Summary

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.

Summary

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

Summary

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.

Summary

Lyell has been strongly urging John Murray to publish CD’s book [Origin]. JDH feels Lyell overestimates the public interest in such works.

Gives examples of plants showing most marked varieties on the edge of their range.

Summary

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.
