Tomato

(Solanum lycopersicum)

(Used)

Oct 19th Secured stem & fastened bristle longitudinally to one cot. & then covered up pot in brown-paper cot. First dot at 9° 15' but by 1° no vestige of movement. Thus it is clear that without excitement of light, Cots. do not move.

(10° 30' P.m The younger plants now have leaflets almost closed.

(Oct. 20 I fastened bristles to 1 cot. on 2 plants & placed them facing light, the stems having been secured, but tops of stems grew rapidly & the 2 cots. bowed towards light & quite spoiled trial. The Cots. were also I think overpowered by weight of Bristles. All failed.)

Oct 21. In the morning the plantlets bent at ∠ to light in study. At 1° put them in window of dining room in reversed position & they were at 5° bent at right angle in opposite direction, so that they had moved during day through angle of 180°. +9° At night the Cots. did not go to sleep was this result of so much movement?
