P. Lusitania

July 8' 2° 30 2 bits of albumen on flower peduncle— above rectangular bend (red stick, one near observer) & one bit on calyx of flower to right— N.B glands on petals, as well as calyx.

9th 8° 15' no effect pushed albumen to margin

(9th I cannot see that glands on flower stalk have any powers in dissolving the albumen)

(10th 8° 30 albumen hard & no increased secretion)

[82]

(3) 8h

8° 2° 40 — Pieces of albumen along midrib (3) for 3/4 of length of leaf by no 7. & on other leaf to right— NB Bristle prevent le albumen coming int very close contact —

9th 8° 15' no effect on either & pushed them both close to margin which is very little involuted (11°, 45' whole margin of both leaves quite folded over, so that edge touches lamina of both leaves by Pins)

(10th 8° still inflected as much as ever— opposite margin not affected)
