Thanks for "people psychology", which in his opinion corrects some wrong ideas, especially in linguistics. Together with his friend [Diedrich] Westermann he made discoveries about the relationship of Sudanese languages. Makes remarks about sound pictures in the Bantu. Has begun work on a Bantu grammar. In contrast to Wundt, he does not necessarily see the cause for sound shifts in cultural progress and refers to his own essay on the subject.
