Albury Aug 7 1871. Curare or Ourari, 4 gr to 1 oz (ie 1.4 of 1/28800 gr.) (Drosera) to glands ― put on 6 glands & left for about 20' & an atom of meat then caused splendid & very rapid movement.

Also a gigantic drop of same sol. on good leaf, left for 30', & then drop of saliva caused all hairs to curl in.

Hence ourari does not cause or stop movement – The contractile tissues (?) must be different, as might be expected, from the muscular tissues

Albury Aug 8 1871 with needle fix to stand drew out filament of viscid ball at nearly ∟' to filament, & so left it caused no movement.

Aug 9 ― After some preliminary & doubtful trials put a powdered pure chalk on glands & they all moved, & then put acetate of strychnine 1 1/2 gr to 1 oz Strychn on 4 glands — one moved spontaneously & slightly, & the other 3, after interval of 15' & 27', when chalk was put on also moved well!!!

Aug 11 ― 2 glands out of 5 moved spont. when a little of sol. of 1 1/2 gr. Strychn to 1 oz of Water put on 1 1/2 gr.

I have tried with sol. of 1/2 gr. to 1 oz. & does not make apparently the leaf in the least more sensitive.

Albury Aug 1871

Finally I can make out nothing about Acetate of Strychnine ― except that it occasionally causes movement of Hairs (& if strong blacken & kill glands)
