Summary

Half circle to light (from 6° 57 a.m to 12° 23 P.m) took 5°. 26.

─ from light (from 12° 23' to 2° 45' P.m) took 2°. 22' / 3.° 04

Therefore moved twice as quick slow to light than from light to dark

Half-circle to light (from 2° 45' 7° P.m) took 4°15'

─ from light (from 7° to about 10° P.m) (but then this was all in dark) took 3° / 1. 15

Therefore moved slower to dim afternoon light than from light when it was dark.

A tendency to the separation of the sexes in the cultivated strawberry in seems to be much more strongly marked & has been more alluded to in the U. States than in Europe; & this fact is interesting as showing the direct effect of the conditions of life action of climate on the reproductive organs. In the best account which I have seen * (*Mr. Leonard Wray in Gard: Chron: 1861 p 716) D it is stated that many of the varieties there in the U. States consist of three forms, namely females, which produce a heavy crop of fruit, ─ of hermaphrodites, which "seldom produce other than a very scanty crop of inferior

[Forms of flowers, pp. 292-3: "A conversion of this kind is at least possible, although it is the reverse of that which appears actually to have occurred with some Rubiaceous genera and Ægiphila; for with these plants the short-styled form has become the male, and the long-styled the female. It is, however, a more simple view that sufficient time has not elapsed for the reduction of the pistil in the male and hermaphrodite flowers of our Euonymus; though this view does not account for the pistils in the polleniferous flowers being sometimes longer than those in the female flowers.
