| Description | Harrison conveys the decision of the Soiree Committee to request that Brennan give a demonstration of his mono-rail invention at the Ladies' Soiree on 19 June. Should he agree, they will discuss details, but the Committee suggest that he show one demonstration of sufficient length, rather than placing other exhibits between two of Brennan's. He also communicates the request of the President that Brennan show him and other Officers of the Royal Society his working model at a convenient quiet moment in the afternoon before the Soiree, possibly while the Press people are viewing the 'ordinary' exhibits. |
