HC Deb 29 February 1864 vol 173 c1251
SIR JOHN HAY

said, he wished to ask the Secretary to the Admiralty, If Captain M'Killop's Flexible Cofferdam has been well reported of to the Admiralty; and, if so, whether it is the intention to develop the invention under Government supervision?

LORD CLARENCE PAGET

replied, that the invention had not yet been sufficiently tried to enable the Admiralty to form any decided opinion. Captain M'Killop, however, had received permission to carry on his experiments at Portsmouth, at his own expense.
