had bitten mid case of yellow fever
(first day. two days before being APP
piled to X. Y.
X. Y. was also bitten by a second
mosquito that had been applied to a
fatal case of yellow fever (second day.
twelve days before; and to two mild
cases (second day. four and ten days
previously; also, by third mosquito
that had bitten a fatal case of yellow

Il severe case Qirst day. two days be-

and third day. four. six and ten days
before. finally by a fourth mosquito
that had bitten three severe cases of
yellow fever Gall on first day.. two, four
and eight days previously, and one mild
case Second day. six days before.
1t will be seen that X. y. was bitten
by four mosquitoes, two of which had
bitten severe fataD cases of yellow
fever twelve days previously; one of
which had bitten a severe case Second
day.. sixteen days before, and one which
had bitten a severe case eight days be-
fore.
X. Y. began to experience Il sense of
dizziness and Discrimination to work
This was just five days from the time
of the mosquito inoculation; twenty
four hours later he was still dizzy and
light headed in attempting 10 move
about. During the Afternoon (siXth day
after inoculation) he had chilly sensa-
lions, followed by fever and restlessness
during the night.
On the following day (sev >nth day
after inoculatiOn), "a. m, temperature
was 1928 degrees Fahrenheit, his eyes
were slightly injected and his face suf-
fused. The patient was removed to the
yellow fever wards; at a. m. temper
allure was 103 degrees Fahrenheit, pulse
&C. The conjunctivae We're slightly jaun-
diced on the fourth day of the disease,
which was more distinct and could be
plainly seen on the anterior aspect Of
the chest on the fifth and following
days. Bleeding from the gums was no.
| ticed on the third and subsequent days
after admission. Repeated examina-
| tons of the blood failed to show any
malarial parasites.
The course of the fever, the appear
dIlNe VI StiDulHeH III LIle uTlle, WITH
jaundce and hemorrhage from the
gums, together with the slow pulse all
! pointed distinctly to the diagnosis Of
| yellow fever. His attending physician,
| DR.. Roger p. Ames, II. S. A., an expert
| in the diagnosis and treatment of this
| disease. did not hesitate to diagnose
] \. US attack as one of well pro-
| nounced yellow fever" DR.. Ames was
| not cognizant of the method of nocua-

In the light of these two cases we
| consider that of DR.. Lazear of sufficient
Importance to be here included, espe-

Sibl ydesignated sd case of accidental
infection bW a mosquito.
DIR. Jesse w. Lazear, acting assistant
surgeon, United States army, a member

which ten days previously had been con-
taminated by biting a very mild case
of yellow fever Uifth day.. No appre-

this incubation.
On September IS Ceremony Dr. La
