Abstract

Nobert's Test Plate, as an instrument for trial, is admirably
adapted for comparing the quality of object-glasses, supplied
by different makers,and every microscopist who possesses
a first-class instrument naturally desires to know what it is
capable of doing; for when the power and quality of his lenses
are known to him, he is convinced it would be only a waste of
time to try them further.One of the most important tests that the properties of a
microscope can be tried by is to clearly "resolve" the very
fine lines of the frustules of the Diatomaceae. The value of
minute Diatomaceae, is, in their surface markings, which are
admirable test objects for the higher power of the microscope.
