Rubbed

(1) 17th 5° 15 P.m. rubbed like (2)— 18th 8° a.m. upper part slightly deflected from rubbed side

(18th 8°. 45 a.m. Temp 61°— sand-paper & shell-lac— 4° 45' P.m curved at rt angle from card—  Card

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

 

(2) 17. 5° 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 8° am no clear effect (—19th 7 a.m no effect)

Card & shell lac 

(4) 18th 8° 45' a.m Temp 61° sand-paper & shell lac 4° 45' no effect 19° 8° 15 no effect. but radicle has not grown well  Used 

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

(5) See under (1) for result 

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

(18th.. 8°. 30' bit of thick Bristle, gummed.   4° 45 no effect (19th 8° 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 5° 15' P.m rubbed laterally like no. 2. 18' 8 am curved to rubbed side

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

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

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

(18th. 8° 50' rubbed with needle 6 times on side of Black dot. Temp 61° .— 4° 40' P.m no curvature from dot (19th 8°. a.m. do) Rubbing

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

Bristle

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

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

Bristle

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

 

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

Bristle & Rubbing

(18th May 9° 15' a.m. Temp 61° 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 8° a.m. — A Horizontal with tip very slightly curved down

(Bean kept at etn 62°)

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 40° 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 8° am were on average 1 ½ inch long!
