To Michael Foster   26 June [1871]

June 26

My dear Sir

I shall have real pleasure in seeing you whenever you are inclined to walk over.1 We lunch at 112 on week days, & at 114 on Sundays— There is Coffee & Tea at 414 every day; so you will know when you can get some refreshment after your long walk—

If our Horses have not been out, I can send you part of the way back—

We return home on Friday or Saturday & shall be at Down I hope for a fortnight, possibly longer, & then I am going away for a month’s rest.—2

Can you tell me where I could buy a few grains of Curare poison or Ourari?3 I want some extremely for some experiments on plants, i.e. if, as I suppose, it is soluble in water or vegetable acids.—

Can you tell me anything about strength, i.e. relatively to acetate of strychnine: I mean if I find 1 gr of acetate of strychnine to 1. oz of water strong enough for my purpose, wd. 1 gr. of curare probably be strong enough.—4 I ask to save waste. Could I buy it in Paris, if I cannot in London.— Huxley5 could not aid me & suggested that you could.—

Forgive me thus troubling you. | Yours very sincerely | Ch. Darwin
