SPECTACLES.—WM. ACKLAND applies his medical knowledge as a Licentiate of the Apothecaries' Company, London, his theory as a Mathematician, and his practice as a Working Optician, aided by Smee's Optometer, in the selection of spectacles suitable to every derangement of vision, so as to preserve the sight to extreme old age.
ACHROMATIC TELESCOPES, with the New Vetzlar Eye-pieces, as exhibited at the Academy of Sciences in Paris. The Lenses of these Eye-pieces are so constructed that the rays of light fall nearly perpendicular to the surface of the various lenses, by which the aberration is completely removed; and a telescope so fitted gives one-third more magnifying power and light than could be obtained by the old Eye-pieces. Prices of the various sizes on application to
