12th

My dear Sir

One line to amend my request, if you try the C. of Ammonia experiment.— please drop the third drop on midrib of leaf on inside or upper side of leaf.—

Yours | C. Darwin

I am sorry that you have my Origin;2 I hope you won’t think me bothersome, but would you like to have my Journal of Researches or Travels?3 I shd. like to send them to you.—

If Dionæa is allied in its moving apparatus & whole structure to Drosera, as I suspect from what little I have yet seen; then the absorbing surface, wherever that may lie, would be shown by C. of Ammonia causing contraction; & that is why I want you to try, middle parts of lateral disc & midrib & sensitive Hairs (& marginal Hairs?)
