Ap. 21' 1879    Radicles— Beans Caustic to surface Touch

10°. 30' a.m Rubbed for 2 or 3'" side of R. 4 mm from apex with Caustic (avoiding Sachs curvature)— suspended vertically over water, dark, Radicle dried with blotting paper — Caustic. dry. —Radicles long.

(1) 4°. 35' P.m Short R no effect

(2) ((also touched. apex in another direction)) 4° 35' curved to black (touch on apex no effect)

(3) 4° 35 curved at right ∠s to black

(4) 4° 35 curved at right angle to very slightly to black

(5) 4° 35 greatly curved

(6) shortish R. 4° 35 greatly curved.

4°. 35 P.m the spot was much too much rubbed & is now a large black spot— a single slow touch cd suffice but even this may check growth— yet it wd show contrary effect to touch on apex

22d 7° 50' every one, bent at least at right angles several Hooked; but black spot forms a pit much too much corroded— as if fire had been applied

April 22' 1879 Beans Radicles— Touched with   caustic

8° 20' a.m.       Beneath Apex

one single touch at 4 mm from tip of root cap. suspended over water in dark— rather young radicles.

(1) 23d 8° 15. gone quite straight

(2) 23' 8° 15   like (1)

(3) 23d 8° 15 still with Curvature where spot

(4) 23d 8° 15' still with curvature

(5) 23d 8° 15 still with grt curvature

(6) This one touched additionally on apex in opposition to Sach's curvature. 23d 8° 15 bent at right angles, but apex has also acted I think, for curvature at right angles to side where dot is beneath summit.

(4 35 too P.m much acted on several quite vanished); unfortunately I did not record state of all, but I believe all curved.
