Copy letter from Robert William Frederick Harrison, to Messrs Drake & Gorham, 66 Victoria Street, S.W. The Messrs may already have heard through Mr Seaman that it has been decided to postpone any general re-organization of the wiring of the Society's rooms until the next session but certain re-arrangements of switches are considered necessary for the security of the building. The latter works are to be undertaken at once. Encloses a specification of the work [not enclosed], and asks for an estimate on the understanding that the work is completed by 14th November. The work is to be carried out to the satisfaction of Professor [William Edward] Ayrton or his representative. 2 November 1898
