Abstract
THE feasibility of electron microscopic autoradiography was suggested to us by the report of O'Brien and George1. We have tried a similar technique with tritiated thymidine in tissue culture and have found that recognition of reacted grains in the nuclear track emulsion may be greatly facilitated by their distinctive filamentous appearance, and that the intensity of labelling may be increased by exposing the grids in a strong magnetic field.
