1878 June 5th to morning of 7th

Verbena, herbaceous Scarlet-flowered

Circumnutated of stem

Though I had observed Lemon-scented bush, I thought thought Plant 8 inches high it worth while to observe a hebacs herbaceous species, which had been laid flat for observing observing apogetrops & the terminal, 1 1/2 inch of shoot had bent up rectangularly.

In this case traced on vertical glass, kept in darkness.

Tracing of the bead magnified only 9 times. Of course lateral lateral movement ie in plane of glass chiefly shown, but the rising & falling of the beads shows that there was backward & forward movement.

Tracing from 5. 30' P.m on 5th to 11° a.m on 7th

[Calculation not transcribed]

There can be no doubt about circumnutation.—

Between 6° 50' a.m & 11° P.m. (ie on 6th, moved 4 times to right & 4 times to left — ie. in 16° — ie an ellipse in every 4°. —

(A shoot 8 inches in length had been laid horizontally & the for the sake of observing its apogeotropism & the terminal portion had gone up quite vertically upwards for a length of 1 1/2  in a glass filament with a bead at the end was fixed vertically to the tips, & its circumnutation circumnutation traced on vertical glass, during 41° 30'.

Under this circumnutation the lateral movements are chiefly shown, but the rising & falling of the bead as the line from side to side are not on the same level, the shoot must have moved largely to or fro in a plane at rit angle to that of the lateral movement, or circumnutation on the 6th the shoot moved in the course of 15° 16° four times to the right & 4 times to the left, repeating partly & then apparently repeat the portion of for ellipses on a so that each was completed in 4 hours.—
