THE INVISIBLE OPERATIVE VOICE
CONDUCTOR, effected by the Messrs. S. and B.
SOI.OMONS, OPTICIANS and AURISTSto the ROYAL
FAMILY, 39, ALBEMARLE-STREET, PICCADILLY,
by which thousands of deaf persons have keen 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 te 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 lin ivvn 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 " Dictionary of Arts and Sciences" of Andrew Ure,
111. D., F. R S., &c., &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 ; tha workmen, too, are subject to nervous tremors in
their wrists, arms, &c. ; they encounter 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. tire's statements are further confirmed by Sir
D. Brewster and Pliny, as also by Parks and Herns, 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
had at their establishment 3. 39, Albemarle-street (opposite the
York Hotel), and 76, King William-street, Bank.

MOST IMPORTANT
SCIENC DI
ESCOVERY IN MEDICAL
Vincet veritas et prevalebit."
FEAVER'S INFALLIBLE EMBROCA-
TION for GOUT, RHEUMATISM, RHEUMA-
TIC GOUT, TIC DOULEROUX, LUMBAGO, SCIA-
TICA, RHEUMATIC FEVER, QUINSEY, &e., is now
for the first time introduced to the notice of the pullia; al-

though in the present age of imposture it is difficult to put for-
ward a truth, however important, that shall not be liable to be
confounded with the daily empirical puffs that are obtruded on
the publics eye. This consideration has for a long tine deterred
the proprietor of Feaver's Embrocation from advertising it.
Foaling, however, a thorough conviction of the incalculable be-
nefits it will confer on mankind, he conscientiously believes
that, by withholding it longer, he would be wanting in the com-
mon feelings of humanity towards his fellow-creatures, and of
duty towards himself. He, therefore, no longer hesitates to
adept this mode of making this wonderful remedy generally
known, that the afflicted may have an opportunity of enjoying
the blessings it offers them. This specific was revealed to the
proprietor's father twelve years ago, who then cured him-
self
of a very obstinate case of inflammatory gout of thirty
years' standing, and although on that occasion he hael been
confined to his bed-room for two months, he was enabled to
walk two miles within six hours after the application. Since
that period thousands, from the noble to the peasant, have been
cured by it. In short, it is no exaggeration to assert that it has
never been known to fail in effecting a cure, where the proprie-
tor's instructions have been attended to. Its extraordinary
efficacy has been for years tested by several medical gentlemen
of distinguished eminence, who declare it to be the greatest
discovery every made in medical science. The superiority it
possesses over every other remedy consists in its being an in-
noxious vegetable compound, in the perfect security with
which it may be used (outwardly) by the most afflicted and
timid patient, and in the certainty of its being a sound, safe,
and radical exterminator of the above-named maladies in all
their terrible and agonizing forms. Original testimonials in
confirmation are in the hands of the Proprietor, Nos. 2 and 3,
Friday-street, for the inspection of those who may wish to
satisfy themselves on the subject.
To be had of Mr. Feaver, Friday-street, Cheapside; Bar-
clay aid Sons, Farringdon-street ; Newbury and Sons, St.
Paul's; Sutton aid Co., Bow Churchyard; Willoughby and
Co., Biskopsgate-street ; Sanger, Oxford-street; and of most
of the respectable Chealiste and Medicine Venders in town
and country. Ii bottles, at 4s. 6d., tis. 6d., Ifs., 155., and
30s. The label bears the autograph signature of the proprietor.
N.B.—The public are requested to refer to the London
morning papers, front the 6th to the 12th of July last, for a let-
ter from Thi,mas Sc .field, F.sq., relating the extraorlim:q
eure created on him by the use of this embrocation.
