Rhythmic shift of positions of single cones based upon serial tangential sections. Group C. Note in Figure 1 that only three of the points for group A lie above those of group E, while in Figure 2, 7 of the points for group A lie above those of group E. Tables I and II summarize the combined statistical data for groups A, E and F. As shown by the probability values derived from Student's t-test, there were significant differences between the adjacent points from 2100 hr. to 2200 hr., 2300 hr. to 2400 hr., 0200 hr. to 0300 hr., and 0400 hr. to 0500 hr. The significant differences practically alternated with insignificant differences. The data for group A show that both single and double cones continued to contract beyond the time of expected sunrise. The RP values reached a minimum at 0800 hr. and fluctuated around that value through the remainder of the day. Both single and double cones showed a persistent photomechanical rhythm in constant darkness. This was first demonstrated by group C (Figs. 4 and 5) in which the results were based upon serial tangential sections. Note that the TABLE 111 Mean RP values of double cones through 65 hours in darkness, based upon serial tangential sections. The eye at 0 hr. was light-adapted.
