Sir Patrick Manson, K. c. NJ. G., F. R.
s, etc, the worlds greatest authority
on the relation OF insects TO the trans
mission OF disease and the first TO point
out the role of the mosquito in pathol
ogy, began a series of nine lectures be-
fore the students of the Cooper Medical
College last night.
Sir Patrick addressed the scientists
on Tho Biological Factors in Tropical
Disease, Exemplified by Epiphytic Dis
ease; Ankylostomiasis, and explained
the symptoms, results and causes of
the mysterious sicknesses transmitted
through insects.
Because of the acquisition of tropical
country by the United States, with the
policy Of future expansion tending to
more of the same territory, it was
pointed out, the study of leprosy, sleep
ing sickness. yellow fever, aenemia,
Will take an important place in the cur
riculum of medicine in fitting men for
practice in such regions.
The lecturer told of the prophylactic
measures necessary to insure the pro-
lection of the inhabitants of tropical
countries from the diseases that annu-
ally caused the death of many of the
afflicted He was emphatic in speakin 6
of the part the mosquito plays in the
cause and transmission of disease. The
great amount of work he had accom-
plished has been in the line of eradicat-
ing the winged pest
In introducing the lecturer, President
EllinwoOd of the college referred to

told of the purpose of the school to get
the very best men TO advise the stu

"A great many insects are agents of
transmitting disease germs" the lee
turer said. but to the mosquito the
greater blame can. be laid. Malaria is
the sickness usually caused by the
presence of this insect but there are
many others also that have found their
way into pregnable parts of the sys-
TENS of humanity" Continuing, he
said:
The field open to the student of tropical dis
eases presents enviable opportunities since the
possession OF the Philippines has come into the
hands Of the United States, and the islands
around the gulf also. Sanitary conditions are

sanitary conditions is a great study in itself.
Certain germs are peculiar to the region in
which they found and will not exist in
other regions. The disease germ exists best in
the human body because OF the even tempera-
ture there and the favorable conditions under
which il multiplies.
The ankylostomias germ is deadly in effects
after IL once gets footnoId. appearing from
time time the plantations in tropical
ciinles II causes anaemia and later death.
Persons are stricken with II by the attack OF
the anlyslcstomia insect The rapidity with
which il Teproduces offspring soon infects the
whole body with deadly effect.
II at first supposed that the insect found
entrance TO the system through the alimsntary
canal or mucous membrane. but it has been
found upon investigation, that it enters
through the skin wherever it happens to light.
