hsEs-, 80. L. r.

mo- quito must carry the malaria about
with him. Nevertheless, fifteen years
raised without anything being done to
take practical advantage OF this theory.
/ DR.. Ross, the Iudian army surgeon,
discovered in 1898 that mos quit oes
developed in their bodies the proteozo
me Liable, parasite which he showed
caused mslsrisl fever in birds bitten
by them. So the connection was fixed.
lC only remained to discover the action
of the auephole mosquito as tie vehicle
of human malaria, aud this is due part
ly to Dr.. Ross and partly to Dr.. Grassi,
professor OF zoology at Rome.
For ten years past DR.. Grsssi had
seau pursuing his experiments on this
particulsr species of mosquito, when
the dsta Of Dr., Ross suggested to him
tho ulterior researches which ended
IN the decisive result. Ia October,
1898, aided by Drs. Bguami aud Bas
iIanelii, no acquired the certainty that
the mosquito who carried the mslaris
poison vas indeed the anophele. The
parasitic germs which he carries in
him osnuot live when they pass into
birds or domestic animals, but they
live and develop luxuri.nLly in tue
| blood of nan, which has the unlucky
quality of so strengthening and mul i.
ply Ing them that they not only infect
him with malsris, but Gauss him, in
turn, to infect others. Ii is the female
aoophele only which is dangerous. The
male does rot bite.
The conclusive experiments were
made in a hospital hall Of the Ssuto
Spirito, at Rome, On dozen individu
als 10 good health and Of philanthropic
disposition, who allowed themselves to
be bitten by mosquitoes from mslarious
districts.
DE- Grassi rspidly obtained oonfrma-
ton OF the other important fact, that
the mosquitoes themselves oftenest be
como infected By absorbing the blood Of
person sick with malaria. The red
globules Of the blood OF suob persons
contain parasites quite distinct from
those causing sny other contagious
malady. There sre of the class of pro.
toz 1oros, that is to say niJellular
organisms, who obtain their organs or
reproduction only after a singular
honeymoon trip to the stomach Of the
snophele mosquitoes. 1t is there that
the sexual distinction Of these germ.
commences; that is to say, their repro.
duction aud development, Sometimes
tiieir number exceeds 10, 900 in one in
dividual body. According to climatic
conditions they arrive at maturity Iowly
or rapidly. Then the capsule which con.
taius them breaks; they flow into the
vlscero of the snophele, thence into the
salivary glands and thence to the bite
of the insect. The mosquito, when he
bites or pricks us, inccuIstes into the
wound tiny quantity Of this saliva
containing the germs. And as he does
not get rid of his poisonous provision ia
Inject several persons, one alter the
other, in sigle night. One single bite
is sufficient to provoke beautiful case
of malaria which may last man a life
time or carry him to the grave in four
days.
When man is thus bitten and infect
ed the red globules of his blood COM
mence to alter, after about twelve days.
lt Is at this moment that the feVerish
symptoms of chiils and flushes begin to
show themselves. These fevers are
slight or strong, long or short, accord
iDg 10 the mslignity OF the individual
parasites with which he happens to be
incculsted, and according to the season
IN which he contracted the infection.
| In the spring they are lighter than in
summer or autumn. They generally
reappear each succeeding yesr. DIR.
Manson took with him to London a
quantity of infected mosquitoes, which
lie caused 10 bite his son, who had never
Oeen outside Of England in his life He
nevertheless developed typical attack
Of Intermittent fever.
Malaria, therefore, is malady whose
contagious character manifests itself
uniquely in places where there sre sno
phele mosquitoes aud during tho warm
season. Vegetation, temperature.
stagn.nt waters aud marshy ground
combine powerfully to spread the evil,
because they make conditions favorable
for the propagation of both mosquito
and germ, But there are localities
like Poestum-which have become Only
recently infected; and it is clear that
malaria msy be either brought into q
neIghbOrhood or stamped out of IT,
Rome mains for some reason free from
malaria, though surrounded by An in
lee. ed zone Of the worst kind. The
stamping out Of mall aria, which ha
been accomplished In tho towns OF
Metaponta and Slbaris, has become the
great hygientic work Of Italy. Every
thing demonstrates that the disease il
