My dear Darwin

3 proofs reached me from the Contemporary Review of my “Theory of Heredity”¹ so I can spare one, and as I know you like to mark what you read, do not care to return it. I hope it will make my meaning more clear. The remarks printed as a note in p 5, but which I ought to have put in the text, will meet what you wrote about the Hymenoptera.²

I am most obliged for what you tell me about Brown-Séquard; I did not know of it, & will hunt up the passage to day (Thanks for the reference, received this morning)³

I should be truly grateful for criticisms which might enable me to modify or make clear before it is too late.

What a nuisance this modern plan is, of sending proofs in sheet, & not in slip. One can’t amend freely.
