Extract

Previous communications have established the formula for the Bat curve as - Dp.k + n.d = tk · 2n, where k is a constant Dp-age, d is a constant difference of Dp-age, tk is the time value in m.y. at the Dp-age k. For Compositæ (Small, 1937, Q.E. II) and apparently also for the Grasises (Small, 1937, Q.E. III) k = 0·6, d = 0·9, tk = 1·09375 m.y.
