Appleton’s cannot alter their plates so as to reproduce revised work [Origin, 4th ed.]. Has made it clear that CD could not do otherwise than object strenuously to course they intend to pursue, and has asked them to return the sheets. Wishes CD’s publisher would supply U. S. market with large numbers of copies, as the English edition could well compete with any American one. Encloses [statement of sales of U. S. edition of Origin to 1 February 1866].

Proposes to delay issue [of 4th ed. of Origin] until November to obtain better market conditions. Now printing 1250 copies.

Explains practice of not cutting pages is due to propensity of English public to read books without buying them.
