To Benjamin Silliman Jr   4 December [1860]1

Down Bromley Kent

Decr. 4th

My dear Sir

I must trouble you with a few lines to thank you very sincerely for your note with some additional information on the Cave-Rat2 & for your printed letter, which I well remember reading some years ago in your Journal.3 Several of your statements in your letter have interested me much, & the whole subject of these cave blind animals seems to me eminently curious.—

I am much obliged to you for telling me about Prof. Dana;4 pray give him my very kind remembrances; I believe no one, except his personal friends, will more rejoice at his perfect recovery than I shall.—

I am preparing a new corrected Edition of my “Origin” & shall take the liberty to quote a few words from your letter on the Cave-Rat.—5

With sincere thanks & respect, pray believe me | My dear Sir | Yours sincerely | C. Darwin
