of him has long been the puzzling
question. Dr.. Houseal says it should
be made n1isdemeanor for anyone to
have the pestiferous little singer on
his premises. That it causes the ma
laria which is prevalent in many Sec
tions and is generally very danger
Gus thing not to speak of the annoy
ance which it gives those who want
to sleep. We print below a full re-
port of lecture delivered by Dr..
Houseal before the student body of
Newbery college on last Thursday
morning on the mosquito. 1t is an
interesting exegesis of the history,
life and habits of the mosquito and
we. feel sure it will be read with in
terest. Dr.. Houseal said in part:
1t is now known that mosquitoes
are culpable in spreading several dis
eases, viz: Elephantiasis, Filaria san
guinis aaomino, malaria and yellow fe-
yer. And recently Blanchard has pro-
duced strong arguments to prove that
leprosy is spread by them.
In order to get into this subject
thoroughly it is necessary to know
something of the history of this i'm
portant discovery.
In 1717 Lancisi of Rome held that
marsh lands are noxious because Of
the emanations coming from them,
which he divided into inorganic and
organic. By organic he means the
numerous insects which develop in
marshes, the mosquito especially. In
1880 Manson showed the connection
between Elephantiasis and Hosqui-
toes. In the discovery by Lavaran in
1880 of the 7nalarial parasite, which
causes the disease malaria, lay the
promise OF the most potent gift the
laboratory had ever given to mankind
tine destruction of the disease mala-
ria. In 1883 King, of Washington, at
tracted attention by arguing the con-
nection of mosquitoes with malaria.
Ross, an English army surgeon, in
India made possible the promise that
lay in the discovery of Lavaran-the
Punishment of malaria from the earth.
From 1895 to 1899 he demonstrated
by the most rigid scientific expert
ment that malaria is contracted alone
by the sting of the mosquito. About
the same time Bignani of Rome dem
onstrated by many rigid experiments
to the entire satisfaction Of the scien-
tific world that malaria is contracted
alone by incubation through the bite
Of the mosquito.
In 1881 Finley suggested the rela-
ton between the mosquito and yellow
fever. In 1900. the American COM
mission composed Of Drs. Reed, Car
roll, Lazier and Agramonte was sent
by the American government to Ha-
vana, Cuba, to study yellow fever and
demonstrated that yellow fever is
contracted only by the bite of the
mosquito, stegomyia fascita. Two of
these doctors offered themselves VOL
unfairly for the experiment. DR..
Lazier took the disease and lost his
life, becoming a martyr to science.
Up to this time three hundred kinds
of mosquitoes have been discovered
Thirty-six kinds have been found in
North America, of these the culeS
genus is most numerous, next the
anopheles, 5 kinds, and the stegomyia
three kinds. The anopheles is
the kind that spreads malaria. The
word anopheles if from the Greek
which means injurious. The anophe-
les may exist and not necessarily ma
laria. The insect must be infected by
the malarial parasite, but no anopheles
no malaria. The anopheles is readily
distinguished from any other variety.

varieties sit with the body parallel to
the wall.
