Ph. of Lime
May 5 8° A. m. All specs same state
May 6' 8° A. m. all 3 Blue-Heads — most closely inflected — the secretion from some outlying tent. (now acid) which have not touched the Ph. — but the secretion on the lime not acid & in one leaf there is still a drop.
― 7th. 8° do do. — secretion on disc not acid— leaves look flabby — an extra leaf on which the some secretion had run now inflected & also flabby.
8° all closely inflected, & dry — one dead.
9th all 4 almost dead. — some never recover
(z) examined dead leaf much phosphate left — very little is dissolved glands all dead & blacken round the little packets of Ph.

Phosphate of Lime pure white powder precipitated sent by Dr Frankland (30 days in April)
Apr 30th 8° 55'
Two red sticks — The phosphate with a little water
Jun May 1 8° 10 one with lamina — sub-inflected — The second with only trace of inflection of sub-marginals —(May 2d do)
May 4th 8° A. m. same state
― 6 ― ― 1 unaffected as before— the other still well inflected
7th do do do, but looks dry
8th ― do
10th the other leaf with some few tentacles recovering
Two plain sticks with pins — Phosphate moistened with saliva
Jun May 1. 8° 10; — one with lamina sub-inflected — The other with many tentacles inflected — May 2d Both with same somewhat inflected.
May 4' same state
― 6th — one leaf inflected & seems killed — the other beginning to expand
7th 1 quite dead & inflected — the other half expanded, but seems drying (z) (Back) (8th do) (9th dead almost)
The Phosphate was at 2 ends of disc. & it was pretty how tentacles directed to these 2 points
May 3d 8° 15' — 2 sticks Blue Heads— 3 leaves with a good deal of the Phosphate moistened with water — (Merely to see how long remain clasped). (May 4' 8°. All 3 leaves closely inflected. (over) All 3 leaves with larger drop of not very viscid & not acid secretion hanging to edge of [illeg] leaf— I never saw such a case before!!! (May 5 not acid
