This may truly be called a remarkable plate. No shot got through 
except Pound 5, and it was originally intended only to fire three 
rounds at the plate, so much of it being what is usually cut off as 
waste. It stood the first three rounds so well though, that the two 
others were fired. 
Pound 1.—The shell broke up; the penetration being slight, and 
only a few cracks being formed. 
Pound 2.—The Palliser shot was shivered, and splashed on the face; 
the indentation being only *85 inch. 
Pound 3.—This shell also broke up, but rather a larger piece of 
steel was splintered out towards the slag end of the plate. 
Round 4.—The shell broke, leaving its head in the plate and an 
indent of two inches; one crack made by this round was through at 
the edge.
