Abstract
Eyepiece Micrometer. DR. METZ, one of the researchers employed in the Leitz optical factory at Wetzlar, has recently described1 a micrometer for use with the microscope which, if we are not mistaken, will rapidly replace all others, including the expensive filar micrometer where a mechanical stage is available. The root idea is that the scale used is such that microns can at once be read off without greatly changing the tube-length, or considering the micrometer value of the objective employed, and therefore dispensing with the arithmetic for which this is a necessary datum.
