Abstract
THE unit of the photographic plate is the single grain of silver salt as it exists in the sensitive film. It is natural, therefore, that after many years and much labour had been devoted to the properties of sensitive films as films, attention should be turned to the unit. A great deal of work has already been done in this direction, but many problems, some of which seem to be of an elementary character, remain to be solved.
