SIGHT AND HEARING.

( Opposite the York Hotel), and
76, KING WILLIAM-STREET, BANK OF ENGLAND.
THE INVISIBLE OPERATIVE VOICE
CONDUCTOR, effected by the Messrs. S. and B.
SOLOMONS, OPTICIANS and AURISTSto the ROYAL
F 39, ALBEMARLE-STREET, PICCADILLY,
by which thousands of deaf persons have been greatly bene-
fited, is the size of a seven-shilling piece, and when fixed into
the cavity of the ear is soft and easy, and not more perceptible
than having a piece of wool in its place, by which the faintest
whisper at a public assembly is heard with distinctness. And
defective VISION is brought to nature by the use of newly-
invented SPECTACLE LENSES; immediately they are
placed before weak and imperfect eye-sight, either by day or
candle light, every object becomes clear and distinct, and the
most minute particle is seen with great distinctness ; by the use
of which both the sight and hearing become much improved.
The Messrs. S. and B. SOLOMONS disclaim all con-
nexion with persons of the same name, and the sale of am-
ber spectacles ; the pernicious use of amber spectacles
being now well knawn to the public, and the vendor being
aware of it, he has therefore altered their name, by leaving out
the word " Amber,' and calling them " Patent. Spectacles."
Those which he terms " Patent Spectacles" are no other than
those of amber ; the history and destructive use of that mate-
rial for Spectacles to imperfect vision is fully and most satis-
factorily explained by the undermentioned scientific authority :
From the " Dictionary of Arts and Sciences" of Andrew Ure,
M. D. , F. R S., &c., &c.

" Amber is an indurated vegetable juice, and not produced
by the laws of cry:'allisation, but by the same causes which
influence the mechanical condition of gum. Insects are often
found embedded in it. Amber is mast powerfully electrical
by irictioi.--very 713 t, to such an extent as to explode into !rag•
ments ; the workmen, too, are subject to nc• vous tremors in
their wrists, arms, &c. ; they. encounter great t.anger by handling
such dreadful excited electrics ; amber grows with lime, and is
apt to take fire, and is of such a soft nature when exposed to
warmth, that it swells, bubbles up, and will burn away with
flame."

The above Dr. Ure's statements are further confirmed by Sir
13. Brewster and Pliny, as also by Parks and Hems, on Che-
mistry. The destructive effects of such a material for specta-
cles, to imperfect vision, may be ascertained at any respectable
Optician's in London.
The Messrs. Solomons' newly invented Spectacle Lenses are
not constructed of such a material ; but which are very supe-
rior, and bring back at once dimness of sight and imperfect
vision to its original and natural state. These Spectacles, and
very small Voice Conductors for deaf persons, are :r.ly to be
nad at their establishments, 39, Albemarle-street (opposite the
York Hotel), and 76, King William-street, Bank.
