CPECTACLES-My attention mas oeen called to
~ article in the public papers and circulated in
handbis about this city, called Perocal Spectaces,
said to be constructed in accordance with the phi
losophy Of nature, in the form Of Concavo Convex
Ellipsis What is meant by the philosophy of nature
may be hard to tell but certainly they are at variance
from the laws principles Of Optics, as certainly no
Elpsis can converge the rays OF light to perfect TO-
Gus They are said not to be the French meniscus
or Wollaston's periscopic Zone and the same con-
struction Of glasses.) The menscus lens is truly
ground surface, concave side; the other side,
possessing greater degree of sphercity, consequent
" becomes magnfying glass. This species Of glass
will converge the rays of light the as double
convex lens. The application Of this form Of lenses
in the shape of Spectacles, gives the eye greater
field of vision. l1., iA
The celebrated DR.. Brewster, in speaking of these
Spectacles says that they give decidedly more spe'-
feet visions than common spectacles, because they in
crease both the alteration Of figure and ofcolor; but
they may be Of use in crowded city in warning us
of the oblique approach Of objects. Now, as spec
tacles are intended to assist nature, and the Eye,
the most perfect masterpiece of Divine Mechanism,
Gin its natural state,) every part has the very form
and office which the laws Of optics require for the most
perfect vision of an object Is it not preposterous TO
apply piece of bent concave or convex glass with
out true form figure to its assistance! On the con-
rary is it not reasonable to conclude that their
tnued use would destroy the eye entirely' Specta-
cles are probably the most ancient of all optical in
struments and yet has undergone the least change OF
any, The subject has been well considered by Opti-
clans throughout all Europe for ages, and the general
conviction is that truly ground concaye or convex
lens is the most suitable for assisting decayng or un-
natural visions of the human eye, R. PATTEN. +
