Letter from E T [Edmund Taylor] Whittaker, Mathematical Institute, 16 Chambers Street, Edinburgh, to Sir Joseph [Larmor] Whittaker promises to do anything he can 'in the matter of poor [John Hilton] Grace'. He will consult D'Arcy Thompson about his dealings with the Murdoch Trust and he will write to Scottish professors. Whittaker promises a personal subscription. He sends a paper intended to be read to R.S.E. [Royal Society of Edinburgh] reconciling classical and quantum theories of light. 2 February 1926
