Copy letter from James Hopwood Jeans, Secretary of the Royal Society; to Professor [Henry Edward] Armstrong, FRS. Informs that the Council are glad Henry Edward Armstrong will undertake the obituary of [Sir James] Dewar; gives guidance that Armstrong can arrange with the Society of Chemical Industry to make use of their obituary; also mentions the time constraints with which Armstrong can work with, despite his request for time; brings up the case of [Rodolf] Messel [died 1920], for which an obituary is yet to be written and asks a manuscript by the middle of October. 19 June 1923
