The curves of the posteriorfeet are below those of the corresponding anterior. The ascending part of each curve correspondsto a contact ; the descending part to an elevation. The length of the lines of the notation, situated belowthe tracing, indicates the duration of the contact. The interval between two while lines represents theduration of the elevation of a right member ; the interval between two gray lines represents the durationof the elevation of a left member. number 1, the figure will be divided into successive spaces, in which will befound in contact (with the soil) sometimes two membe
