My dear Sir
Will you look at the enclosed Title page & make any additions or corrections to it & return it for press.1
I have no doubt when the Index is made & set up, you will be very anxious for copies of the work & it would be just as well for us to have Vol 1 put in the Binder’s hands at once; as this will expedite matters.2
Yours faithfully | Robt. Cooke
C. Darwin Esq
I find the Index to your work on Animals & Plants occupies 54 pages
& the one in Origin of Species but 15 pages.3
Have you any idea as to what the Index to the new work will occupy?
Sends title-page of Descent for approval. Asks whether CD has any idea of size of index.
