Aug 13 9˚ 30' Cotyledon (Echeveria) pulverulenta old Plant 1877

2 leaves (one of which had before 1/2 open surface) & the other had water on it now had whole of both upper & lower surface cleaned.

(The bloom forms a cake which can be cracked of like whitewash— can be knocked off by drop of water.) Leonard marked with Re Blue dot.

Sept. 22d. I cannot see that any bloom removed, or any injury to leaves wherever it was removed.

Nov. 22 I can see no injury to the cleaned leaves. Feb 1st. do. do

It is clear that good or evil affects whole plant & not individual leaves except as protection from sun

This is the result of my general experiments

Cotyledon. pulverulenta of Aug 10th This must be false name (I think orbiculata) (rounded leaves & opposites not turning red like kind with pointed leaves. —)

Aug 13th. 9˚ 30' — cleaned both surfaces of 3 leaves. — Blue dots on edge.

Aug. 30th Bloom on Both surfaces perfectly removed so that younger cleaned leaf cd. not be distinguished from opposite one which had not been cleaned; the bloom on an older leaf partially removed.

Aug. 30th 10˚. 45' cleaned right half, upper & lower surface of same leaf again to see how soon renewed; now it is of bright pure green.

Sept 3d 9˚ A.m. longitudinal irregular stripes of bloom have reappeared on both surfaces: this is clear for by a bit of sponge I wiped of transversely in middle of leaf in narrow space.

Sept 6th whole surface, except the transverse fresh streak well covered with bloom — upper better than lower surface — not so thick as fresh leaf

Sept 9th The transverse streak made on Sept 3d now almost obliterated so that on the streak bloom renewed for 3d time.

Sept 12th 8˚ A.m. The 1/2 leaf now well covered with bloom, but not so thick as opposite side: the transverse stripe almost wholly recovered with bloom, so I again made a transverse stripe with bit of sponge.

[157v]

Sept 18. The transverse stripe which was made on 12th, almost perfectly recovered with bloom. The whole half-leaf not so thickly as opposite side which has was never been removed.

Sept. 19th 4° 15' cleaned the transverse stripe again.

― 30' I see a little bloom on stripe.

Oct 10' a little bloom, wiped it again

Feb 1. 1878 I can see no injury to cleaned leaves.
