My dear Sir

I am much obliged for your extremely kind note.² I cannot speak positively about the Sequoia, but my impression is that Heer found it in the lignite beds of Devonshire.³

Since you were here my wife has read aloud to me more than half of your work and it has interested us both in the highest degree & we shall read every word of the remainder.⁴ The facts seem to me very well told and the inferences very striking   But after all this is but a weak part of the impression left on our minds by what we have read; for we are both filled with earnest admiration at the heroic labours of yourself & others,

with hearty respects and our very kind remembrances to M^rs. Brace.⁵ | Believe me. | My dear M^r Brace. | Yours very sincerely | Ch. Darwin.
