ROYAL FAMILY, 39, ALBEMARLE-STREET, PICCADILLY, by which thousands 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 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 newlyinvented 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 n ith great distinctness ; by the use of which both the sight and hearing become much improved. The Messrs. S. and B. SOLOMON'S disclaim all connexion with persons of the sine name, and the sale of amber spectacles ; the pernicious use of amber spectacles being now well kri iwn to the public, and the 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 ether than those of amber ; the history and- destructive use of that material for Spectacles to imperfect vision is fully and most satisfactorily explained by the undermentioned scientific authority : From the " Dictionary of Arts and Sciences" of Andrew Ure, " Amber is an indurated vegetable juice, and not produced by the laws of crystallisation, but by the same causes which M.D., F.R.S, &c., &c• 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 fragments ; the workmen, too, are subjectter great danger by handling to nervous tremors in their wrists, arms, &c. ; they encoun such dreadful excited eleetrics ; amber grows with lime, and is apt to take tire, 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 Heins, on Chemistry. The destructive effects of such a material for spectacles, 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 superior, 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 only to be had at their establishments, 39, Albemarle-street (opposite the York Hotel), and 76, King William-street, Bank.
