CONTRIBUTION TO THE STUDY OF SWINE PLAGUE, ETC. 427 
the ear; large abscess, and death in the night of the 6th of March. At post mor¬ 
tem, on same side of injected ear, purulent pleurisy, and purulent collections in the 
left lung. The sowing from the blood and from one of the abscesses gives pure 
| cultures of szvine plague. 
I wish to remark that most of the animals have presented 
during the duration of the vaccination and after the test in¬ 
jection a noticeable increase in their initial weight, which 
proves that the toxine has no'bad, lasting effect on the 
organism. 
The experiments of vaccination with the serum will be 
considered further on. 
As to hog cholera , the results of the vaccinations are far 
from being as brilliant; this is specially due to the fact that 
at the beginning the virulency of the microbe was much less 
active, and, besides, uncertain, as well as to its toxicity. Later 
on the results were better. 
No. 132.—Weight the 10-I, ik-910; five injections of blood and cultures steril¬ 
ized by heat (5^ cc. of blood and 6 cc. of cultures) ; the rabbit resists the i-II to a 
first test, which kills the witness, but he dies after a second injection of virus the 
23-II in less than 24 hours. Pure cultures of hog cholera. 
No. 139.—Weight the 21-XI, 2ks-i6o ; four injections, altogether 8 cc. of steril¬ 
ized culture; tested the 19-II, the rabbit, which weighed 2ks-240, dies in less than 
16 hours. The blood gives pure culture. 
No. 146.—Weight the 30-XI, ik-640 ; after seven injections of sterilized cult¬ 
ure, altogether 18 cc., the rabbit dies the 31-III, in less than 24 hours after the in¬ 
jection of test. 
No. 173.—Weight the 6 - 1 , ik-750; receives 19 cc. of sterilized culture in seven 
injections, and weighs 2k-37o the 31-V, date of the trial. The witness dies in 18 
hours, while the subject vaccinated lasts about 60 hours. Pure cultures. 
No. 178.—Weight the 13-I, ik-600; seven injections, altogether 34 cc. of steril¬ 
ized cultures, some by heat, others by filtration with Pasteur bougie ; test the 27-III, 
weight ik-990; the witness dies in 48 hours; the rabbit treated during nine days, 
i-IV ; he then survived more than seven days. At the post mortem were found, an 
abscess which had given rise to a large tumefaction of the ear and of the neck, right 
purulent pleurisy, small superficial abscesses in both lungs, left lung extensively 
hepatized ; cultures with the pus and blood are positive, though these last were weak. 
No. 260.—Weight the 3-IV, ik-860; six injections, altogether 8 cc. blood ster¬ 
ilized at 6o° ; first test, the 12-VI, weight 2ks-43o ; the witness dies in 24 hours, 
the subject treated continues to do well; a second injection of hog cholera culture is 
well supported the 19-VII. 
No. 311.—Weight the 18-V, ik-680; four injections, in all 7^ cc. of diluted 
blood sterilized by long contact with thymic acid; test injection the 22-VI, weight 
ik-900 ; no noticeable effects. The witness dies in less than 18 hours.
