Letter from W D [William Davidson] Niven, Eastburn, Sidcup, to [Joseph] Larmor He was sorry to hear that Larmor was 'knocked up' by work and he must be looking forward to a break in Parliamentary duties. He thinks that some of this work should be devolved to others, and that another trip to Madeira should have been the thing, although that would be impossible in present circumstances. 31 January 1916
