July 7th at 1º P.m. put in water in dark, Beans, [sketch] Candytuft — Anothera & Potato The shoots were put in inclined position & next day after 19º all had bent up— Moved these plants half round so that the now upturned tips pointed downwards & in dark after 11º. 15' reversed movement & turned up — again a i e reversed their curvature— Mem. this is movement not growth — Fuchsia Lavender & Cherry turned once fully up — Syringa & Marmorata did not turn once up— — I now find after several

trials that young, (oldish much slower) stolons, ultimate joint, bend downwards, even when placed vertically so that I think gravity cannot come into play — take about 36º or 48º to bend much in dark
Observations repeated on Stolons of Strawberry & I have no doubt that in above time they bend down, when placed almost vertically more than can be accounted for by Gravity— Two out of 4 shoots of summer shoots of Bramble bent up in 48º.— Again 2 turned slightly upwards. Tamus communis in 26º in dark doubled 2 internodes back & began to wind on self — — this not revolving must not have affected the mere revolving coiled
