Mean result of 600-pounder firing, at Shoeburyness, 18th July, 

 1864:— 



Weight of shot (cast iron). I Charge. 1 Elevation. I Range. 



513 lbs. I 70 lbs. | 20° 9' 4" | 7372 yds. 15 ft. 



The above Tables have been kindly sent to me by an officer who was 

 present. 



The Marquis of Hartington, Under Secretary of War, has stated in 

 the House of Commons that the Armstrong 600-pounder is the best gun 

 the country has as yet got from any inventor, which has been proved by 

 the wonderful accuracy of range and great power exhibited by this gun. 

 Undoubtedly it is the best of all the Armstrong guns, their principal 

 faults arising in a great measure from the fact of their being breech- 

 loaders — a species of gun not to be depended on with any degree of 

 confidence. 



Whether, indeed, such a gun as the 600-pounder could be used on 

 board the " Royal Sovereign" or " Warrior" is doubtful, the ship roll- 

 ing at an angle, say of 1 7°, would render the weight on the vertical line 

 of oscillation so great as to strain the ship, and affect her stability in a 

 most dangerous degree. In such a case forts would possess a manifest 

 advantage over ships if armed with such guns ; while if seaports pos- 

 sessed flat-bottomed barges, propelled by a screw, carrying even one 

 600-pounder, any part of the coast could be easily reached, and rendered 

 secure against an enemy, from the extreme range and power of the 

 gun.
