Feb. 19th. to morning of 24th 8º a.m— Dionæa

One of the leaves (both very young ones) formerly observed Sept 24' (see date on Diagram) with triangle of paper on a spike— beginning of December — from Sept reobserved under Compound M. — A long glass filament fixed to one Spike.— Petiole at first not secured. — The filament in nocturnal movement, best described by an endless number of little jerks or twitches (— moved 10/500 in 30') but with preponderance in one direction giving impression of effort

At 10º 25' cemented with shell-lac narrow end of petiole above foliaceous part to square summit of little stick driven into pot— so close that nothing but blades cd move. — This was not done before & perhaps vitiates pure observation: consider notes. —

After being thus fixed continued oscillating nearly 1/500

Temp only 53º F. some continued opening all rest of afternoon viz from 2º, 12' P.m. to 10º 45'— during which time 8/500 ie about 1/500 every hour. — continued to move in same direction all night & next morning early, still oscillating. The movements all the prior time so much less than when petiole was free, that part of movement no doubt in Petiole.

Twitching while closing & when observed see March 6th note about same effects of worth

Do not speak of making little ellipses but of movements in all directions—

Feb. 20' 8º 12' gave lobes a stream of warm turbid infusion of raw meat, & lobes instantly closed somewhat about 1/2 as much as cd close. This proves that leaf by no means torpid, & this may account for circumnutation of petiole. At 8º 50' 17' adjusted the scale & after 33' had moved moved & closed 15/500 — In middle of day closed slower viz about 1/500 each hour

Feb 21'— in morning was closing more quickly, always twitching, fully 1/1000 — & certainly moves in all directions, though preponderately in one—

In afternoon marginal spikes partly intercrossed—

The closed blades are also rising.

At 3º P.m more infusion

Feb 22d continued so to act— The distal part of lobes never closed completely

Feb. 23d & morning of 25' still twitching & lobes falling a little— so always in slight movement even after lobes closed with infusion & no doubt digesting.

26th I found whole of the 2 lobes completely closed
