absolutely secured from infection, whatever be the mode 
of inoculation, and the intensity of the virus. All the 
other test dogs which were inoculated at the same 
time died of rabies. In 1884, Pasteur found the means 
of attenuating the virus. For this purpose he has 
inoculated a morsel of the brain of a mad dog into a 
rabbit’s brain, and has passed the virus proceeding 
from the rabbit through the organism of a monkey, 
whence it becomes attenuated and a protective vaccine 
for dogs. This is the first step towards the extinction 
of this terrible disease. 
VII. GLANDERS. 
This, again, is a disease easily transmitted from 
horses to man. Glanders, or farcy, is caused by the 
presence of a bacterium, observed as early as 1868 
by Christot and Kiener, and more recently studied at 
Berlin by Schiitz and Lofler. This microbe appears 
in the form of very fine rods (bacillus) in the lungs, 
liver, spleen, and nasal cavity. Babés and Havas 
found this bacillus in the human subject in 1881. 
Experimental cultures have been made simultaneously 
in France and Germany, and have given identical 
results. 
Bouchard, Capitan, and Charrin made their cultures 
in neutralized solutions of extract of meat, maintained 
at a temperature of 37°. By means of successive 
sowings, they have obtained the production of un-
