Accepts CD’s proposal for new revised edition of Origin; will pay $50 [dollars or pounds!?] for casts of the plates and pay CD on sales.

Appleton edition of CD’s Journal of researches [1871] still selling well.

Also wants plates sent with CD’s new work on Expression. CD should arrange this with Murray’s.

Enclosed account has had charged against it difference in costs between type composition in the U. S. and securing stereotype plates from Murray. CD should insist on securing plates from the London publisher of all future books, otherwise Appleton unable to pay 10% of gross price.
