THE INVISIBLE OPERATIVE VOICE
CONDUCTOR, effected by the Messrs. S. and B.
SOI.OMONS, OPTICIANS and AURISTSto the ROYAL
FAMILY, 39, ALBEAIAR LE-STREET, PICCADILLY,
by which thousands of deaf persons have been greatly bene-
fited, is the size of a seven-s hiding 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 per vicious use of amber spectacles
being now well knriwn to the public, and tile 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 " Dietionary of Arts and Sciences" of Andrew Ure,

F..R.5., &e., &c.
" Amber is an indurated vegetable juice, and not produced
by the laws of crystallisation, but by the same causes which
influence the mechanical condition of gum. Insects are often
found embedded in it. Amber is most powerfully electrical
by friction—very hot, to such an extent as to explode into frag-
ments ; the workmen, too, are subject to nervous tremors in
their wrists, arms, &c. ; they encounter great dangerby handling
such dreadful excited elect ries ; amber grows with lime, and is
apt to take file, and is of such a soft nature when exposed to
warmth, that it swells, babbles 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 Berns, 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 isatural state. These Spectacles, and
very small Voice Conductors for deaf persons, are r.ly to be
had at their establishments, S 9, Albemarle-street (opposite the
York Hotel), and 76, King William-street, Bank.

THE NEW COUGH MEDICINE! ! !
IIOLLAND'S BALSAM OF SPRUCE,
the newly-discovered remedy for COUGHS, COLDS,
INFLUENZA, INCIPIK NT ASTHMA, and CON-
SUMPTION.
Medical Science is daily pros luting new wonders, and among
the discoveries which take plat !e none are more deserving of
public approbation than a rern.!dy for those complaints which,
in this variable climate, are so productive of fatal consequences
to the comfort and lives of the public as Coughs and Colds.
This Extraordinary Remedy ;relieves the most distressing
symptoms in a few hours, and a little perseverance in its use
will, in every case, effect a permanent cure.
Coughs and Colds, acco npanied by a difficulty of breathing,
soreness and rawness of the chest, impeded expectoration, sore
throat, and feverish symptoms, will be quickly subdued, while
its use will assuredly prevent consumption from this prolific

cause.
Holland's 13alsam of Spruce gives immediate ease in all
Asthmatic cases, and particuli irly in Hoarseness, Wheezings,
and Obstructions of the Chest ; while those who have laboured
for years under the misery of a confirmed Asthma, have been
enabled by its use to enjoy the blessings of life, and to pursue
their avocations with a degree of ease and comfort they had
been strangers to for years.
