Going to Pembroke Lodge Monday night. Send him the letter to grandmother (very glad he kept a copy, otherwise lost for ever in his aunt's clutches). Won't promise not to fall in love with Mariechen. Will go straight to Dresden after Burdetts. Reading James's Psychology, easy and pleasant; finding all the points he was maintaining against Logan. Send these books: all on shelf of his writing desk, except Nicholson, and Recent Economic Changes; Lotze's Metaphysik; Wundt, System; also "the few loose sheets of manuscript headed: Geometrical Axioms and those headed Absolute Position (one page) and Congruence (three pages) (all these were lying on my desk when I left Friday's Hill)." Also: Headlong Hall, Shelley; a few Henry James's and casual novels. Also Kant's Kritik. "The power of aristocracy is terrible socially, as I have reason to know."
