Summary:
Apologises for saying more than was necessary in his previous letter. Although he feels gratitude and esteem for CD, he execrates those who use natural selection to oppose man’s higher interests and impede his advance. Has seen Huxley’s Man’s place in nature for sale among a crowd of obscenities at most Italian railway stations.
