Planimetry, measurement of areas of plane figures, very frequently used in medical-physiological research works, primarily with respect to areas of curves recorded on a kymograph. Such measurement can be performed either with the help of auxiliary grids placed over the figure, or by means of mechanical measuring instruments called planimeters. ^Measurement with the help of grids. The most primitive method of measuring the area of a figure with irregular contours consists in placing a glass with an engraved or phonographically reproduced millimeter grid over the drawing of this figure (one can make it oneself by photographing a sheet of millimeter paper in natural size on a large photoplate). Then all millimeter
