One cow, with injections of the serum of vaccinated rab¬ 
bit, immunized rabbits against an injection of virulent pneu¬ 
moenteritis. This result confirms that of Mr. Metchnikoff. 
C. Comparative experiments of Serotherapy. —It was inter¬ 
esting to know if the serum of rabbits vaccinated against 
swine plague would grant a certain degree of immunity against 
the virus of hog cholera and of pneumoenteritis. The follow¬ 
ing are experiments made in that direction. 
No. 325.—30-VI, injection of 5 cc. of the serum of rabbit No. 107, vaccinated 
and tested against swine plague. 31-V, after 24 hours, injection of cc. of virulent 
blood of hog cholera, d he witness dies in 18 hours. The 1—VI, great hypersemia 5 
the 2—VI, the rabbit shows a temperature of 42° at 8 a.m ; the ear is drooping j 
second injection of serum at 6 p.m.; death at 7.30. The rabbit inoculated with the 
preventive serum resisted 30 hours longer than the fresh rabbit. 
No. 307. ik-440. Injection of fee. of the serum of rabbit No. 107, vaccinated 
against swine plague; testing inoculation of hog cholera after 5 hours. The rabbit 
has a large oedema, and dies 21 hours after the injection of the virus ; the witness, 
which weighed ik-715, dies 5 hours earlier. Here again, the action was evident, 
but the rabbit was too young. 
No. 324.—30-V ; injection of 4 cc. of the serum of rabbit No. 107, vaccinated 
against swine plague. 3 I— V, after 24 hours, injections of cc. of virulent blood of

I_VI > 9-30 a.m., 41 0 6; ear tumefied. 2-VI, 8.30 a.m., 40°5, injection of 2

jection of £ cc. of serum, and the 5-VI, last injection of 1 cc. The rabbit had in 
all 9 cc. of serum. He had been tested and treated with rabbit No. 326, which was 
protected with 8 cc. of the serum from the rabbit vaccinated against pneumoenteritis. 
Guinea-pig No. 6. I 7 ~VII. Subcutaneons injection of 2 cc. of the serum
