Peacocks and sexual selection.
ARW’s sterility argument has driven CD’s sons half-mad.
There are so many doubtful points on the problems relating to sterility that they will never agree.

Warns ARW of dubious character of list of European alpine genera and species in volcanoes of Hawaii. Problems of geographical distribution in oceanic islands.
Admires ARW’s "Theory of birds’ nests" [J. Travel & Nat. Hist. 1 (1868): 73].
Discusses their respective views on birds’ nests, sexual selection, and protection.
Asks why, if brilliant colours of female butterflies are result of protective mimicry, do not males become equally brilliant? CD believes variation in females alone accounts for it, rather than protection.
More on CD’s objections to ARW’s views on protection and natural selection.
Sexual selection.
Criticism of ARW for too little esteem of the role of sexual selection as agent in giving colour.
Response to other topics.
The problem of dimorphic plants and their fertility.

Hopes ARW has not "murdered too completely your own and my child" [natural selection] in his Quarterly Review article ["Sir Charles Lyell on geological climates and the Origin", 126 (1869): 359–94] on Lyell’s Principles [10th ed.].
CD is attributing more significance to useless variability in new [5th] edition of Origin.
