WASHINGTON, March 12.--Dr. Louis
Il Dehaslc the delegate of Nicaragua
and several other Central American coun-
tries at the recent Cuban Medical Con-
Eress is in Washington as the guest OF
the Nicaragua Minister. Senior Corea-

medical delegates recently assembled in
Cuba were Impressed by the remarkable
sanitary improvements going on through
the enterprise of the Americans, and par

INTERESTING EXPERIMENTS.
The experiments on yellow lever arc
being conducted lust outside of Havana,
said he under conditions which make
most exact results attainable. Certain
apartments are filed with yellow fever
Nth of all kinds. with a degree OF temper
ature and an amount OF moisture eSacltS
similar TO the conditions which breed ycl-
!aw fever Here animals, and in some
cases medical men, expose. themselves,
with a view TO determining just how far
contagion and infection can be spread
under the worst possible conditions. in
other apartments the best sanitary con-
1iuons prevail. except in the presence OF
mosquitoes. confined in jars, and allowed
20 circulate through the room when an
experiment is being made.
1T has been demonstrated beyond a
doubt that these mosquitoes when once
lnoculated with the yellow fever, COM
municatc ii by their bites. the disease de-
Neloping in from two to three days. IN
another room there is another class OF
mosquitoes. which by actual experiment
have failed TO convey the disease. In the
rooms where yellow fever filth is located,
individuals have lived for from thirty to
fifty days. showing that there Is no
danger from this cause. AS d result OF
these American! experiments, the dele
gates 10 the congress We're OF opinion
THAT the ascertainrcnt of the cause OF
yellow fever had gone beyond the expert
mental stage. and that il was now all &C
cepted medical fact that particular class
Of mosquitoes conveyed the disease.

that this was absolutely the only means
of communicating the disease, but 1t. is

in yellow fever localities Such a con-
clusion is not only of Importance to Cuba,
but TO all countries similarly affected as
well as 10 the United States and other
adjacent territory likely to be invaded
by such plague.
Already the American administration
has established this valuable scientific

four or five cases of yellow fever in

as two cases. which is an exceptionally
good showing.
The Americans are 10 be conEra tulated
also on the excellent sanitary conditions
throughout Havana. Modern sanitation
has been carried INTO every house, perfect
methods of plumbing, taking the place
Of defective and dangerous old systems.
The streets are kept scrupulously clean.

CubanS have Il natural aspiration for
self-government, although they are quite
willing to concede guarantees to the
