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

10º. 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) 4º. 35' P.m Short R no effect

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

(3) 4º 35 curved at right ∠s to black

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

(5) 4º 35 greatly curved

(6) shortish R. 4º 35 greatly curved.

4º. 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 7º 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

8º 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 8º 15. gone quite straight

(2) 23' 8º 15   like (1)

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

(4) 23d 8º 15' still with curvature

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

(6) This one touched additionally on apex in opposition to Sach's curvature. 23d 8º 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.
