FOR THE SUN.

Mr. ttirroa,-v.,Allow me. thrbttgh the channel
of your Paper, to congratulate the public on, that
very ingenious and amusing (whether equally use,
lid or not yetremmius to - he.proved) inveotiou,
the Katiedescope (query, whether or not more
properly Kalleascope, xa)o,..sa poretv). A more
pleasing exhibition to the eye can hardly be of-
fet ed ;- it is .really,magical, and may be compared
to the stories of the Arabian Nights Entertainments
it combines all the novelty, va.riety, beauty, and
brilliancy -which this age is so eager alter, anti
certainly so capable of appreeiating; and the gra-
tification it affords is attended with no moral evil,
for the curiosity it excites is only that of knowing
by what means so extraordinary an effect is prof
duced, so much order out of confusion; for, sim-
ple as the construction of the instrument appears
to be—(l confess I have nor taken one to pieces)
—the principle sou which it is founded must, 1
imagine, be munch more complicated. Ii I may
venture upon a definition of it, I should call it the
Art of multiplying and arranging Reflection. Flow
far it is allied to the problem of the (1 think)
cylindrical mirror I know not. 'fesselated pave-
ments and paintings on glass seem to be the most
probable objects of its
.application ; possibly it
may suggest other ideas still more surprising.
At any rate the ingenious inventor surely deset ves
our thanks for this innocent and rational audition
to our amusements, as the beautiful illusion of
his- colotirs and forms does all the-eclat they can
receive from the mention of them being inserted
in TH E Sum.-1 am Sir, yours, &c.

***Urt shall be glad if any of onr scientific
Readers will favour us with their explanations
and opinions on the Subject of the very amusing
instrument above mentioned, as it seems at pre—
sent to be an object of universal curiosity and
attention.

ft has been hitherto considered a Principle in
Mechanics, that-'< whitt is gained in Power is lost
in Time ;" but by the recent constrnction of, a
Wheel, which will soon be publicly in m tion,
this principle, seems completely changed, as the
power at a youth only 12 years of age raise
from it a Thousand Pounds, per moose ; and
whoever has a Share in this capital movement,
must be convinced that the ftiction of poverty:it
effectually overcome, for the wheel contains 107
Capital Prizts, including three of 20,0001. and
the first 20 Prizrs drawn on the King's Birth-
Day, when this Grand Lottery begins, will re.
.ceive 10001. each is addition.
