April 5. Bean fixed with long pins vertically on Hilum in damp air in almost darkness. Dark Hand[illeg]

I perpendicular down with glass oblique to Sachs curvature put on about 2°. 30— Ap. 6th 8° a.m curved a little from glass, but glass does not extend to apex. 4° 30' Pm removed glass, for not bent & put on curved card (Ap. 7' 8° a no effect, quite straight— put on fresh & narrower card

4°. 30' not at all bent — put on fresh card more transverse. I see tip brown perhaps injured no effect though thrice tried

II. Ap 5' a little naturally inclined in line of ↑ put on glass so as counteract this curvature— radicle though inclined is straight beyond point of seed-coats— glass plate  affixed about 2°. 30

Ap. 6' 8° a.m curved directly away from former direction & at rt angles to Sachs curvature. Ap. 7' quite straight fixed new bit of card, narrow 4° 30' not bent (a)

III — almost vertically down— plat put on so as to increase the slight deflection from perpn perpendicular.— but radicle is straight Plate affixed about 2° 30— Ap. 6th 8° a little curved in direction of Sachs' so tells nothing— 4°. 30' P.m removed glass & put on curved card. (Ap. 7' 8° a.m a little curved from glass plate

IV injured radicle with pin

V. vertically down & short — plate affixed (4° 45) so as to oppose favour Sachs' curvature Ap 6' 8° am curved in Direction of Sachs; removed glass— Ap 7' 8° a.m. tip curved in direction opposite to Sachs curvature

Ap. 6' 8° a.m put on larger splinter so as to go beyond apex & a little way up side.

April 8th 8° a.m no effect on any of those on back of Page

(Two beans with old & long radicles which I previously tried with bits of card were well acted on, one had its tip rolled like a French Horn— the other much bowed.)
