HC Deb 28 July 1930 vol 242 c33
52. Sir W. DAVISON

asked the First Commissioner of Works when the existing system of ventilation of the House of Commons was first installed; and when any alteration or improvement was last effected and in what respect?

Mr. LANSBURY

The existing system of ventilation in the House of Commons was first installed in 1854 and modified in 1892. A minor alteration was recently effected whereby the air inlets beneath the benches. have been covered with canvas.

Sir W. DAVISON

Have any of the streptococci been forcibly fed since this recent alteration; and was the result the same as before when they were fed on broth for some months and very largely propagated?

Mr. LANSBURY

The hon. Gentleman had better give me notice of these questions.
