Copy letter from Robert William Frederick Harrison, to Professor Sydney Howard Vines, Fellow of the Royal Society In reply to Vines' card, Harrison hopes to send him a copy of [Henry Horatio] Dixon & [John] Joly's paper tomorrow. Some of the manuscript is difficult to decipher which has retarded the work, but it is very nearly completed. Harrison presumes Vines has ascertained that the authors of the paper have no objection to Vines taking a copy of the unpublished portion. The Secretaries directed Harrison to satisfy himself on this point. 2 December 1896
