existence of statistical variation of sensitivity among silver halide grains is discussed. For photolysis in a homogeneous system, a mathematical expression is developed relative to the density-exposure function and has the formula D' = -In [ e-L',n + (I \_ 'z-D,+ &+"J]+ 1'1 le relation of statistic

A statistical theory is given of the connection of the graininess of the photographic negative and the flu ctuations of the density measured with an arrangement containing a galvanometer. This theory is applie d to the microphotometer and the graininess-m eter.
