Abinger Hall | Wotton Surrey (Post Town) | (Gomshall Station) S.E.R.

〈J〉uly 28th

Dear Sir

I write one line to acknowledge & thank you for the letters.—2

I have so poor a metaphysical head that Mr Spencer’s terms of equilibration &c always bother me & make everything less clear3

yours very faithfully | Ch. Darwin


The year is established by the relationship between this letter and the letter from G. J. Romanes, 24 July 1874.
See letter from G. J. Romanes, 10 July 1874 and n. 5. Spencer had substituted the terms direct and indirect equilibration for adaptation and natural selection.
