May 21 — 74'. Phosphate of Ammonia 1 gr to 500 oz of Water (Water Hopkins & Williams) (1/2 drach) May 7O 45' to 50'
(5) 8O 26' about 30 inflected (10O 25 28 inflected) 9. all in nearly same state
(11O , 33 inflected)
(2O 30 all sub-marginals slightly inflected
(5O 30 a large number inflected, sub-marginals forming a fine ring on disc not hot day Temp 60° Plants brought from warm greenhouse
May 22 7O 40' in nearly same state, but sub-marginals forming fine ring.
(6) 8O 26 about 40 inflected (10O, 30, O)
2O 30' discals & sub-margins forming a ring, as in water specimens
5O 30' all but 25 to inflected — lamina immensely inflected
May 22d 2O. 40' enormously inflected; every t. except 1 inflected (Count)
(May 22'. 7O 40 added little water on account of evaporation)
(7) 8O. 26 about 42 inflected — (10O 30 about 53 inflected)
11O. (66 inflected or sub-inflected
20O 30 all but 24 inflected, or plainly sub-inflected,— none very very closely inflected. (5' 30' all but 17 inflected or subinflcted)
May 22d 7O 40 all the tent. except 4 inflected or subinflcted. (22d 11O 30' laminae inflected
(8) pale leaf 8O 30; about 21 inflected. (10O. 30' 24 inflected or sub-inflected)
11O (46 inflected)
2O 30' all but 17 slightly inflected, but none closely inflected; slight ring on disc
5O 30' in about the same state
May 22d .7O 40 every tent. slightly sub-inflected, & all but the 2 outer rows forming a fine ring on disc; & those outer ones all curved a little inwards: The whole lamina has moved towards footstalk largely & now 11O 30' strongly inflected.

22d 11O 30' conspicuous difference between the Phosphate & Water Spec. —
May 23d. 7O 40'
(5) not more inflected than the best most inflected water specimen
May 24th 7O 40 sub-marginal still much inflected, yet whole leaf. evid. reexpanded
(6) 23d. 7O 40' — lam. with blade turned over to pedicel. & almost all tent still closely inflected
24th ― blade still sub-inflected — most of marginal expanded
(7) ― lam still much inflected & tents. do.
24' 7O 40'
lam still slightly inflected, but all much expanded
(8) ― l am still inflected & almost all tents sub-inflected.
24th 7O 40 lam. still sub-inflected yet much expand— almost all the tentacles still slightly inflected.
May 24th 1O great difference between the 4 Phosphate though these are now beginning to reexpand & the 4 water specs.
May 25' 8O A.m. The one inflected spc. (8) in Phosphate still considerably inflected, whereas the 4 water spec fully reexpanded
