Veg. marrow Jar C

23d. 4º 50' P.m placed germinating radicles half immersed in water on study Table, but now (24th 8º 50') had hardly grown, so poured away some water & left in damp air on Study Table.

4º 45' grown very little fixed sq. on 3 R.s 25' 8º 30' no effect

25' 8º 30' fixed sqr with asphalt or shell-lac. on all under hour grown better— 5º P.m these look much better than other lots— several are inclined from sqr, but tips not abruptly curved from them— These grow mostly in direction opposed to Sachs curvature & therefore great contrast to former lot— see under what condition raised— Might be curious to investigate whether temperature or immersion at first in water does not modify Sachs curvature

26th 8º 30' several are curiously inclined from card— I do not know what to think. — (26' 4º 45 put on card in opposition to existing curvature & marked with pin 2 radicles— 27th 10º 45' one perhaps has acted, the other not at all— The evidence from this jar altogether doubtful

23d 4º 50' P.m fixed with shell-lac. sqr. on 6 Radicles in air on sand-bath. (24th 8º. 30' had grown greatly; no effect. sq. dropped off 4 of them— fixed on the 4 oth dropped ones. sq. with asphalt.— The Radicle grow strongly to Sachs.

4º 30' P.m. no effect.

25' 8º a.m no effect— now immersed Radicle in water

— 4º 45. cards all washed off. — not possible to fix them with asphalt or shell-lac.— 4º 50 fixed with shell-lac. sqr on sqr 6 secondary roots & exposed to damp air on sand-Bath

26' 8º 20' out of the 6, 2 have decided bend some way down, in direction from sq.— & tip does not touch sq. in another case & in another case sq. too Heavy to lift— 8º 50' fixed on some more small sq. but they are so flexible they bend with weight— 26' 4º 40' P.m no effect

27' 10º 40' a.m.— One is slightly kinked, as ought to occur from square

Veg. marrow. Jar B A

23d 4º 50' put several germinating seeds half immersed in water on sand Bath, but radicles (24th 8º 30') had hardly grown & what little had grown had curved abruptly to Sachs; so now left in damp air on sand Bath, but I fixed sq. with asphalt on 2 of the best. (4º 40' forgot & shook jar one washed off)

25' 8º a.m. no effect— Rad have hardly grown at all Immersed Rad in water on sand-Bath here (5º P.m. look wretched will not grow)

28' 8º 30' a.m. do. do.)

After they have grown a good deal: then try immersion in water.

July 24th 9º a.m pinned several seed on cover & left in damp air on sand-bath. 4º 40' fixed with asphalt sq. on 3 R

25 8º 30 have grown very badly, hardly at all — Left on Study Table sq. dropped off 2— 1 perhaps affected by sqr

25. 5º P.m. The main radicles have never developed— I suppose too hot but the secondary ones are now developing.

26' 8º 40' a.m fixed small sq with shell-lac on 8 secondary radicles— main (& on 1 other main radicle— others grow miserably: 4º. 50' no effect

27th 10º 45' no evidence of action on secondary roots

25' 5º Pinned 2 Sultan Gourds on cover. Sickly
