July 8th

2º 40 [-] 25 [=] 15

Black stick

(1) 8º 25' bit of albumen on glands well secreting viscid matter — sides symmetrical — albumen placed about 1.2 way between midrib & curled in margin (10º 40 has excited grt secretion & margin of leaf rather more folded over on that side.) (12º greatly inflected), inflection extending up almost to apex of leaf.)

(9th 8º edge rolled over so as to touch blade, & extends to [illeg] about the within 1/20th of inch of mid-rib — I have never seen such involution in P. vulgaris

(10' 8º has begun to open again)

11th 8º 15 quite open some with albumen, 1/2 liquefied left

(2) 8º 30' stick with [illeg] bit of albumen under involuted edge near apex — gland secreting (10º 45' much secretion) —

(9th 8º decidedly more involuted, than opposite margin, but not greatly so)

(10th, 8º somewhat opened)

(11th 8º 15 quite open — some albumen left.)

8º 35 Stick 7 chain of Blue-Glass

(10º 45' no clear effect) (12º I think inflected)

(2º 30' certainly some inflection & decided secretion)

(9th 8º no increase of inflection & secretion has ceased & almost dry)
