July 3d 9º flowing matter just perceptible greenish matter & tinge of purple chiefly greenish [sketch] (9th. 3º C of Am added 1 gr to 1 oz) (Almost white leaf) (Used)
9º 13 greenish atoms formed currents increased
9 14' clear aggregating [sketch] — I think near surface
9º 16' grp at (1) 9 17 grp (1) now 1/2 way down cell
In some other cells such groups much increased in size — all greenish
9º 20' (2) almost filled up with aggregating green matter Current not more plain or quick
9º 27 perfect sphere in some of cells but not in mine —(aggregation of sphere, green)
10º 30' some tendency to all gr matter collecting at lower end of (a). not in (b) some beautiful greenish spheres in some other cells
10 40' same state
11º 45' The green matter near gland never formed spheres; but lower down fresh spheres & in glands Ø
[93v]
Circulation in lower cell— when 1 or 2 dark purple spheres formed— the whole content of cell have formed only 1 or 2 balls—
Accordng to tint of purple — so more or less aggregated matter —
There are no other spheres coloured or colourless (Used)
5º green matter in same state & all spheres now similarly broken up
(2
10º. 10' 1 gr to 1 oz
[sketch] gland
10º 23' now bit of purple matter circulating, apparntly derived from end of (a) — I do not think content of cell fluid, but pulpy
10º 25— whole cell now full of purple matter no space at end of (a) — whole purple mass is flowing
The separate spheres now much quicker
12º now quite full of dark purple matter flowing protoplasm thinner— spheres forming in several cells
12º 15 5 — 7 small spheres — some travelling rapidly — cell still full of dingy purple matter spheres at different levels travel along walls
12º 30' — 1 good-sized sphere & 3 smaller one — The spheres evidently become very dark as whole cell now becoming paler; especially a cell near gland 12º 35' smaller cells spheres still circulating
12 45' good large sphere with 1 or 2 smaller, cell paler sphere 2/3 diameter of cell small spheres circulating 1º the big sphere has travelled up to near upper end of cell —
1º 15' larger sphere has now travelled to lower end of cell 3/4 of diameter — 2 other growing spheres — Spheres have appeared in adjoining cells the large sphere travel far slower than small one — The biggest one stationary, all diameter of cell Ø
[94v]
1º 45 the 2d sphere has now grow bet 1/3 & 1/4 of diameter of cell — there are 2 other minute spheres — cell considerably paler, of the 2 little spheres one red, one colourless— I see even bigger spheres do change slightly their places
(2º 35' large spheres = diameter of cell — 2d alm 1/7 of size both very dark red & 2 small ones — cell very pale, content seem to come close up to wall — invaded by pale purple)
3º This in appearance as if the pale purple was breaking up
3º 35 I certainly think pale purple is braking up.
4º 20' cell almost colouless pale purple colour within a little separated from wall — no trace trace of any current
5º same state — one of smaller spheres is travelling — & I can see slow & slight travelling of pale purple diffused matter.
6º 45 the cells almost without a trace of purple, but at upper end a cloud & here 4 minute new spheres are forming & at lower end there is also a perfect cloud; but as yet no sphere— (Since midday C. of Am 3 gr to 1 oz has been added
July 3d 8º A.m — 6 small spheres at upper end— the 2 old large ones & one small one at lower end — Every trace of purple gone — some greenish matter only partly aggregated — Sphere solid by pressure crushed — Still oscillating movement
