HC Deb 05 August 1875 vol 226 cc560-1
MR. HANBURY-TRACY

asked the Surveyor General of Ordnance, Whether the vents of heavy muzzle-loading guns cannot now be rendered as enduring as necessary by the application of a simple invention for preventing all escape of gas through the vent, and consequent corrosion thereof?

LORD EUSTACE CECIL

Sir, trials are now in progress with this object, and it is to be hoped that the plan under trial will greatly diminish the corrosion consequent on the escape of gas through the vent.
