fILAUDETS PHOTOGRAPHIC, OR DA-
IL/ GUERREOTYPE PORTRAI I'S, are taken daily at
the ADELAIDE GALLERY, LOWTHER ARCADE, by
his New Patented Improved Process. The acknowledged su-
periority of Mr. CL A UDET'S PORTRAITS is due to the
surprising RAPIDITY of the PROCESS, which gives to
the Likeness the pl.-asing and unconstrained expression which
the Sitter can only assume during an INSTANTANEOUS
OPERATION—T 9 THE INTRODUCTION of BACK
GROUNDS (EXCLUSIVELY HIS OWN}, representing
Landscapes, Int.rior of apartments, Bc.c., which produces the
most PTTURESQUE EFFECT--and to the mode of durably
fixing the image, so that it cannot fade or change colour, or
be easily rubbed off.

Mr. CLAUDET has also a peculiar process by which Na-
tural Colours are imparted.

QIGHT AND HEARING TESTI-
LY- MONIALS on the Messrs. S. and B. SOLOMONS'
newly-invented SPECTACLE LENSES and INVISIBLE
OPERATIVE VOICE CONDUCTOR for Deaf Persons.
tt We, the undersigned, have been for some time making
tve of Messrs. Solomon? 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
riche 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. Solomons, 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
wit'l distinctness.

These important new inventions are patronized by their Ma-
esties the king and Queen of Hanover and their Royal 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.
