no doubt, If they were thoroughly tried,
that success would crown the efforts
the breeding places. there was the coal
1 oil remedy. Coal oil put on the top of
standing water and allowed to spread
over all the surface would surely ex-
terminate the mosquitoes. The wrig-
glers, by the law of their being, had
to come to the surface to breathe, and
they could not breathe through the
coating Of coal oil over them and must
therefore die. Where it was inexpedi-
ent to put coal oil on the surface of the
! introduction into such places of fishes
! that fed upon the larvae would meet
the difficulty. For this purpose there
was the gold fish, and other varieties
of fishes native to the islands. If nee
essary fishes could be imported for this
purpose. The speaker had found that
in those taro patches where there were
gold fishes no mosquitoes were bred.
Lastly, there was the remedy of filling
up and emptying out the breeding
places. This was most effectual of all.
All mosquitoes must breed in water.
If the water was thrown out and the
place made dry the eggs and the young
insects would die. AS to the disease
carrying mosquitoes, they only breed in
fresh water, and where pond was sus-
pected it could easily be made brackish
If it were close to the sea.
MI Van Dine closed his lecture with
series of most interesting lantern
slides illustrative of mosquitoes and
their personal peculiarities. The society
gave him vote of thanks after he
had concluded.
Then DR.. Day took the floor for his
talk upon the medical aspects of the
mosquito nuisance. He closed with the
verse that begins this article but be-
fore he got to that he had told in de-
tail and most entertainingly how it was
discovered that the Pontine marshes,
virtually uninhabitable by reason of the
presence of the mosquito that carried
the germ of malaria, and how a physi
clan, demonstrating that fact to the
Italian government in his own person,
his son serving him as a volunteer in
permitting himself to be inoculated in
London by being bitten by mosquitoes
from the marshes and developing from
their bites a we'll marked case OF ma
laria, had been SO conclusively sue
cessful as to establish a great fact in
medical science. From that DR.. Day |
went into the history of the expert |
ments made at Havana by the army |
surgeons, in the course of which, it |
will be remembered, several of the |
volunteers, non-immunes, who had per- |
quitoes that had bitten yellow fever |
patients, died of that scourge. But |
they had died in the service of their
fellow men. One of these, let the fact |
be borne in mind, was himself a sur |
geon, eminent in his profession. The |
result of these experiments had been to |
establish, beyond all doubt, that mos
quitoes of a certain variety did carry |
yellow fever germs-and that fact being |
established, it had been possible prac-
ticaIly to wipe out the fever by an in
teIligent campaign against the mos
quito. This much science had done in |
that one field for humanity. 1t was a |
matter all the more interesting to the |
people of Honolulu. from the fact that |
the same daylight mosquito was found
here.
DR.. Day was also given vote of
thanks, and after that the doctor, with
his partner, DR.. Wood, proceeded to
give demonstration to the members
of the society and their guests of the
working of the x-ray. One of the doc
tors worked the Crooke's tube machine
in one room while the other, taking the
gentlemen present in relays into an
adjoining room that had been darken-
ed for the purpose. held his hand be-
fore a small fiuorescent screen next the
wall. and the pale, green, ghostly, light.
gathered by the screen, seemed to shoot
right through the solid flesh, showing
the outlines of the bones as distinctly
as though it had been a skeleton hand.
1t was interesting, but uncanny
After this demonstration, light re-
