Pot I

Formic a. to 1 dr or even slightly with 8 dr. of water & with S. of Quinine act

Pot II. Curare Curare powerful, but seems deadly when Formic a. added so try very weak sol of latter.—

Pot. II Acetate of Strychnine + Formic a. seems most powerful yet mixture [illeg].

— Valerianate of Atropine + Formic. a. seems especially powerful.—

Possibly Oleic a. acts & miastic; for I can see no swelling from Propionic a. Caproic or Butyric—

Pot III. Propionic a. worth trying 1 drop to 4 dram of water — perhaps try + acetate of strychnine or Val of Atropine.—

Try Boracic Acid.

Oak very important — S. of Quinine has caused swelling on stem of Oak & possibly on midrib of leaf— Try Acetate of strychnine & Val. of Atropine with or without Formic acid weak.— If any Formic a. must be very weak, for has killed leaves.
