about one-tenth of an inch, each square made of fine wire, or lines
drawn strongly on glass in a circle of one inch in diameter, and placed
these in the compound body of a microscope or telescope, in the focus of
the glasses next to the eye. And having a copper-plate lattice of
squares disposed into a circle, and to any size as may be wanted, the
observer or artist may then with great facility make an exact drawing on
the paper of the object observed. The same contrivance is applicable to
the solar microscope. This he called the GRAPHICAL MICROSCOPE OR
PERSPECTIVE.
Page 127, line 24--Any pocket telescope, the drawers of which are made
to allow of a further extension than usual, may be used as a compound
microscope for examining birds or insects alive, in a garden on the
flowers, shrubberies, &c. from a window near to the objects. There are
few pocket achromatic telescopes or perspectives, but what will define
and magnify objects from about six feet to any distance from the
instrument. The magnifying power is inversely as the distance of the
object from the telescope, and, consequently variable in an infinite
degree; on which account Mr. Martin named it the POLYDYNAMIC
MICROSCOPE.
