19th 8º. 15' a.m slightly curved from card 

 

(2) 17. 5º 15' P.m. rubbed on side of dot in back side 6 times on very apex enough to bend pin & shake bean with fine needle— 18th 8º am no clear effect (—19th 7 a.m no effect)

((a moderately thick Bristle from a Home-made brush flattened (0.33 in one diameter & 0.21 in another diameter.)))

(6) 17th 5º 15' P.m. rubbed laterally like no. 2. — 18th 8º a.m no effect   Rubbing

(18th.. 8º. 30' bit of thick Bristle, gummed.   4º 45 no effect (19th 8º 15' no effect ) then the Bristle was put on so as to aid Sachs curvature & is moved slightly in direction of Sachs curvature   Bristle

Rubbing

(7) 17th 5º 15' P.m rubbed laterally like no. 2. 18' 8 am curved to rubbed side

(18th. 8º. 30' a.m, bit of thick Bristle gummed on. Temp 61º— 4º 45' tip at right angle 19th 8º 20' has become perfectly straight.  Bristle

(8) 18' 8º. 30' a.m. Bit of thick Bristle gummed on. Temp 61º 4º 45' no effect 19' 8. 20' no effect, but this radicle has never grown, must be sickly need not count.

(10.) 17th 8º a.m thin bit of Bristle gummed longitudinally on apex 5º P.m slightly deflected laterally, apex had left bristle, pushed it on again —(18th 8º a.m deflected laterally (see back) for at angle of only 26º

(14) 17' 8º a.m. (like 13) put on back 5º P.m quite straight— 18th a.m possibly a slight effect for terminal portion a little   deflected from Sachs curvature  Gold-Beter skin

(15) 17' 8º am bit of thin Bristle gummed longitudinally to apex 5º P.m no effect —18th 8 a.m no effect

(18th 8º 50' a.m Rubbed 6 time with needle 6 time on side of Black dot. Temp 61º   4º 35' quit straight.) (19' 8º a.m do)  Rubbing

(17) 17th 8º. am bit of thin Bristle gummed long. to apex— radicle already curved to left, put bristle so as to counteract this curvature. 5º P.m I doubt whether any effect

 

18th 8º a.m. no effect (18th 8º 50' rubbed with needle as above.) 4º. 35 no curvature from dot

Bristle & Rubbing

(18th May 9º 15' a.m. Temp 61º 4 Beans A. B C. D placed with long radicle Horizontal & so arranged as geotropism & Sachs curvature wd bend downwards tips of radicles & bits of sand-paper & shell placed affixed so as to cause upwards curvature.

(over)

14v

19th 8º a.m. — A Horizontal with tip very slightly curved down

(Bean kept at etn 62º)

B quite horizontal

C appears first to have curved a little up in appropriate to geotropism & then apex a trifle down i card dropped off

D whole radicle from bean to end, so that chord about 40º beneath horizontal

Considering the geotropism act most powerfully on horizontal underside —it is as much as could be expected that the paper shd have reacted largely the combined influence of Sachs curvature & Geotropism —

There resides at the above 18th 8º am were on average 1 ½ inch long!
