TRUSLOW Three types of posture, varying according to differing anteroposterior relationships, are here named and discussed: (1) "kangaroo" type; (2) normal or neutral type, and (3) "gorilla" type. Distinguishing features of the normal type are: (1) the line of gravity of the body passes through important pivotal points; (2) the pelvis is balanced in equilibrium on the heads of the femora, its position being indicated by the angle which the plane of its inlet makes with the horizon; (3) this relation of important pivotal points with the line of gravity and this balance of the pelvis insure an easy balance of all superimposed structures of the body, including the spine in its physiologic curves; (4) the rear perpendicular touches two points, the shoulders and the buttocks (Fig. 1). The carefully balanced segments of the body
