My dear Henrietta,

I do not know whether you have been told that Murray reprinted 2000, making the edition 4500, & I shall receive 1470£ for it.¹ That is a fine big [sum]. The corrections were 128£!! Altogether the book, I think, as yet has been very successful, & I have been hardly at all abused. Several reviewers speak of the lucid vigorous style etc.— Now I know how much I owe to you in this respect, which includes arrangement, not to mention still more important aids in the reasoning.² Therefore I wish to give you some little memorial costing about 25 or 50£, to keep in memory of the book, over which you took such immense trouble. I have consulted Mamma, but we cannot think what you would like, & she with her accustomed wisdom advised me to lay the case before you & let you decide how you like—

I have been greatly interested by the second article in the Spectator & by Wallace’s long article in the Academy— I see I have had no influence on him, & his Review has had hardly any on me—³

We go to London on April 1^st. for a few days, in order that I may visit & consult Rejlander about Photographs on Expression—⁴ I think I shall make an interesting little vol. on the subject.— By the way, I have had hardly any letters about ‘the Descent’ worth keeping for you, except one from a Welshman abusing me as an old ape with a hairy face & thick skull.⁵ We shall be heartily glad to see you home again.⁶

Goodbye my very dear coadjutor & fellow-labourer | Your affec^ate. father. Ch. Darwin.

Love to Langtons⁷
