Remarks. 
fThis gun is longer than the Armstrong 
1 12-pr. B. L. gun. 
A shot of this nature has penetrated a 2|" 
plate at an angle of 46°, or a thickness of 
3" of iron, without breaking up. 
C Inside of target much damaged over space 
< of 3' 9" x 2' 3", and splinters of wood and 
(.iron driven through to 20yds. 
Hole in plate 11*5" x 11". 
C Target where struck weakened by previous 
(, firing. 
fin addition to the indent the plate was 
X broken in half. 
Burst after penetrating plate. 
Damage to fastenings of target very great, 
f Shell burst into 14 pieces; pieces of shell, 
X plate, and timber inside target. 
f Shell burst into about 20 pieces, and many 
\ fragments of iron &c. inside target. 
f Shell broke into 2 pieces. A shell of this 
I nature which struck near a hole made by a 
previous shot, penetrated without bursting, 
I although the burster ignited and did con¬ 
siderable damage to the backing, 
f Shell broke into two pieces, and did not 
\ penetrate. 
f The shell burst into 12 pieces ; the target 
| very much shattered. 
["One plate of the target blown off; great 
J damage to fastenings; a large number of 
] splinters of iron and wood blown through ; 
Ijshell burst into 4 pieces._
