11th November Down

12° 50' Turpentine almost dead at 9° P.m.

12th 9° Am killed

11th

1° 10 bit of paper on 2 or 3 Hairs / at 9° became vertical

12th 9° 30 rolled into centre ie 20°

2° 30' Thread Cotton thread on young leaf, on straight Hairs by footstalk. — (2 bits on large leaf 12th both moved but not to centre)

4° ie 1° 30' considerably inflected 9° carried to centre ie in 4° 30'

(Put another bit of thread in on rt side of footstalk at 4° 12th 9° 30' 5° 25' in centre

No other Hair moved.—

(Nov 20 in 2 other cases difference of colour plain on 2 sides of Hairs.)

Shorter thread = 15/500 of an inch = 30/1000 = 3/100 —.03

Longer piece 19/500 of an inch.

Finest cotton 12th 10° A.m (ie 22°)

Shorter thread — Hair much curved — red much broken up whole length except colourless basal part — Head granular, but not more Red matter undergoing undergoes change of form. Convex side darker pink [sketch] — darker.

[72v]

Blotting paper 21/500 long = 42/1000 long

Rested on 3 hairs & caused all to curve into centre

Nov 12th → These 2 moved out of their rank & approached 1/2 way to centre.

11° 5 Thin [illeg] of Emma's Hair Red 1 on 2 quite straight Hairs in 12° 15' strongly curved i.e. in 1°. 10'

1 piece 9 1/2 /500 = 19/1000 of an inch long convex side pinker. No more change in red matter & no more spheres under those in many other hairs — Probably leaf has acted before Yes it is not a young leaf.—

2d piece barely 9/500 = 18/1000 all the Hair with few spheres under Heads— Pink plainer on one side than other in the incurved Hair.

I am certain I did not touch Hair gland as I put on under lens with damp needle moisten with water

[73]

Longer thread red broken almost to base.— Head a little more broken — / 3 other Hairs not broken, on one a trace of breaking / 20 other Heads Hairs not broken in few just a trace close to Head— Heads themselves all with orbicular collection of granules. I have now examined all Hairs, in most a little breaking up in the hairs for once or twice or even thrice length of Heads Now Now it is 10° 15' there are few small spheres. — The two curved Hairs all broken up into ovals threads & minute spheres wholly wholly different appearance!!!

It is probably due to incipient closing action of all Hairs.

[in margin:] This was a young leaf & therefore not likely to have Head broken up beneath

A third on the old leaf bit of thread was only 10/500 = 20/1000 of inch long curved; plenty plenty of breaking up but not so much as in former case, but caused the Hair of to be understandably much curved. —

Hair shows action cannot be due to absorption of secretion: — (Not shutting off the light—)

[73v]

Hair sent to be weighed 6 inches

Blotting Paper 11

Thread 30

It is extraordinary that slips of glass over cut-off Hair did not make red segregate — Either being cut off or water checks this action—

The Hair not by any means minims action.—
