Down, | Beckenham, Kent.
Dear Sir
I am extremely obliged to you for your great kindness in writing to me at such length.2 I wish I had known of the Atropia; & perhaps I shall have time. to try it next summer. But as I have tried several extracts & as they are prepared apparently in the same way, without the use of any animal matter, the trial, as far as it goes, is fair.3
With my thanks | Yours very faithfully | Ch. Darwin
