On the strength of CD’s details about his work on species and his knowledge of CD’s former publications, JM offers to publish [Origin] without seeing the MS.

Accepts JM’s terms for publication of Origin. If, on reading the MS, JM thinks it will not sell, CD frees him from the offer. Will send chapters soon so he can judge. Though some parts are dry and abstruse, CD thinks it will be interesting to "those who care for the curious problem of the origin of all animate forms".

Sends title and first three chapters [of Origin]. Thinks first chapter will interest the public and is sure views are original. If JM thinks otherwise, he should freely reject the work. Chapter 2 is dull and abstruse, chapter 3 is plain and interesting.

Will send first six chapters [of Origin] for the press. Sends data on size of MS and book. His "beau ideal" for type and size is Lyell’s Manual [of geology] 1st ed.

Important to his health to get the work printed quickly. Must leave home soon to stay for months at a water-cure establishment.

Asks printer to send a proof-sheet a day until he gets well ahead.
