EXPERIMENTAL. TRIP OF TIE ERIAr Ma.
ouNE.--An account has been forwarded 10 u
from Scotland ofan experiment tried few DAYS
! ago, near Glasgow, With machine constructed
on the same principle as that of Mr.. Henson
The experiment was made by a Professor Ge-
OILS, foreigner, and but for an accident, Il ap.
pears would have established the principle con-
tended ior-Tiz tile capahilily of navigating
the ar. Not wishing, however, to make any
misrepresentation upon the point, we give The
particulars from a nauative drawn up BY Pro-
lessor Geolls himself. The Professor after sta
ting that he constructed bis machine in exact
accordance with Mr.. Hensons speciication,and
that be had paid great attention to al the cir
cumstancos connected with the fight Of birds,
says he fixed upon the bin Of Dumbuck, near
Glasgow, for the trial He then proceeds thus:
"The nra machine was properly placed at
an altitude Of $50 lineal feet from the earth,
and fixed at the top, near the flag post in the
usual way being held by daggers, perfectly
similar TO those used by shipbuders, and only
requiring one blow Of the maui 10 free It and

all complete, and every thing ready for my I'M
usual and interesting fight.

liberated the machine, and away she shot with
the speed Of lightning. Before she reached

which exactly conceded with my calculations

descent down the plane, but from the operation
Of the vertical tanners (the engine having been
SGT going simultaneously with the precipitation
of the daggers,) she had began 10 hf, and on
clearing the brow, had, in fact, risen a few
yards, as was plainly indicated by the falling

confidence, and enabled me to make a few ne.
