HC Deb 14 March 1905 vol 142 c1360
SIR THOMAS DEWAR (Tower Hamlets, St. George's)

To ask the Postmaster-General whether arrangements can be made to ventilate public telephone call-boxes.

(Answered by Lord Stanley.) The telephone silence boxes used by the Post Office are already ventilated as thoroughly as is consistent with the privacy of conversations and the exclusion of outside noise. The point has received a good deal of attention, and the system adopted is, it is thought, the best that can be devised.
