June 12. (64) Fumaria officinalis —

It is surprising that so lowly a plant shd climb. It does this by lateral & main peduncles of compound leaves — even the terminal central main peduncle is sensitive, though flattened like a leaf.—

Even a thin loose blade of willow grass will excite movement.—

June 14' Rubbed 3 or 4 time lightly several peduncles little or no effect — A 5 inch straw did not act in 12° but in 20° had produced decided effect, but never clasped it very closely.

A stick out in fork, in 7° a plain & decided movement — in 9° almost curled round — & then stick taken away

Light has much effect in drawing plant to window.

Leaf observed holds itself nearly upright aspect of course like Tendril of Cobæa & when old sinks down to gentler inclination with stem

Course extraordinarily Crooked — {

June 15 — little peg to central internode at 8° A.m.

This moved all day in a considerable degree, making a zig-zag course (passing into an irregular spire by lines crossing each other) obliquely to window — It made during day 12° about a figure which perhaps represented about 4 ellipses

The line of A leaf of good size second from summit partook of the movement, but in an exaggerated degree, & harmoniously, for the central petiole curved itself, as it swung from side to side— It was impossible to observe rate of movement, as the figure traced on the glass was so irregular; but one figure of 8 was performed in 2°. 20'— Movements certainly rapid. The movement of the leaf during 12° represented about 4 or 5 Ellipses, which d were directed in widely different direction & at ∠' to each other.

Jun 16th.— Leaf (shoot only pretty well secured) moved in zig-zag in morning to light & then in very irregular small ellipses The zig-zag is broken ellipse owing to movement to light.—

17th. I am now certain from painted lines, that petiole curves from side to side.— Leaf with axis securely tied, moved in small irregular zig-zag to light which I believe represents ellipses— Certainly movement small, but I have no doubt some real movement in leaf-stalks.—

Jun 18' I rubbed 5 or 6 times with light twig several petioles, they bent in about 1°. 15'. Bignonia
