nor "have they seen cast-iron or steel shot fired through more than two inches 
of iron without the shot itself being broken by the blow ; wrought-iron shot 
have been fired through plates as thick, but though unbroken they have been 
crushed and distorted by the impact. 
The Committee cannot conclude this report without commenting on the 
very inferior character of the 44-in. plates of which this (e Warrior” target 
was composed. They were from Parkhead forge, near Glasgow, and are 
said to be of the number of those made for the “ Black Prince.” They 
were very brittle, and not sufficiently worked; and the measure of their 
inferiority may be recorded by stating that, with the service smooth-bore 
68-pr. at 200 yds. and 16 lbs. of powder, the effect upon the old “ Warrior ” 
target, and upon other good 44-in. plates, w r as an indentation of about 
2*5 in.; whereas the same test upon this target produced an indentation of 
4^05, with considerable damage in the vicinity of the blow. The Com¬ 
mittee deem it right to state that they believe the experiment with the 
Whitworth gun here recorded should be repeated, with as little delay as 
possible, on a target constructed of more satisfactory material. 
The Committee would further recommend that the Whitworth solid shot 
and shell should be tried at an angular target, in order to ascertain the 
effect of homogeneous projectiles on plates placed at different angles to the 
horizon.
