Again thanks CD for trouble in arranging for translation of Für Darwin.

Sends addition answering critics of his idea of insect metamorphosis [see Möller ed. 1915–21, 1: 259].

Agrees with Charles Lyell’s suggested English title "Facts and arguments in favor of Darwin", although perhaps more accurate to call it "Darwinism tested by Carcinology" or "Carcinology as bearing on the origin of species".

Says any profit should go to CD for his trouble and expense with the translation.

Thanks for seeds of Eschscholtzia.

Gives observations on number of climbing plants, including Dilleniacea, Marantacea, Catasetum.
