[13 September 1880]
Trypsin — Leaves taken out Sp 13 — 11 to 11.30 a.m
Lime {2nd basal — plenty of starch, I think everywhere
(2nd apical none)
Lime — no starch in either basal or apical part. 1 specimen of each —addedK1+1 again to both, lots of starch in base
(Normal lime — starch everywhere nourished)
Ivy starch in both about equally — I think not equal to normal leaf.
Hazel — 1st apical specimen some starch, bad specimen
1st Basal — great deal of starch gone but not all I think of these 2, there is more starch in the apical-
2nd apical — lots of starch
2nd basal very little starch
3rd apical one piece, plenty, one none
Normal leaf plenty of starch, but not every stoma has starch & some patches of stomata have less than other places.
Normal leaf 2nd specimen — Again a good many with no starch
Cherry Apical (1st specn) no starch (readded 1 do)
Basal (1st) Patches of starch & patches of none ( readded 1 do)
Basal 2nd Hardly any (readded do)
Normal — everywhere starch
(Cherry 2nd Apical No starch certainly)
Effects of artificial fermented juice or starch infers
