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 give one-third more magnifying power and light than
could be obtained by the old Eye-pieces. Prices of the various sizes on
application to
WM. ACKLAND, Optician, 93. Hatton Garden, London.
