My dear Sir

Your letter of the 8th received.¹ I enclose cheque for £25 and shall certainly be able to send you £110 and hope £150. But I shall not know the amount with certainty until I have written a statement for Mr. Caird, showing why I think favorably of your scheme, what you have done, &c. I am now pledged in honour to do this.² The letter to the Times can be kept in reserve till next year.³ Be so kind as to answer as soon as ever your work permits you all my queries; especially which year you commenced work and what you have expended. I will then write a statement, making it as brief as possible, and have copies sent to Messrs. Farrer,⁴ Caird &c.

My dear Sir | Yours sincerely | Ch. Darwin.
