Drosera.    June 17th    7O 45

3  2 Sticks with Blue-Paper Heads.    3 leaves with little square of Spinach Leaves on discs

18th    7O. 45' (n 10) leaf with hardly any inflection

(19'    ― ,O,) (20th, O) (21' 7O 30, O)

18th 8' (No 3) with all sub-marginal

(19' pretty closely inflected with some marginals)

(20'    7O 30'    I suspect beginning to reexpand

(21'    7O 30    completely open, the bit of leaf discoloured & bathed in slightly acid secretion)

18th 8'O (Blue Head;) with sub marginals & lam. on one side

19' 7O 30 lam. not inflected —& I think altogether not so close

20th 7O 30' beginning to expand (21' 7O 30' completely open)

Exactly The same results were observed when small squr bits of spinch leaves were tried.; the lam gland [illeg] frst secrtng a [illeg] medium amount of acid secretion & the leaves of the Drosera remaining inflected for 3 days.

June 20'    Drosera (I must say that fibrin not nearly do well dissolved as albumen meat, cartilage &c.)It is plain that fibrin excites D. very little

   7O 50' A.m.    Pure fibrin (B. Sanderson)

——

Stick (7)  2 2 bits — about 1/20' of inch think

(21' 7O 30', one bit dried up — the other had with few short surrounding tentacles closely inflected round it (22d 7O 30' these few gland have much liquefied the fibrin, but not dissolved it.)

      (I have put too small pieces, sufficiently to excite the plant)

23d 7O 45' I think I can see a trace yet (24' 8O 30 completely dissolved) 

 

Stick (2.) 2 bits (21' 7O 30'. dried up.) 22d 7O 30' the other bit all liquefied, yet I see atom undissolved — glands pale)

(23d 7O 45' I can still see atom I have moved it to another outer t. to right of fly.

(24' 8O 30' completely dissolved)

On other Plate 2 Black wool    Each with 1 Bit (21' 7' 30 1 has caused very little inflection & the other only the short immediately surrounding tentacles (22d 7O 30' both well clasped & short surrounding tentacles (23d 8O both completely dissolved; much secretion on disc acid in one case

20th 12O 50' 2 Bits on 2 leaves    sticks with rings on Hothouse plate (2O added a little saliva, as seem dry)

21' 7O 30' A.m.    Both leaves with lam. closely inflected, examined one carefully & all fibrin completely liquefied & transparent (22d 7O 30' I can see trace in other leaf which is now expanded) 23d 8O all dissolved in both leaves

June 22d    8O 27'    3 leaves (2 sticks with white wool)

Cats Ear    (Drosera)

bits of ear of cat B. Sanderson with cartilage of ear containing elastic fibres (abut 1/15' of inch square) (He has put do into digestive fluid) (Touched glands with saliva)

24th    8O 30' still closely inflected

25 8O    2 leaves almost reexpanded.— In one I can see only dried matter, quit thin & points drawn out into thread: in the other some little opake white matter left — 3d leaf still closely inflected)

The most transparent piece shows a network of elastic tissue fibres which do not disappear with acetic acid— They become more evident showing probably there was some undigested areolar tissue which the acid clears up—

(26th 8O third leaf still inflected

(27' 8    ― ―    beginning to open

28' 8O expanded—  all liquefied, but a good deal of opake matter left in fibre & little acetic. There are a great many elastic fibres and some other tissue which I cant make out. which dies not appear to be areolar, & some hairs
