Writes to express his sympathy, and that of his wife, with NS on the death of HS, which was 'a great shock' to them. Refers to 'his great powers, his kind heart, and the universal esteem in which he was held', and assures her that his great qualities 'are not things that have perished'. Declares that he has 'left a name that will be remembered in English philosophy', and in ethics especially, 'as singularly impartial, clearsighted, and practical in a degree that few moralists are.' Refers also to his writings on political economy, which he regrets not having read. Recalls the time he and his wife spent with the Sidgwicks some years previously, and adds that his wife 'always speaks of Dr Sidgwick as one of the most charming persons she ever met.'
