which he called pneumo-enteritis of swine. But he was entirely 
' in error as to the nature and the properties of the parasite. As 
the microbe of cholera, he described a bacillus with spores larger 
than the bacteridie of anthrax. Very different from the true 
microbe of hog cholera, the bacillus of Dr. Klein has no relation 
with the etiology of the disease. 
4. —After assuring ourselves, by direct experiments, that the 
disease does not recidivate, we have succeeded in inoculating it 
under a benign form, and then the animal becomes refractory to 
the deadly disease. 
5. —Though we believe new experiments are still necessary to 
confirm our results, we are at present convinced that, from next 
spring, the vaccination of the attenuated, virulent microbe of 
hog cholera will become the great safeguard of hog-breeding 
establishments .—Gazette Medicate. 
UPON RABIES. 
By M. Pasteur. 
Mr. H. Bouley presented at the Academy of Medicine, in the 
name of the author, the result of his numerous investigations 
upon rabies. The conclusions are as follows: 
1. —Dumb and raving rabies, more generally, all kinds of 
rabies, proceed from a common virus. 
2. —Nothing varies more than the rabid symptoms; each case 
has, so to speak, its own, and it is almost certain that their char¬ 
acters depend upon the nature of the parts of the nervous sys¬ 
tem, encephalon or spinal marrow, where the virus is localized 
and developed. 
3. —In the rabid saliva, the virus being associated with various 
microbes, the inoculation of that saliva may give rise to three 
kinds of death—by the microbe of the saliva, by the exagger¬ 
ated development of the suppuration, by hydrophobia. 
4. —The rachidian bulb of a person who has died with rabies, 
like that of any animal in the same condition, is always virulent. 
5. —The rabid virus is found not only in the rachidian bulb, 
but also in all or some parts of- the encephalon. It is also local¬ 
ized in the marrow, and often in every part of that organ.
