Thanks for letter of caution about Murray. He has offered to publish without seeing MS. CD thinks book will be popular to a certain extent. Lyell’s inducing Murray to publish Origin grates CD’s pride.

Comments on water rising in their wells.

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.

No summary available.

First part of Origin MS is with Murray;

CD hopes he has noticed ARW’s work fairly.

ARW is right in thinking that CD was led to believe that selection was the principle of change from studying domesticated productions and that after reading Malthus he "saw at once how to apply this principle". Geographical distribution and geological relations of extinct and recent inhabitants of S. America first led him to the subject, "Especially case of Galapagos Islds". Hooker and Lubbock are full converts and Huxley now believes in species mutation. "We shall live to see all the younger men converts."

Praises ARW’s work and spirit.

CD had actually written a letter to ARW stating he would not publish before him but was persuaded by Lyell and Hooker to allow them to act "as they thought fair & honourably".

Has read first sheets of JDH’s Flora Tasmaniae [introductory] essay [published separately as On the flora of Australia (1859)]. Criticises lack of evidence supporting views that best marked varieties occur at edges of range of species and that species remain under cultivation for many generations and suddenly begin to vary.

Thanks WBT for his help with poultry

and informs him about his forthcoming work [Origin].

Sympathises with family on death of WDF’s mother [Anne Fox née Darwin].

Sends details of fees at Moor Park hydropathic establishment.

Murray has read first three chapters of Origin and abides by his offer to publish.

CD agrees cultivated plants may begin to vary after some time and then may vary suddenly, but cautions JDH on lack of evidence. His explanation is that small variations are ignored until they accumulate.

Questions about stripes on mules.

CD suggests George Bentham or Joseph Prestwich for Royal Medal.

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.

Has FS observed the slaves of Formica sanguinea foraging outside the nest.
