4th edition of Origin will soon be bound. Suggests sending copies to scientific periodicals that might notice it. Hopes JM will specify in advertisements that the work is corrected and enlarged. Hopes pages will be cut. Only insanity accounts for this not being done in England.

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].
