From a i.lte London Pafer.

.Y,roalaslpn.---Th following are the par
ticillars given by Mr. Green Of the phenom-
ena observed BY him during his late ascent:
lie states, that from the stormlness OF the
weather, he entertained serious apprehen-
sions lest, in raising from the ground, the
balloon should be driven against one or oth-
er of the surrounding houses, and in order
to guard against sucn calamity, caused it
to be inflated considerable beyond the extent
originally intended. BY this precauton
they gained an ascending power, which car
ried them rapidly, and almost perpendicu-
Iarly, to considerable elevation, when en-
tering cloud they lost sight of the earth
They coatinued for some minutes 60 pass
.hro' a succession OF clouds which were piled
one above another, those lowest being, as
usual the most dense and opaqne, and at last
emerged into pure cxpanse, IN which not
cloud or vapOur was to be seen, and where
the sun was shining with the utmost brilian-
CIV. They soon experienced excessive heat,
the rays of the sun being concentrated, and
reelected back upon them from the clouds
below, and the thermometer. which few
ninutcs before was below SO, rose rapidly
to 20 The expansion of the gas produced
by this increase of temperature Was so
great, that although the valve was opened to
It's greatest extent to admit its escape, they
still continued to ascend, and in II minutes
from the time Of quitting the earth, they
found themselves at the height CT nearly 2
miles above its surface.-Ehc barometer,
which had stood at 23 deg. and 7-lQths OIL
their rising from the ground, was now found
to have sunk to ? and 3-1Oshs. On looking
down from this elevation at the clouds thro'
which they had passed, Mr.. Green says,

by two haloes, presenting, with the utmost

dred wards from the reflected balloon, and
the other about twice as far. The former
was the more brilliant. The clouds in which
this curious Illusion was observed were about
3OUgfeet distant MIR. Green states the appear

er remembers having seen it when the sun
was more than SO or less chan 40 degrees
above the horizon. II is not often, hoWcv-
er, he saws, that the coors are SO VIVID as on
this occasion. The illusion did not cease
during the whole time they remained at tins

stated that birds let loose at this height be-

long as they remained in sight of the aron-

turned home, without appearing to be 10
the least exhausted. After continuing at
this elevation nearly an hour, Mr. Green
commenced his descent, and III abeut
quarter of an hour was sufficiently near the
earth to be able to ascertain that he was
floating over part Of the Kent; but on de-

on the estate of Joseph Martin, Esq. at kain
ham near Barking. Several gentlemen III the

houses, but Mr.. Green, anxious to convince
his friends in London of his safety, declined
their invitations.
