title: A simple aid in the evaluation of glass knives.
abstract: This report describes a compact, portable, self-contained light-box for the qualitative inspection of glass knives under a microscope. It obviates the need for elaborate illumination and viewing facilities in the microtomy laboratory when the ultramicrotome is not itself equipped with knife-inspection devices.
