From A. R. Wallace 23 July 1877
Summary
Thanks CD for Forms of flowers.
Further objections to "voluntary" sexual selection. Believes that he can explain all the phenomena of sexual ornaments and colours by laws of development aided by simple natural selection.
Excited by Thomas Belt’s "oceanic glacier river-damming" hypothesis. The last paper, "Glacial period in the Southern Hemisphere" in the Quarterly Journal of Science is particularly fine.
