Abstract
WE have found it instructive to reverse the normal microscope procedure in the examination of nuclear emulsions ; invert the plate, feed light in through the cover slip, and observe through the backing plate. With high magnification, normal objectives and ordinary glass-backed gelatine, this is not possible ; but it may be done by using a reflecting microscope1. In this way, with oil immersion, we observed several multiple stars, and found heavy fragments which were not visible by the normal mode of examination because they were obscured by the central body of the star. In some doubtful cases, this mode of examination proved decisive in the interpretation of the event.
