Feb. 16 80/ Alabama Cotton at 4º 40' P.m. Cots. still Horizontal — Darkened 8º 30' not asleep — 10º 30' no depression

18º 10º 30' P.m not in the least asleep.

(20th 8º 25' P.m Cots. Horizontal (specially finest seedling) turned pots upside down 10º 20' P.m. cotyledons in their reversed position have certainly sunk down, so that weight does produce some effect

(Feb. 27th 10º. P.m Both lots with cots: flabby & depressed, but one can recognise at once when Cots. are flabby from being too dry)

Feb. 16 (80). Sea-isld 3 Plants Cotton at 4º 40' P.m Cots still horizontal darkened. —

8º 30' a little depressed 10º 30' a trace depressed & Cots rather folded — a slight plumule

18' at 8º 40' cots not a sleep, but rather folded & apparently rather flabby, so turned pots upside down & by 10º30' P.m. Cots sloped downwards in this inverted position & this shows that weight had acted on them; but it is possible that they were too dry & flabby.—

By 7º a.m 18th mid-ribs had risen showing that tension had increased during night on [2 words illeg], but still flabby for on reversing pot, they sank down

20th 8º 25' P.m Cots almost horizontal — turned pot upside down— 10º 20' P.m Weight of Cots has certainly depressed them in their [illeg] position

[18v]

Add after G. Herbaceum that these 3 Kind all behaved in same manner—

There is goodish sentence about effects of weight—
