SIGHT AND HEARING.

THE INVISIBLE OPERATIVE VOICE
CONDUCTOR, effected by the Messrs. S. and B.
SOLOMONS Opticians and Aurists to the Royal Family, 39, Albe.
marie-street, Piccadilly, by which thousan4s of deaf persons have
been greatly benefited, is the size of a seven-shilling piece, and when
fixed into the cavity of the ear is soft and easy, and not morepercep.
lible than having a piece of wool in its place, by which the faintest
whisper at a public assembly is heard with distinctness. And defec-
tive VISION is brought to nature by the use of newly.invented
SPECTACLE LENSES : immediately they are placed before weak
and imperfect eyesight, either by day or candle light, every object
bccomesclear 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. SOLOMONS DISCLAIM all connection with persons
of the SAME NAME, and the sale of Amber Spectacles: in doing
so*they state the HISTORY of AMBER, from the Dictionary of
Arts and Sciences" of Andrew Ure, M.D., F.R.S., &c. &c.
" Amber is an indurated vegetable ju'ce, and not produced by the
laws of crystallization, but by the same causes which influence the
mechanical condition of gum. InseMs are often found embedded in
it. Amber is most powerfully electrical by friction—very hot, to
such an extent as to explode into fragments ' • the workmen, too, are
subject to nervous tremours in their wrists, arms, &c. ; they en-
counter great danger 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 D
BREWSTER and Pliny, as also by Parks and Heny on Chemistry.
Thedestructive effects of such a material for Spectacles, to imperfect
vision, are fully and most satisfactorily explained in Messrs.
Curtis and Dollond's Second Edition on the Preservation of Sight,
and Tay be ascertained at any respectable Opticians in London.
The D, essrs Solomons' newly-invented Spectacle Lenses are not
constructed of such a material; but which are very superior, and
