Dear Eyton

Your note has been forwarded here, where we are established for a short time for health sake.—² I thank you very truly for taking the trouble of sending me the reference; I think I am acquainted with them but will take your note home & then see. I am heartily glad to hear of your two intended publications.³ That on skeletons of Birds will, I presume, be a laborious undertaking. Just before I left home I broke ground on the skeletons of Pigeons; ie I arranged them preparatory to comparison;⁴ I daresay I may have to consult you on this subject; & if so I trust to your kindness to assist me.—

I am, also, employed in drawing up a long abstract on my notions about Species & Varieties, to be read in parts before Linnean Soc^y. Whenever it is published late in the autumn, I will send you a copy. My bigger Book will not be out for some two or three years.—

With many thanks.— Believe me | Yours very sincerely | C. Darwin
