Copy letter from Herbert Rix, to the Secretary, London Electric Supply Corporation, 3 Adelphi Terrace, W.C. The President and Council of the Royal Society are very anxious to show Professor Elihu Thomson's experiments [at the Soirée] which Dr Fleming showed at the Society of Arts a fortnight ago. Fleming has undertaken to do this provided the Directors of the Electric Supply Corporation will supply the Society with current for that evening. 30 May 1890
