gans, where they are carried by the circulation. They are very 
easily found in the lungs and spleen, when death follows rapidly 
in transfusions of carbunculous blood; like those of the clots of 
the heart, they yet possess their vitality and may be inoculated 
with success. 
3d. When the animal survives more than three days after 
the transfusion, bacteridies disappear from the lungs and spleen, 
as they have from the blood, and the subject recovers. 
4th. Then, not only there is no proliferation of bacteridies in 
those parts of election, splenic, pulp and blood, but the bacteridies 
introduced by the thousand millions in those are soon destroyed 
after passing probably through a series of periods of infectious 
activity, gradually decreasing. 
5th. The inaptitude of the organism to the continuation of 
life of bacteridies, is not however complete: one region at least 
makes exception, this is the surface of the encephalon. Bacteridies 
carried and gathered in the meshes of the pia-mater may survive 
there and grow and produce a mortal inflammation. But the 
growth takes place with peculiar characters; elongations and in¬ 
flexions of the clusters, apparition of spores; characters which 
look somewhat like the proliferations of bacteridies in artificial 
cultures or after death , under certain conditions of heat and of 
medium, in the organs and the blood of subjects which succumb 
to the true sang de rate. Those characters are never seen during 
life on those last animals; the multiplication takes place by scis¬ 
sion in short clusters. 
6th. The infectious activity of these bacteridies of the pia- 
mater is very great and contrasts with the sterility of the blood 
of the other parts of the body. Nevertheless, from what has been 
said previously, one cannot consider as absolutely perfect, this 
peculiar local activity preserved in an organism enjoying a gen¬ 
eral immunity. 
A CASE OF THE LONGEST INCUBATION OF HYDROPHOBIA IN MAN. 
Mr. Leon Colin reported to the Academic de Medicine, of 
Baris, a case of human hydrophobia with an unusually long incu-
