Fig. 130.—The Step: Right Diagonal Pressure.
Thus, we find at the start a right lateral pressure ([Fig. 129]), next a right diagonal ([Fig. 130]), then a left lateral; finally, a left diagonal pressure. It is thus that the initial letters L, D, L′, D′ further indicate the notations represented in [Fig. 128].
