applied it to the telescope. Campani applied it to the
microscope, whence it is sometimes called {Campani's
eyepiece}.

{Positive eyepiece}, an eyepiece consisting of two
plano-convex lenses placed with their curved surfaces
toward each other, and separated by a distance somewhat
less than the focal distance of the one nearest eye, the
image of the object viewed being beyond both lenses; --

eyepiece}.

{terrestrial}, or {Erecting eyepiece}, an eyepiece used in
telescopes for viewing terrestrial objects, consisting of

the image of the object viewed in an erect position.
