For practical educational purposes there are four types of badposture that need tobe considered.^ Thecommonest of these iscalled the fatigue posi-tion, because, thoughunfortunately the ha-bitual carriage of somepeople, it is the col-lapsed or relaxed posi-tion that any one isliable to assume tem-porarily when the fatigue posi-tion (Fig. 2) the neckand head droop for-ward, and the upperpart of the trunk sinksbackward, so that astraight line indicatingthe axis of the head,neck, and upper backslopes downward and backward to the region of the shouldersinstead of being vertical; the axis of the lower trunk joinsthis upper line at an angle and slopes in the opposite direc-tion— downward and forward to the hips; a line from this 1 See Appendix, Note Figs. 3-4. — The vertical line test made by holding awindow pole beside a pupil: poor posture and itscorrection.

There are thus, in this fatigueposition, three distinct lines indicating the axes of the threemain divisions of the body, instead of onecontinuous, vertical line as in the perfectlyerect standing position. The faulty position and its correction are com-pared with a vertical line in Figs. 3 and 4. The second of the four types of bad posture is one in which the lower part of the back is straight. The natural inward curve of the spine at the small of the back is obliterated, and the back is straight or even bowed outward at this \\ 1 point (Figs. 5,6).
