Abstract
The Knorr-Albers microphotometer has been modified to permit the application of the trapezoidal rule to the measurement of the true areas of photographically recorded figures of irregular shape. These modifications include a vertical plate-elevating mechanism and a timer controlled by a cam and roller microswitch.Keywords
