My dear Hooker2

Yours to hand thanks for the information received I have sent you the notes on Volcanic Islands for your inspection when you have read them kindly return them to me as I must rewrite and correct them I have been very busy since I came here it seems to suit me here and I am now determined to show the people the gift of mankind in regards penmanship of a unusual kind which they seldom see

Believe me | Yours Faithfully | C Darwin


An address CD never used. This letter is either a copy made by an inaccurate copyist who interpolated details or a forged CD letter.
If this is a copy of a genuine CD letter then ‘Hooker’ must be a mistranscription. CD would not have addressed William Jackson Hooker so familiarly, and his son, Joseph Dalton Hooker, had not yet returned from the Erebus voyage. The addressee was possibly Leonard Horner, who would have been interested in the notes on volcanic islands. CD worked on Volcanic islands during 1843 (see ‘Journal’; Correspondence vol. 2, Appendix II).
