Letter from Horace Lamb, 6 Wilbraham Road, Fellowfield, Manchester, to [Joseph] Larmor The passage which troubled him was to be meant as a demonstration of radiation pressure in the medium; he did not understand that there was any reference to reflection. His note was not meant to be printed, but if there is anything that Larmor might use, he may do so. He does not know what to do with the enclosed [not present] as he finds Royal Society regulations obscure.He has heard that A.R.F. [Andrew Russell Forsyth] has withdrawn as a candidate for the London professorship. 3 October 1912
