A paper by DIR. Jaime Ferran on pro

hypodermic injections of pure cultiva.
tioDs of the comma bacillus was read
before the Academy of Sciences, Paris,
On July 10. The author describes the
results obtained by his method as most
amazing, and he maintained that his
system offers an absolute remedy against
Tue disease. The dangers OF attack an
death begin to disappear five days after
vaccination, and the immunity from
further attack increases with each sue
csssive injection. The period of immu

minimum OF wo months may already be

fell still further when the pressure on
