Silver crystal surfaces which had been prepared by either electrolytic etching or electrolytic polishing were studied by means of the electron diffraction reflection technique. It was found that fine structure effects, in the form of split spots or streaks through spots, gave information concerning the topographies of the various surfaces of the crystals. The fine structure effects showed certain asymmetries which do not immediately follow from the Laue diffraction theory The possible causes of these asymmetries are discussed, and it is concluded that they were probably due to distortion of the silver crystals, but that some might have also been due to refraction effects.
