HS hopes in the future to show more fully "absolute emptiness" of James Martineau’s propositions; is glad CD approved of his article dealing with JM’s arguments. [J. Martineau, "The place of mind in nature", Contemp. Rev. 19 (1872): 606–23; H. Spencer, "Mr Martineau on evolution", Contemp. Rev. 20 (1872): 141–54.]

Thanks CD for Expression. Disagrees with his views on the genesis of melody; HS gives some reasons for believing it to originate in the natural cadences of emotional speech.
