The possibility of constructing an instrument which would automatically inspect particle tracks in nuclear emulsions is discussed. An instrument using two photomultipliers added to a type MB-8 microscope is shown. The trace is projected on the cathode of one of the photomultipliers and the background on the other. A microammeter determines the track-background difference. It was found that for work with relativistic particles it is necessary either to increase the density and size of the grains or to introduce summation over several inspection fields. But experiments have shown that it is possible to obtain a stable signal source for automatic inspection of tracks. (J.S.R.)
