Thanks WED for checking through the proofs of a new [6th] edition of Origin.
My dear William
I received this morning the last proof, & I must thank you cordiallyfor all the labour & anxiety, which you have saved & for all grindingwork which you have yourself undergone.—f1In one page a whole line had got misplaced, which I see hadpuzzled you & at first confounded me.—
I shall not want the Preface, Index &c looked over by you, sothat your work is finally done.—
I am so glad we shall see you on Sunday.
Yours affectionately | C. Darwin
