HC Deb 17 March 1871 vol 205 c176

asked the First Lord of the Admiralty, Whether any, and if so what, steps have been taken to practically test Captain Moncrieff's plan for working ships-guns by means of hydraulic pressure?


This matter, its advantages and disadvantages, as compared with the system now adopted, has been considered by the Admiralty, and, so far, it has not been thought desirable to put it to a practical test, as preliminary difficulties have been raised.
