Comments on Wallace’s Malay Archipelago.
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.
ARW’s review of 10th ed. of Lyell’s Principles [see 6684] is admirable.
But he differs "grievously" with ARW on man. CD sees no necessity for an additional and proximate cause.
On butterfly scales: there are many secondary characters which baffle conjecture.
Was forced to make additions to Origin as short as possible.
