Thanks for HS’s Essays: [scientific, political, and speculative, vol. 1 (1858)]. Admires his general argument for the development theory.
CD is preparing an abstract on change of species. He treats subject as a naturalist, not from a general point of view. Otherwise he might have quoted HS’s argument to great advantage.
CD particularly liked articles on music and style. Expression is a favourite topic with CD. Agrees all expression is biological.
