QIGHT AND HEARING. - TESTI-
MONIALS on the Messrs. S. and B. SOLOMONS'
newly-invented SPECTACLE LENSES and INVISIBLE
OPERATIVE VOICE CONDUCTOR for Deaf Persons.
" We, the undersigned, have been for some time waking
use of Messrs. Solomens' newly-invented Spectacle Lenses ;
the astonishing relief they afford to imperfect vision gives
them the decided preference to every other kind' of Lens
—the clearness of the transparency brings every object very
distinct, and enables individuals to view the most minute par-
ticle with perfect accuracy. They are particularly pleasant
by candle light, as they appear cooling to the sight, and soften
bright and brilliant lights :

In placing the above list of Testimonials before the public,
the Messrs. Solemons, Opticians and Aurists, state that their
INVISIBLE OPERATIVE VOICE CONDUCTOR, by
which thousands of Deaf Persons have been greatly benefited,
is not larger than a seven-shilling• piece, and when fixed into
the cavity of the ear is soft and easy, and not more uncomfort-
able nor perceptible than having a piece of wool in its place.
By its use the faintest whisper at a public assembly is heard
distlnctness. . .

These important new inventions are patronized by their Ma-
jesties the King and Queen of Hanover and their Bo -is' High-
nesses the Princesses Augusta and Sophia, her Serene High-
ness the Princess Esterhazy, the Princesses Mary and Rosa,
her Grace the Duchess Dowager of Bedford, and their Graces
the Archbishop of Canterbury, the Dukes of Devonshire and
Manchester, &c. &c.
