Washington. July 22-Another great advance
is recorded in the worldwide warfare against
the dreaded white plague. Pupils of Pasteur in
France including DR.. ROUx. are sure that Drs.
CaImette and Guerin. of the Pasteur Institute
of Lille. have finally discovered a vaccine which
will render humanity immune from the scOurge
CT tuberculosis This important announcement
is reported to the United States by Consul w. p.
AtwelI. from ROubaix. Or June 12 DR.. Albert
Calmette of Lille. read a paper before the Acad-
emy of Sciences in which embodied the re-
searches which he has made in company with
Dr. c. Guerin with regard to infection from
tuberculosis and it's remedy. The following is a
translation of their conclusions concerning this
most important matter:
Many experiments having demonstrated that
tuberculOus bacllli destroyed by heat or other
agents pass through the walls of the tnteStineS
readily as living bacili and found in the
meSentertc SangliOnS and lungs, we expert
mented with the object Of discovering whether
young animals-such as calves and kids, that

ordinary conditions. We are now convinced tnat

through the digestive organs
We shall publish before long detailed ac-
count Of these experiments as we'll as others in
progress for which we have used treated bacilli
from various sources and bovine baciln treated
by iodine and by hypOchlOrite of lime. Our be-
lief, founded on experiments, now Is that young
calves may be Vaccinated by simple intestinal
absorption of bacilli subjected 10 heat. and that
this method of vaccination is not dangerous. If
further experiments justify the application OF
this method as a preventive against bovine tu-
berculosis, nothing can be urged against its ap-
plicatiOn in the case of human beings.
We think IL will be possible 70 guard children
against natural infection by giving 70 them a
few days after birth and again few weeks later
a very small quantity OF tuberculOus bacilli Of
human and bovine origin subjected to heat and
mixed with little milk.
The only precautiOn absolutely necessary. and
one not always easy to apply. would be to guard
children thus vaccinated against all tuberculous
months Special nurseries might be founded for
new born infants of tubeFculous parents, where
they might be protected against all tuberculous
germs until they had acquired immunity through
vaccination. We believe that these difficulties
would be readily overcome in order to insure
rendering humanity refractory to tuberculosis
COntagfOn.
After DIR. Calmette had read his communica-
tion, Dr. Roux announced that ne and DR.. Villee
Of Alfort. had been engaged in similar expert
ments and that the results obtained by them CO.
incided remarkably with those OF Drs. Calmette
and CSuerin While DR.. Calmette'S experiments
are not yet quite conclusive. the matter is one Of
such interest to humanity that all investigation
in this line should be given publicity.
