    Figure ii—(Continued). Curve D: Color Naming. (Subjects Fi, F2, F3 and F4.) Abscissas indicate successive days; ordinates indicate speed of performance on successive days, in terms of per cent of the initial day. Curve E: Opposites. (Subjects Fi, F2, F3 and F4.) Abscissas indi- cate successive days; ordinates indicate speed of performance on suc- cessive days, in terms of per cent of the initial day. Curve F: Fatiguability. Tapping with Key. (Subjects F2 and F3.) Abscissas indicate successive days; ordinates indicate degree of fatigue on successive days in terms of the index of fatigue. ^--a' Figure 12 Curve G: Composite curve composed of Curves A, B, C, D, E and F. Shovi^s total performance of Fi, F2, F3, and F4; includes ten cycles of 28 days each, and six various kinds of performance. Composed for purposes of comparison with Van Ott's Curve {Curve V), and with the composite curve of Mi and M2 {Curve G'). Curve G': Composite curve showing the total performance of Mi and M2; includes five pseudo-cycles of 28 days each, and six various kinds of performance. Abscissas indicate successive days; ordinates indicate performance in terms of per cent of the initial day. Thus Curve G and Curve G' may be and are platted on the same base and scale. Curve V: Van Ott's Curve of the monthly cycle, showing the com- bined behavior of blood pressure, temperature, pulse, caloric radiation, vital capacity, and reflex action.
