Letter from J. H. Owen Harries, Shirley, Old [Road], Frinton on Sea, Essex, to [Alan Archibald] Campbell Swinton [Esquire], 40 Chester Square, London, S. W. 1. Informs that Oliver Lodge referred him to Swinton in response to his enquiry, as one who might possibly consent to be kind enough to give his opinion on a method of television employing cathode rays, among other parts. Formally introduces himself and his reasons for his request. 14 May 1929
