Copy letter from Joseph Larmor, to Dr William Napier Shaw, Fellow of the Royal Society It can be seen that the actual information by itself given in Captain Lyons' paper renders it desirable to publish it. The record[?] will be put in the Archives for reference. Advice on the amount of diagrams is needed. Asks if Shaw can reduce them to three, and give a reference to the place where they are already engraved and published[?]. Larmor wishes more people would take an interest in this subject. 20 December 1904
