342 GENERAL REPORT OF THE SCIENTIFIC COMMISSION 
From the results of these experiments on inoculation for 
peripneumonia, the committee have deduced the following 
conclusions : — 
1. Inoculation with the liquid extracted from the lungs of 
the bovine beast labouring under peripneumonia, does not 
convey to animals in health of the same species any similar 
disease, at least in its seat, to that from which the in- 
oculating fluid was taken. 
2. The appreciable phenomena, consecutive on inoculation, 
are those of a local inflammation, light and confined to the 
place of inoculation, in a certain number of inoculated sub- 
jects; grave and diffuse, accompanied with a general reaction, 
proportioned to the intensity of the local action, and com- 
plicated with gangrenous befalments, in others of the in- 
oculated subjects, so as to terminate by death in certain of 
these last. [In the experiments made by the committee, 
inoculation has proved benignant in its effects in 61 out of a 
100 of the inoculated subjects, grave and complicated with 
gangrenous accidents in 38, mortal in 1 1 ; 88 subjects out of 
a 100 have consequently recovered their health after in- 
oculation — 6l without presenting any apparent traces of the 
operation they had undergone, and 27 with exterior local 
lesions, more or less extensive and marked, according to the 
intensity of the gangrenous affections to which inoculation 
had given birth.] 
3. Inoculation with the fluid taken from the lungs of ani- 
mals suffering under peripneumonia possesses a preservative 
virtue — it invests the organism of the greatest number of 
animals on whom it is practised with an immunity which 
protects them against the contagion of the disease for a 
period of time remaining to be determined, but which the 
experiments detailed above have not set at less than six 
months. 
If, now, in order to appreciate the economical value of 
inoculation, of which direct experiment shows the preserva- 
tive properties, we wish to compare the results which the 
practice of it has given in the different essays reported, 
with those which have been furnished by all the experiments 
on cohabitation related, here are the conclusions to which 
this approximation -leads us: — 
From a statistical estimate of these experiments, as made by 
the committee, it results on the one part that, out of 100 
animals of the bovine species exposed to the influence of 
contagion through cohabitation, S2*6l are saved, and 21*73 
only experience transitive indisposition, of little import to 
the general health, though considerable in the favorable
