HC Deb 20 September 1909 vol 11 c11
Mr. GEORGE ROBERTS

asked the Postmaster-General if his attention had been directed to the Kelway sound-locating system; whether he had caused inquiries to be made into the effectiveness of that system and, if so, with what result?

Mr. BUXTON

I have no knowledge of the system beyond what Mr. Kelway has himself furnished; but I am offering him a licence, subject to certain necessary conditions.
