Copy letter from Robert William Frederick Harrison, to Louis Brennan, Woodlands, Gillingham, Chatham 'Soirée Dear Sir, At a recent meeting of the Soirée Exhibits Committee it was suggested that you might be willing to exhibit at the forthcoming Soirée of the Society, on May 6th., your mono-rail waggon. It was thought that it would constitute a most attractive exhibit. Perhaps you will kindly let me know your views. I am, faithfully yours, Assistant Secretary R.S. [Royal Society]'. 25 March 1907
