Summary

Charles Lyell has asked WE to pass his opinions on the MS of Origin to CD via Murray. WE is convinced of the value of CD’s researches but "to put forth the theory without the evidence", as in the MS, "would do grievous injustice to his views". The omission of these facts reduces both the philosophical and popular value of the work, by virtue of its dryness.

Supports Charles Lyell’s suggestion that CD should first publish his observations on pigeons with a theoretical outline, for "[e]very body is interested in pigeons". Such a work would generate wider interest and be better understood. A subsequent, larger book would then be approached with impartiality "not to say favour" by a wider public.

Summary

Comments on the Origin. Outlines difficulties he finds in CD’s theory. Believes CD must define natural selection more accurately and mentions instances in which that principle is an insufficient cause to account for the form of certain structures.

Summary

Suggests HF investigate hippopotamus tooth.

Has heard HF is very antagonistic to his views on species. Cannot believe a false theory would explain so many classes of facts.

Summary

Has heard that CL has spoken to John Murray about publication [of Origin]. Encloses prospective title-page. Asks whether he ought to tell John Murray about unorthodoxy of the book.

Summary
