Pinus pinaster circumnutation of young leaf July 31 to morning of Aug. 4th

5 or 6 sets of lettering

Same scale: the 2 figures on same Block; a little closer: the 2 dots, both marked "7˚ a.m 2d" should stand on exactly same level, & perhaps the one set of lettering with arrows would serve for both (at 7˚ a.m 2d →.)

Pinus pinaster: circumnutation of young leaf, traced on vertical on the two figures given from 11˚45 a.m July 31' to 8 20 a.m Aug. 4th ─ Apex of leaf 14 1/2 inches from the vertical glass so movements much magnified.

on an average 5.23 seeds per capsule; the remaining 56 capsules having been spontaneously self-fertilised. Of the 84 capsules on the self-fertilised plants, all the product of renewed self-fertilisation, fifty-five (which were alone examined) contained on an average 4.85 seeds per capsule. Therefore the cross-fertilised capsules, compared with the self-fertilised capsules, yielded seeds in the proportion of 100 to 93. The crossed seeds were also relatively heavier than the self-fertilised seeds.) Combining the above data (i.e., number of capsules and average number of contained seeds contents ), the crossed plants compared with the self-fertilised, yielded seeds in the ratio of 100 to 64.

These crossed plants (being covered by a net) produced, as already stated, 56 spontaneously self-fertilised capsules, (part of the above 121 capsules) and the self-fertilised plants produced 29 such capsules. The former of these contained on an average in comparison with the latter seeds in the proportion of 100 to 99.

In Pot III., on the opposite sides of which a large number of crossed and self-fertilised seeds,
