July 18' or 19th Hæmatoxylum Campechianum

Sleeps like Cassia, but terminus leaflets not turned back towards base of leaf. nor so much depressed — Belongs to same sub-groups, as Cassia — leaflets slightly silvery on both sides — In bud — leaflets turned upwards with lower surface outwards.— I syringed a leaf for 1' with water at 90° & shook another leaf for some 1' & no movement ensued.

Leaf shaken for 1' in water at 95° all silver removed & did not close. — all these observations must be repeated. —

20th 6˚ P.m. Leaves which I syringed are all spotted, & coated with a wonderful crust of blackish grey "Smut" — (seem to be a fungus.) It is highly remarkable that only older leaves, which are very imperfectly coated with bloom are thus affected, & the syringing with water at 95° wd have removed all that there was. We shall see that silver easily removed

This very important as showing now use of bloom.

Longish leaf including petiole & tip of terminal leaflets 2 1/4 inches

Logwood

Youngish leaf waved for 1' in water 84°-83° silver removed from margin of upper surface — same leaf for additional 1' silver quite removed; barely removed from lower surface. — another leaflet waved for 1' in water 90°-89° all silver removed & surface well wetted;— Silver almost removed from lower surface, which was fairly wetted.

The older leaves have very little & imperfectly silvered.

July 21st 11˚.— sponged 2 youngish leaflets (board marked blue) with water 90°-89° & they were then moderately well wetted. & put globules on 3 other leaflets (board marked red.)

(July 22d 8°. 30' sponged all leaflets with water at 95° of leaf marked with yellow wool to see if bleeds. No effect about used.)

July 31. 9˚ removed water from the 2 leaflets; one of which has a trace of yellowish specks, but cannot be said to have been injured— mid-ribs not browned, I managed to get drops to remain on of several other leaflets which were pinned down & none of these injured. The above 2 marked with white wool.

Leaf went to sleep at night (31')
