Copy letter from Joseph Larmor, to John Henry Poynting, [Fellow of the Royal Society] 'My dear Poynting, It appears that the results in Prof. [Professor] Tiernan's paper which you communicated are all negative and it is suggested that therefore the excessive and voluminous curves which accompany it are not necessary. I think the decision would be facilitated by knowing whether this is so. Very truly yours, J Larmor'. 11 June 1907
