III. 525 minutes.⁠12 tests.⁠The learning at the time A, the relearning at the time C. The different influence of the two times of day is calculated as follows: eight series of 13 syllables each required, with 38 tests at time C, 1173 seconds (P.E._m=10); similar series with 92 tests at time A required 1027 seconds (P.E._m=8). The first number is approximately 12 per cent. of its own value larger than the second; therefore I have subtracted that much from the numerical values found for the time C.

IV. One day.⁠26 tests, of which 10 were at time A, 8 at time B (here as everywhere consisting of only 6 series each), 8 at time C.
