This paper deals with a new kind of electron microscopy in which the specimen constitutes an electron mirror. The low velocity of the electrons in front of this mirror‐specimen enables pictorial representations of potential distributions on surfaces. A resolving power comparable to that of the light microscope has been obtained. Sample micrographs depicting surface reliefs, potential distributions on surfaces, and the distribution of electrical conductivity are shown. The peculiar kind of image formation is briefly discussed and reference is made to the potentialities of such a research tool for surface physics and metallurgy.

The referee of this paper has informed the author that a paper is presently in print under the title of “Ein auflichtelektronen‐mikroskop” by G. Bartz, G. Weissenberg, and D. Wiskott reporting substantially the same results. This paper will appear as a part of the Proceedings of the International Conference on Electron Microscopy in London.
The referee also stated that V. S. Vavilov deals with a related subject in the
