The internal surfaces, i.e., g of flint lens a and y of crown lens are by preference
identical and cemented, and such that for the above focal length and qualities of
glass employed combination A may be achromatic or actinic. The diameter of the

... reflection at the contact surfaces. The flint lens occupies the exterior position in
each combination. It is coucavo-convex, convex side external. The crown lens is
a meniscus, the convex side of the same radius of curvature as the flint lens.

These defects the author proposes wholly to obviate, by substituting for the
Huyghenian eye-pieces, single achromatic lenses of corresponding magnifying
power; consisting of the well-known combination of the crown-lens, and its
correcting ...
