Sept. 2d. 1878

Celery— seedlings Light Painted Useless

Painted with thick Indian upper half of Hypocotyl & lower half of 2 others — in blackened box before S.W window

Exposed at— 9° 10 Examined at. 5 20'

All 4 curved immensely to light.; the 2 with bases painted not so much as the 2 others because the basal part not so much curved, yet basal part is curved though I do not believe it could have received any light:

Perhaps if I had looked earlier upper painted half, wd at first have been curved— now they are stretched horizontally.

(Exposed to apo-geotropism at 5° 30' 11° 15 a.m

3d. — All curved pretty well apogeotropically; but those with painted basal halves, less curved in lower part, I suppose owing to mechanical resistance.
