I think it probable that this inscription was cut by the same European, 
I believe a Prussian Officer, who some 40 years ago was employed by the 
Porte to mount the guns at the Dardanelles on modern carriages.

each of the pieces enumerated in Table I. has one like it; as the more 
important data are embodied in that table they need not all be repeated, but 
the most ancient, which is on three guns of the date 1521, is engraved on 
Plate VII. 
The following extracts from the log of II.M.S. <c Terrible,” Captain 
Commerel, C.B. details the measures taken by that officer for the em¬ 
barkation of this ponderous piece of artillery, and the manner in which he 
unscrewed the two parts. 
Jan. 10, 1868. Commenced rigging a pair of sheers outwards, which 
consisted of two two-decker topsails, with topping lifts of stream chain over 
lower mast-head and into the main deck port on opposite side. 
The same day commenced rigging similar sheers on those topping lifts, two 
parts of an eighth-inch hawser, set taut to the stream anchor, backed with 
timber, &c. 
Jan. 16. Hoisted out 6 J ton gun, and landed it in paddle box boat. 
Jan. 17. Hoisted out 12-ton gun, and landed it in same boat. 
Jan. 18. Hoisted in the shorter half of the large gun, and the afternoon the 
longer half. 
The fall used was 6£, the blocks, threefold, 24 each. 
It was found necessary to unscrew the gun; this was performed by the engineers 
of the “ Terrible,” by means of the lever jacks of ten tons, and capstan bars made 
to fit the holes cast in the gun, a power of nearly 40 tons was used for this 
purpose. 
The gear all closed remarkably well, not a rope yarn strained or spar sprung. 
The gear lay on the open beach at Chanak, and was very exposed to the 
prevailing winds. Three days would have sufficed for the operation if weather had 
permitted. 
It is remarkable that Baron de TotPs description of the enorme perrier 
dont le houlet en marbre pesait 1100 livres , like that of Dr Pococke, 
applies to this gun, and to no other now existing. “ Cette piece ” he says, 
“fondue en bronze sous le regne d * Amurat, etait composee de deux morceaux 
reunis par tine vis, a Vendroit que separe la cliambre de la volee, comme un 
pistolet a l’Anglaise.” He relates how he loaded it with 330 lbs. of powder 
and discharged it. He observed the shot break into three pieces about 
600 yds. from the gun, and these pieces crossed the Dardanelles, leaving 
the surface in a foam where they struck, and went bounding up the opposite 
shore. He is very vague, or rather says almost nothing, about the other 
pieces, and his authority for the date of this piece cannot be accepted. 
Amurath, or Murad II. was the father of Muhammad; he was the first to 
employ artillery, but it is impossible to transfer to him the credit which
