340 GENERAL REPORT OF THE SCIENTIFIC COMMISSION. 
tice. It has confined itself here to the ascertainment of the 
amounts resulting«from particular experiments. 
From a summing up of these experiments, we find that 45 
animals out of 100 have contracted peripneumonia through 
cohabitation, and that 24 have experienced slight indis- 
position : to resume, 65 have felt the influence of con- 
tagion in slight degrees, and 32 have shown themselves 
refractory to it. 
The proportion of animals who have recovered every 
appearance externally of health, after having experienced the 
disease, has been at the rate of 83 out of 100 sick, and that 
of those who have died, of 17 per cent. 
Experiments on Inoculation for Peripneumonia. 
The questions the committee proposed to resolve under 
this head were the following : — 
1. Is peripneumonia capable of being communicated to 
animals in health by inoculation with the blood, the saliva, 
matter flowing from the nose, and excrementitious matter 
coming from animals so affected? 
2. Have animals who have been submitted to inoculation 
in one or other of these ways, contracted, through the 
inoculation, an immunity to a certain degree from the 
disease ? 
3. In cases where inoculation with the liquid fails to 
produce on animals an exact counter-action of the form and 
symptoms of the inoculated disease, as that is remarked in 
inoculation for every contagious disease, what are the local 
and general phenomena found to arise from it? In what 
proportion and intensity do such phenomena present them- 
selves? What proportion of animals succumb from in- 
oculation ? How many recover their health after having 
been submitted to such tests, and in what sort of condition ? 
4. Such animals of the bovine kind as have experienced 
inoculation with pulmonary fluid, do they, through this trial, 
acquire any privilege of resisting the contagion of peri- 
pneumonia? 
The experiments to resolve the question of contagion 
accruing from inoculation for peripneumonia with the blood, 
the saliva, nasal discharge, &c., having been performed but 
on six animals, the committee have not thought they were 
numerous enough to serve as a basis to rest any conclusion 
upon ; and on this account have not taken them into calcula- 
tion, but for memoranda. At the same time, the committee
