Letter from William Crookes, 7 Kensington Park Gardens, London, to [Joseph] Larmor Crookes is pleased to hear that Larmor will put his name down to give a Royal Institution lecture, and gives a provisional date for this. Crookes also suggests that some typical experiments are shown during the lecture, and states that if Larmor would like to include these then Sir James Dewar has offered to prepare these on his behalf. 8 February 1908
