cool place until complete separation of the clots and the 
serum drawn with the pipette. I will relate some of my ex¬ 
periments : 
No. 299.—Receives 5 cc. of serum from rabbit No. 101 in the vein of the ear. 
Test after 18 hours ; the rabbit dies in the night of the eighth day. At post mortem 
are found, besides the very marked oedema of the ear, a small spleen, high conges¬ 
tion with small suppurative centers through both lungs. Culture of the blood gives 
a pure result. The witness receives 5 cc. of serum of a fresh rabbit, he dies about 
22 hours after the testing injection, without other lesions than a small abscess at the 
point of inoculation. He lives about seven days longer. 
No. 246.—Injection of 4.5 cc. of the serum of rabbit No. 198. Test 30 hours 
with g-g- cc. of culture of swineplagtie in bouillon. Large oedema of the ear with 
abscess which ulcerates spontaneously. Dead in five days. Post mortem shows 
that the abscess has extended under the skin of the head; the spleen is enlarged, 
few microbes in the blood. The witness dies in 20 hours after four days longer life. 
No. 247.—Injection of 3 cc. of the serum of rabbit No. 178. Tested after 25 
hours. Dead in five and one-half days. (Edema is very large, and abscess extends 
under the skin as far as in front of the sternum. The witness dies in 20 hours after 
four and a half days longer life. 
No. 280.—Three injections of altogether 11.55 cc. of the serum of rabbit No. 
198, the third injection of 6 cc. is made eight days after the first two. The test is 
applied two days after the last inoculation ; the witness dies in less than 12 hours, a 
rabbit not well vaccinated in 30 hours. Our rabbit has at the point of injection a 
slight hyperaemia which disappears after four days. A second test, made twelve 
days after the first, kills the rabbit in about 30 hours. 
No. 253. Two injections, made 5 minutes apart, one intravenous of 4.5 cc., 
the other subcutaneous of 3 cc. of the serum of rabbit No. 198 ; test after 2 hours. 
A second labbit submitted to the same experiment after having received another 
serum dies about seven days after. The rabbit showing no morbid symptoms, re¬ 
ceives five days after the first testing inoculation ^ cc. of virulent culture of swine 
plague , and dies in the night of the seventh day. 
No. 276.—Subcutaneous injection of n cc. of the blood of a dog vaccinated 
against swine plague. Test after about 19 hours. The next day, temperature 41 0 , 
large tumefaction of the ear, intense diarrhoea, death in 51 hours. The witness dies 
in less than 18 hours. Longer length of life one and a half days. 
No. 252.—Subcutaneous injection of 10 cc. of the blood of a dog vaccinated 
against swine plague; the next day another injection of 6 cc. of the same blood. 
Test after several hours ; the oedema of the ear, very large on the second day of the 
testing examination, diminishes and reincreases again towards the sixth day ; the 
rabbit dies in seven and a half days. Marked postponement of death. Small 
quantities of the blood of this vaccinated blood retarded the death but only a few 
hours. 
No. 291.—Two subcutaneous injections of 6.5 cc. and 3.5 cc. of the blood of 
dog vaccinated against swine plague , and made twenty-three days apart. Test the 
fifth day after the second injection ; the rabbit dies about in the same time as the 
witness, in 12 to 16 hours.
