and small ; he has a good coat, he is gay, and his glance is 
clear. 
We designate the first by the letter A and the second by B. 
At 11:15 A is inoculated in the jugular with three cubic 
centimetres of a pure culture of pasteurella, found in the arth. 
ritis, received April 7. 
At 1 o’clock B (arrived a little later) is inoculated with 
10 cc. of the same culture. 
During the afternoon of April 16 nothing well marked was 
observed ; the temperature of both calves goes up a little, 
specially in B, which seems dull and breathes short ; but alto¬ 
gether the two animals seem to support the inoculation well. 
The 17th, at 8 a. m., the condition is changed. B has com¬ 
pletely recovered of its ill feelings; he is gay, and drinks with 
relish the milk offered to him; its temperature is normal 
( 3 8 ° 8 )‘ 
On the contrary, A seems very sick. It is stretched on its 
bed, in a mass of diarrhoeic matters, yellowish and foetid in odor ; 
eye is hollow ; flank corded ; abdomen retracted ; stands with 
difficulty when raised ; takes but a few mouthfuls of tepid 
milk ; its temperature is below normal (34°6). 
At 1 o’clock the condition of it is markedly worse ; he lies 
flat on the bed, scarcely breathing; at every instant he has 
spasms, with pitiful groans, followed by the expulsion of a small 
quantity of liquid, whitish, foaming matters ; we try to make 
him stand, but he falls back on the bed. 
At 5 o’clock he is dying ; the diarrhoeic discharges are 
mixed with blood ; respiration is stertorous ; temperature, 33 0 . 
At 5:45 p. M., he is dead. 
Immediate Post-mortem. —Extensive congestion of all the 
serous membranes (specially the omentum) and of all the vis- 
cerse, liver, spleen, kidneys, thymus, lungs. Slight effusion, 
clear and yellowish, in the peritoneum, pleura and pericardium. 
Ecchymosis or subserous petechia over the surface of the spleen, 
kidneys and heart, in and out. 
The mucous membrane of the abomasum is the seat of a
