Letter from H M [Hector Munro] Macdonald, 52 College Bounds, Aberdeen, to [Joseph] Larmor The portrait of William Davidson Niven arrived and the reproduction is done. Subscribers will have viewed their copies in a few days. He will let Larmor know how [financial] matters stand once he has Annan's account. He asks if Larmor intends to accept the British Association invitation to go to Australia, as this might help him to make up his own mind. He saw [Horace] Lamb in Manchester, who seemed recovered. He heard some criticism of Larmor's Adams Prize there. He has been struggling with a paper by [Sydney] Chapman sent from the Royal [Society] and has written his opinion at length ['On the diurnal variations of the earth's magnetism produced by the Moon and Sun']. He wishes that before going to print, men would lock their paper in a box for a few months then read it 'in cold blood', thinking it would save refereeing work. Niven is better but far from fit. 22 May 1913
