Analogy between MH's love and action of light. All is ready for MH's arrival next week. Daughter Julia will spend month with J. M. Cameron. Miss Beaumont reports that JH's son John is recovering well from illness [at Clapham Grammar School?]. Cannot come to Collingwood Saturday; must work at 'Mammonium' [Mint]. Bring photography by JH for Mr. Hilhouse.
