bite OF the mosquito or by the iniec.
ton of blood taken from the general
circulation. From this the important
oarolary is reached, to quote DR..

destruction of the mosquitoes and the |

In the malaral investigations, the
only mosquitoes which have been
found to carry the disease are those
Of the genus Anopheles. The malarial
germ seems to die in the stomachs of
the commoner mosquitoes of the genus
Culex. With yellow fever. so far as
the investigations have gone, but one
species of mosquito has been found 10
transmit the disease. This Is the
form known as Stegomyia fasciata.
formerly placed in the genus CuleN.
This mosquito is a southern form, and
its geographic distribution corresponds
very accurately Win tHt stOSIdpii'
distribution of the disease. It Is com.
monty found in our Southern States,
and is abundant throughout tropical
regions. II Is a mosquito which read.
| lily accommodates itself to city con
L.tions. and breeds freely in the cess.
pools. rain water tanks and barrels.
and places of similar nature. 1t
thus abounds in southern communities.
One of the most interesting differences
in the habits of this mosquito and the
notwithstanding forms. and one which
has some practical significance. IL
that. while the malarial mosquitoes
seem to fly and bite only at night, the
yellow fever mosquito Is popularity
termed In many southern regions the
DAY mosquito since 1t bites In .he
afternoon as well as at night It will
be remembered that the malarial ex.
perimenters on the Roman Campagna
walked about the neighboring country
during the day and retired to their
mOsquito.proof house only at nightfall.
but In yelow.fever country 1t is
wise to protect ones self against mos
quito bites by days as well as by night
The incredulity which was felt Ivy
many, and which was expressed by
certain journals after DR.. Reeds first
announcement of the preliminary work
of the commission, at the meeting OF
the American Public Health Associa
tion in indianapolis last October. has
passed away since the publication OF
his last paper, read before the Pan
American Medical Congress at la
vana early In February Of the present
year. The paper itself is conclusive
but the modest way in which DR.. Reed
has told the story of the magnificen,
results achieved by himself and by
his colleagues. while exact and scien
tifc. does not impress the avera &C
non.medical reader with a due sense ri
its importance. But when one learns
of the enthusiasm with which DR.
Reed was received by the Johns Hop
kins Medical Association and by Ri,
Medical Association of TIE District ci
Columbia. and when ore talks. as III,
writer has done, with physicians from
Central America who were present al
the Pan.American Medical Congress N
Havana. and with those who assisted
! IN this great experiment. one canno
fail to believe, not only in the sound
ness of the conclusions, but in tn,
, transcendent importance of the dis

Anti-Mosquito Work.
Practical anti-mosquito work wa,
undertaken in Cuba Immediately fol
, lowing the formulation of these con
, illusions. General orders were issueC
requiring the universal use of mosGui
to bars in all barracks, especially II
hospitals, as well as In field serv;c,
where practicable. The drainage %
breeding places. the use OF petroleum
on standing water. in which mosqui
toes breed wGs directed. and the med
!cal department Of the army furnished
, oil for this purpose. II has resulted
, that Havana had less yellow fever dur
ing the present year than at any tim,
in its history. Not single case ha.

May last and. incidentally. malaria
fevers have been greatly reduced.
