Dr. Rosenbergers Method Of Discovering
The Germ.

Philadelphia, Feb. Here for the
first time are the complete and authen.
tic details OF DIR. Randle G. Rosenber.
gers tuberculosis discovery The de-
tails are given as they are published
today in the American journal of the
Medical Sciences. Professional ethics
has prevented DIR. Rosenberber from
making the disclosure prior to that Of.
fcial publication. The value Of DR.,
Roseu6ergtfs discovery lies in the
fact that II enables any physician to
discover tuberculosis germs in the
blood al their very hrst appearance,
long before they have manifested their
presence in the lungs and long before
tho disease has reached what Il now
called the incurable stage. The number
OF tuberculosis victims that can be
saved from the grave by this discovery
Is inealculable.
DIR. Rosenharger, who Is the bacteri-
ologist of both the jefferson Medical
college and the Philadelphia hospital,
established the accuracy Of his discov-
cry by testing the blood Of threescore
patients in the following manner
A tourniquet is bound tightly about
the patients arm to bring the veins
into prominence. From any vein Of
sufficient size at the elbow the blood
Is drawn with hypodermic syringe,
after the skin at the spot selected has
been first sterilized 10 insure the re.
moval OF every possible means Of in
lection or contamination from the skin
itself.
About two teaspoonfuls Of blood are
drawn from the vein and the needle
prick Is dressed and bandaged. there be.
ing no resultant pain or trouble beyond
a slight itching for few moments.
The blood withdrawn is Immediately
mixed with salt solution to prevent
its CLOTHING and the tube containing II
is placed on ice for twenty four hours.
Herein lies the radical difference be.
tween the cultivation or growing Of
the typhoid germ in what are known
as culture mediums wherein heat
plays part The normal salt solution
in which blood suspected of containing
tuberculosis germs is placed, must
clcnrly conforms to the elements of the
blood itself, and in addition there is
introduced about 2 per cent Of citrate
OF soda.
After twenty four hours the blood
has settled in the vial and this sediment
which has gone 60 the bottom Of the
glass. is withdrawn, siphon like, through
a hollow glass tube. Being spread up
on small glass slides this blood is dried
on small strip Of metal held firmly
IN place above a small, even gas fame.
thoroughly dry, it Is almost indistrne-
tible except through breaking Of the
glass slide, itself
These slides are next immersed in
distilled water and the red corpuscles
are removed by this means. The slide
Is again dried. II ID next stained"

Is stained red; immersed again for five
minutes in what is known as Happen

stained blue with the exception Of the

red. Therein is the entire Rosenber
