Letter from A E H [Alfred Edwin Howard] Tutton, 41 Ladbroke Grove, London, to [Joseph] Larmor The papers sent are just what Tutton needed. He has also looked up the preface of 'Aether and Matter' but wanted Larmor's most recent views. He summarises his intentions for the chapter on light in his crystals book and notes that he is a believer in Larmor's view that 'the story of crystals may be one of the clues to molecular structure'. 18 December 1908
