Machontia (?) surface of Pot— in damp-place coated with [fronds] (?) bearing spores — so not young.

(In intervals of observation covered by Bell-glass.)

Selected a frond which transversely was .4 of inch in length & at right angle .3 but laterally united to another frond fixed a filament (on Oct 27') .75 inch of length at right angles to transverse diameter.

The vertical glass plate was 8.5 distance, & dot behind at such a distance that figure traced on Oct 27th magnified about 56 40 times.

This frond was originally inclined considerably upwards, having been placed before

[insertion:] Of course the filament increased the movement, considerably, & the movement of the frond end was greatly magnified

a N. E window on Oct 19th at 9° 15' a.m & it continued to sink till evening of Oct 24th, when filament fell off. (See tracing) As the frond kept on sinking day & night probably not due to apheliotropism— either epinasty or geotropism.— As course was so zig-zag with some circumnutation loops formed, I felt course wd circumnutate, as soon as had sunk to its proper bearing, & it sunk, but little on the 24th

On next morning Oct 25th 27' 8° 45' 9° am new tracing began. B (greatly magnified —) given & continued during 2 days.— See fig B. Here there can be no

(Although this plant was not young, for the fronds were producing gemmæ, yet as the movements of a few other cryptogamic plants have here been given, those f of the present one may also be here described.)

doubt that the frond was circumnutating. The fact was so surprisinged, so much that on following day Oct 27' we made a fresh tracing. Fig C. & again found the plant circumnutating.

On the next day Oct 28 filament with 2 little triangles, but this did not magnify movement sufficiently yet we saw that it was moving. On the 29th we recovered the one from plant, but rather less magnified but now the frond moved over a very small space.
