Maize— Radicle, nutation of

Took 2 seeds of which radicles just protruded barely 1/20' of inch & fixed glass-filament to them, whilst lying upside down on damp sand & traced movement on Hor. glass in darkness. 24 [+] 12 [+] 2 [=] 38

(1) moved in very slightly zig-zag course in one direction from 8° 25' to 6° 6' P.m. by which time it had begun to returned in nearly parallel course. It continued in same course all that night & on 15th & morning of 16th, but then during 15 & 16 went in very complex zig-zag course, but from examining it afterwards it seems shrinking & drying, though occasionally watered, so that later observations cannot be trusted in this or next case.—

(2) The second seed, from the first went in zig-zag course, (which after first day became excessively complex & due no doubt to drying). There was one prevalent direction in this & last case, due no doubt to geotropism.—

Probably nutates whilst hypogean.—
