51. Lieut.-Colonel Shaw’s Muzzle-pivoting Carriage. 
In a note which will be found at p. 260, Yol. V. of the “ Proceedings ” of the 
E.A. Institution, Lieut.-Colonel Shaw states, “ that although one of his wrought- 
iron muzzle-pivoting carriages had been under trial on board H.M.S. “ Prince 
Albert,” for nearly a year, he had not been able to obtain any official information 
as to its efficiency or otherwise.” 
The following information has since been published.* 
Captain Foley, of H.M.S. ** Cambridge,” reports that ,e after having given the 
iron muzzle-pivoting carriage on Lieut.-Colonel Shaw’s design for 12-ton guns, on 
board the * Prince Albert,’ a good fair trial, with continuous battering charges at 
high elevations, he is of opinion that it is on a most excellent principle, and better 
adapted for working in a turret than the other iron carriages (on the single plate 
system of Boyal Carriage Department make, for 12-ton guns, mounted on wood 
shifting platforms made in Woolwich Dockyard on Captain Coles’ system), on 
board that ship, inasmuch as extreme elevations are easily obtained in three to 
five minutes; whereas, with the carriages in the other turrets, to give the same 
amount of elevation would take three quarters of an hour to lower the platform. 
He considers this of the greatest importance. 
“ The porthole in the turret, in which the muzzle-pivoting carriage is used, 
being very much smaller than the other turrets, is also a great feature in its utility, 
by lessening the chance of a shot entering the turret. 
** In returning the above report on the trial of Lieut.-Colonel Shaw’s muzzle- 
pivoting carriage, the O. S. Committee consider the result as highly satisfactory to 
the construction, as well as to the principle of muzzle-pivoting.” 
The number of rounds fired from the 9-inch rifled muzzle-loading gun mounted 
on the above-mentioned carriage, on board the “Prince Albert,” were as follows t —
