Sept 3d    8O 43'    Citric A. 1 to 437 of w.    4 leaves in 2 dr. of above

(11O. 15', no effect)

(2O 30' perhaps a trace of inflection

(2O 45', no inflection

Sept 4th 8O 18' do.— washed & put in Phosphate of Ammonia 1 gr to 20 oz.

   8O O 33' — some inflection

   9. 9'    decided inflection, but not extremely great

   10 28'    3 leaves decidedly inflected, the 4th a little

   1O    3 leaves strongly inflected; the 4th considerably

Sept 5'    8O 30    the 3 leaves still inflected & the 4th leaf partially so.

do    8O 50'    Oxalic A. as above. Leaves as above. (11O. great much inflection glands pale & water strongly coloured pink)

   (4O 50'— tremendously inflected— put in pure water)

Sept 4th    8O 20'    do— very state — tentacles very dark red, like the spec. in Acetic

Sept 5th    8O 30    utterly dead glands colourless

(6A

Tartaric Acid [illeg] —3 drachs— of 1 gr to 1 oz on 3 leaves    Sept 9thnil    8O 34' —(These 3 leaves have had by accident twice too much of each acid)

   9. 4' some no inflection in .(9. 45' ,O) (12O, O)

   (2O 35 ,O) (Sept 9th 8O 30' no inflection except a few tent over pedicel, as often observed & apparently due to absorption by cut end — added Ph of Ammonia (1 gr to 10 oz)

   Sept 11th    8O A.m    no inflection, so that Ph of Amm. has no action after Tartaric A.    any more than after water

Chromic A.    do strength.    8O 39' 24—40

9. 4' some inflection in all 3 leaves (9. 12' [+] 21 [=] 33 unmistakable)

   9. 45' considerably inflected aft 1h.

   10O 40'    closely inflected (12O glands discoloured / after 2h

   (2O 40' p washed & put into pure water

Sept 9 10'    8O 30' quite discoloured & evidently dead.)

Arsenious A.    do strength & quantity 8O 43' 17

   9. 5' 17 Considerable inflection. — 9. 12'17 plain inflection

   9. 45' greatly inflected    (12O glands not discoloured

   (2O 40'. put into pure water

Sept 10'    8O 30    one leaf seem expanding — leaves look fine & not much discoloured changed water

Sept 7th 10th 8O    paler not expanded

   13th not expanded evidently dead — no plain segregation

(6B

Formic Acid. Sept. 17th 10O 10'    4 leaves (2 pales & 2 red in 2 dr. of F. A. 1 gr to 1 oz

(10O 35' a trace of inflection) (11O, decided slight inflection)

(2O 15', 3 of leaves    sub-inflected

(4O 45'    very moderate inflection indeed, the third leaf only a few tentacles)

Sept 18th    8O    scarcely any inflection not more than water often cause    washed & added Phosph. of Am 1 gr to 20 oz

Sept 19th    9.    2 leaves considerably inflected with segregation, I do not doubt that the Phosphate has acted a little

Gallic A    10O 15' 3 leaves to 1 1/2 dr. of same strength    (2 pale & 1 red leaf)

(11O 5' perhaps slight inflect) (2O 15'    red colour effect) (4O. 45', O)

   Sept 18'    8O    no inflection no effect

Benzoic A.    10O 17'.    2 pale & 1 red leaf to do same strength

(11O 5' glands all pale, tents on & round disc inflected — water coloured pink

(2O 15 all tent of all 3 leaves sub-inflected very regularly but not closely.— all glands colourless.) (4O 45' same state, washed & put into pure water) : tremendous lot of mucous secreted, all the outer tents project at right angles.) (Sept 18th  do — water yellow ! suddenly killed.

Sept 19th    9. — water again coloured yellow— leaves very pale brown in the same state of semi-inflection— evidently dead—

   (Yet the sol. of Benzoic, only just perceptibly differed in taste from pure water) a wonderful poison !

NB I have tasted again with a little again towards back of mouth, but very little— more taste on tip of tongue Even just dipping a leaf in the do Benzoic Acid, which clung to leaves for short time paled all the disc on it

Sept 17'    10O 25'    Tannic A    1 part to 1 1/2 gr of A.    1 gr to 1 oz or 437. (2 red leaves & 1 paler )

(11O 8' 2 leaves no certain consid inflected, though slightly

   2O 15'    do—    glands not darkened.)

(4O 30' the 2 red leaves have here & there a tent inflected.

Sept 18'    8O    no effect — washed & gave Ph of Amm

   19    9'    no effect

 

Succinic A    10O       same strength

   (1 red & 2 pale) (11O 10' 1 red leaf perhaps inflected

(2O 15' red leaf consid inflected ,2 pale leafs very slight

(4O 50'    the red leaf have all those on disc & above round it closely inflected, the outer ones curved; the 2 green leaves with discals & adjoining ones inflected

Sept 18'9th— red leaf closely inflected, very many of glands on all leaves quite pale —    fluid coloured very pale pink — washed & gave pure water

Sept 19' 20' 8O — the red leaf somewhat expanded, but not the gland of marginal    tentacles white— the 2 green pale leaves fully expanded, but with many of the glands on the marginal tentacles white. Thus this acid does not kill the leaves but injures many of the glands
