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
