Nov. 29' & 30'

Phalaris Asparagus Canariensis. Canary grass— 1877

(The tip was whitened with chalk & black dot on cards beneath.)

Nov. 30th All following observations made in HotHouse plants protected on all sides so that light came in only from vertically above — (Asparagus) Traced on Horizontal glass.

Diagram I. plant only. 45 of inch high, consisting of single internode with little bud on top; glass 14 1/2 inches from mark below & at this distance difficult to trace very accurately. Tracing magnified 35 3/10 say 35 times times There can be no doubt about nutation on small scale; three ellipses made between 8° 30 a.m & 8° 15' P.m.

Diagram II. This plant only .3 of inch tall— moved zig-zag till 12° 52' & then returned on nearly same line making a great bend to one side late in afternoon. (Used)

Nov. 29 Diagram III. This plant was 1.1 high, consisting of 3 internodes, besides bud on summit no Tracing magnified 11 6/10 say 12 times. figure probably represent 3 ellipses between 8° 10' & 8. 10 P.m. —

Diagram IV. This plant of intermediate high was 2 1 3/4 inches high & consisted of 5 3 internodes beside bud & Tracing magnified 8 7/8 say 9 times. & therefore more magnified

Diagram V. This plant was 2 inches high & consisted on 5 internodes bends terminal bud Tracing magnified 5 6/10 times (say 6 times)

There can be no doubt about nutation; & in fact with the 2 latter taller plants the tip cd be seen at intervals bending to the several to points of the compass like a climbing plant.— I am nearly sure that there is

(Asparagus)

a climbing Asparagus. — (It shd be observed that by accident I left curtain on side on which most light entered unsuspended for 50' ie. between 12° 53' & 2° 3 & this probably [illeg] stem little to light & afterwards by reaction from it; this latter movement being much greater is very curious. I doubt whether worth mentioning.)

[insertion:] I think worth giving as showing effect of short exposure to not bright light on one side light coming from orchard all the time.—

It is very suspicious that the longer axes of movement is in III. IV & V to & from the light, I think the 50' exposure must have had an Effect— I might measure the transverse distances in diagrams.—)
