Tuberculosis of the uterus and “ tubenP— Caseous substance from the 
tuben inoculated into six guinea pigs. Two animals died after seven weeks. 
The others were killed in nine weeks. All tuberculous. 
15. Pus from a tuberculous abscess of the kidneys. —Two guinea pigs were 
sub-cutaneously inoculated with it, and two suffered an injection into the cavity 
of the belly. The animals were killed after five weeks. In the guinea pigs sub¬ 
cutaneously inoculated, the inguinal glands were swollen and beginning to be 
caseous ; in the enlarged spleen were numerous, in the lungs few,little grey knots. 
The injected guinea pigs had many tuberculous knots on the peritoneum and in 
the omentum ; spleen more strongly tuberculous than in the inoculated animals, 
a’so larger and more numerous tubercles in the lungs. 
16. — Pus from a congestion-abscess occasioned by aortex-caries. —Five guinea 
pigs received from it an injection into the belly cavity. The same boiled distilled 
water which served for thinning the pus was injected into the belly cavity of one 
guinea pig which served as control-thier (animal to prove whether association 
with infected animals would give the disease). This animal was left in the same 
cage with the others. The animals were killed in the seventh week. The “con¬ 
trol-thier ” had not a trace of tuberculosis either in the belly cavity or in the 
lungs. The animals into which the pus was injected showed a remarkably fine 
tuberculosis of the peritoneum and of the omentum, besides this also a more or 
less advanced tuberculosis of the spleen and lung. 
17. — Fungous elbow -joint —Substance with very few bacilli inoculated into 
four guinea pigs. Killed in the tenth week. All tuberculous. 
18. — Scrofulous glands from three different cases inoculated into ten guinea 
pigs at different times. The inoculating substance contained few bacilli and cor-
