Important for theory

Feb. 1 & 2. Phaslitis nil 3 seedlings exposed to strictly lateral light & on the 3d exposed to lateral light & to light from above & could not see that Cots, bent in any way to light, hypocotyls secured. One of seedlings was placed exactly with 2 Cots in line to light. & further Cot. did not rise as I have often seen such Cots do.—

This latter seedling had filament fixed & was observed during the 3 days. Fell on 1' from 8° 45' to 10° 15, but this may have been drooping for want of water— then rose to 7° 20' P.m & fell afterward & during night.— Next morning (2d) after 7° 15' rose till about 2° P.m & then remained almost on same spot 9° & then fell an atom to 10. 45' P.m — fell another atom during night.— Apparently rigid from having only lateral light— Top then uncovered, & now (3d) fell considerably till 12° 50 & then rose to 4° & fell a little to 5°, when glass was accidentally smashed— Probably first days observations may be trusted & this shows that rises during day & falls during night.— The second day also shows rise during days & then become rigid— On third day more disturbed, for fell instead of rising till 12° 50 & only then begin rising till 4°. P.m.

(after reading over my M.S. description p. 54 A

I suspect great variability in periods of movement, & that commonly that the diurnal fall is continued till the early part of the night. Can hardly be considered as a real objection to the rule.
