Chemical Senses: Receptor Events and Transduction in Taste and Olfaction, Vol. 1 Book

I don't see that the eugenics movement moved much beyond this foundational document, either in politics or in scientific understanding, which is I suppose both a compliment to Galton and a judgment on his successors.

He should have said more about the nephews of Popes, which looked like the most promising piece of evidence in considering the basic nature/nurture issue.

I think implicitly it looks Galton wanted to turn humanity into a super-organism, like an ant-hill or bee hive. This might still be in the cards.

Also, I wanted to add that Galton displays what seems to me a sophisticated understanding of fitness landscapes and "evolution by jerks", even if only in a couple paragraphs near the end.
