PARIS, January IAN announce
ment which declares they have dis
covered serum that both prevents and
cures yellow fever has been made to
the Academy of Medicine by two ply
sicians of the Pasteur Institute.
The discoverers are Prof. Auguste
Petit and DR.. Georges Stefanopou.o, a
Greek physician.
Petit summed up the results of his
experiments in four points. He said the
serum has no unfavorable effect, it neu-
tralizeS in test tubes the virus OF yellow
fever. it protects the Asiatic monkey
MacacuS Rhesus-very susceptible to
yellow fever-againSt the disease, ana
it prevents yellow fever from declaring
itself in this monkey from one to three
days after injection of virus.
Experimental on Monkeys.
The physicians took these expert
mentS on monkeys as conclusive, since
yellow fever in the monkey not only re-
sembleS that malady in man, but Is still
more severe. Nearly all monkeys In
oculated die, but the mortality for hu-
man beings in Africa is around 70 per
cent.
Six hundred phials of the new serum
have been sent to the governor general
of French West Africa. These are Suffi-
cient for the treatment of 20 victims OF
yellow fever. An equal number OF
phials has been ordered by the governor
Of Belgian Congo.
Petit used both African monkeys and
a horse to prepare his serum. After
four or five injections OF an emulsion
of the virulent liver of a monkey dead
of yellow fever the serum of these
African monkeys acquires marked neu-
tralizing and immunizing properties"
Serum from a horse which received
weekly injections of yellow fever virus
acquired the same properties at the end
of three months.
Twelve small Asiatic monkeys were
tested by Petit and Stefanopoulo to
make sure that the serum had pre-
yentive and curative effects.
Two monkeys served to test the viru-
ience of the yellow fever incubation.
One died the sixth day of yellow fever
end the other got well after severe
attack.
None of the other 10 experimental
upon was infected with yellow fever.
All Of them resisted another inoculation
Of virus given two weeks after the first
inoculation.
NEGOTIATIONS Caused Panic.
Petit worked in the beginning with
congealed yellow fever virus put at his
disposition by Prof Andrew Watson
SellardS of Harvard University, to whom
Petit paid a warm tribute for his
shining example of scientific spirit and
humanitarian solidarity"
This was most important, since 1t Is
no longer possible for scientists to work
in Africa under conditions which killed
Adrian Stokes, Young and H. Noguchi,
The incubation of monkeys there caused
a panic after these three men fell vic
tins to their own experiments and the
local governments no longer allow the
incubation of large groups of monkeys.
1t remained for Sellards to devise the
Ingenious method of congealing the
virus, enabling scientists far from CEN
ters of yellow fever to study it.
Petit and Stefanopoulo also diScov-
cred a vaccine for yellow fever, which
they were experimenting with when
Prof Hindle announced discovery of a
successful vaccine. According to pro-
cedure among scientists, the priority be-
longs to Hindle, who announced his dis
covery IA days before Petit and Ste
tanopoulo.
Petit said that he has definitely dis
proved the theory that spirochetes are
the microbes of yellow fever, which was
held by many scientists in accord with
the Rockefeller Foundation scientist,
Noguchi Petit thinks that students
must return to the conception of an in
visible, fltering germ.
