he had chilly sensations, followed by
fever and restlessness during the night.
On the following day Seventh day af-
ter 1noculatiOn), the patient was removed
to the yellow fever wards. His attending
physician, DR.. Roger p. Ames, II. S. A.
an expert in the diagnosis and treatment
of yellow fever, did not hesitate to dag

nounced yellow fever" DR. Ames was
not cOgnizant of the method of inocuia-
ton in this case.
AS in DR.. CarrolPs case, the move
ments of this patient for period preced-
ing the attack were traced, and no other
cause for the attack other than the bite
OF the mosquito could be found.
From these three cases the board drew
this conclusion: 1.-THE mosquito serves
as the intermediate host for the parasite
OF yellow fever, and it is highly probable
that the disease is only ropagated
through the bite Of this insect"
COULDN'T FIND SANARELLTS BA.
CILLUS.
AS DR. Sanarelli the South American
phslcian, has announced that in bacillus
1cteroides he had found the cause of vel
low fever, the board tried to find in the
blood of yellow fever patients this ba-
clllus, cultures being taken from the
blood during life and after death. But
from forty-eight separate cultures made
from the living blood at various stages
OF the disease they failed t. find the
accused bacillus. The board says:

his associates in not finding any thi,
