provide Il mosquito proof hut to be set
up in the worst part OF the Roman
| Campag na. y spot was selected near

which is So infested by malaria that
no one who spends n night there under
ordinary conditions escapes the effects
of the poison. DrS. SambOn and Low
of the School of Tropical Acdiciee and

sunset they remained i'll the hut. They

might he regarded as a prOphylactic.
| InaSmuch as the ''nLalarial' season

the experiment is not yet finished.
The Omcns for success, however, are
propitious.
\ rumor having been circulated n
Italy that the experiment had proved
Il failure the British Medical Journal
made inquiries at the School of Tropi-
cal Medicine At its instance the ten
ants OF the mosquito proof hut were
visited on Sept. l. by Professor Grassi,
who was accompanied by. DrS. Voc
and Foa, his assistants. by Professor
ROSSi of Cagliari and by DR.. ZupitZa,
assistant to Professor Noeht at the
Hamburg School of Tropical Medicine.
The result was the following telegram
TO DR.. Manson:
Assembled in British mosquito proof hut, and.
having verified perfect health Of experimentcrs
smid malaria stricken inhabitants, Italian doc
tors salute Manson, who first formulated mosquito
EI1ldrial theory. GRAssI
Commenting upon this the British
Medical Journal says: I'VE may now,
with as much confidence as the uncer-
tainty of human things warrants, look
forward to Il successful completion of
this important experiment. 1t is clear
that if the formula, No mosquito, no
malaria does not contain the whole
truth of the matter. it may for prac
teal purposes be taken as n guiding
principle by colonists and pioneers in
tropical Chimes"
What may be regarded for practical
purposes as an experiment Of the same
kind as that not yet completed in the
Roman Campagna is now being con-
Quoted in west Africa. DR.. Elliott, q
member of the Liverpool expedition

tigate the subject of malarial fever. has
recently returned to England. He re-

ton have been perfectly well, although
they have spent four months in some

off by the use of Quinine, but they

AS a compliment 10 the preventive
experiments in the Campagna, it was
arranged that attempts should be
made to prove that malaria would be
contracted by a perfectly healthy per- |
son, who had never entered a ''malar- |
ious'' locality, if he We're bitten by |
