REMARKS. 
16th Decembee, 1864. 
Struck 8 " from top of target; piece of plate 9£" x 8 " broken out and fracture at back of plate measured 16"; 
timber backing in rear of hole carried away; six armour plate bolts and two rivets broken; shot glanced 
upwards and went out to sea. 
Struck lower edge of centre plate between two ribs; through target; crack long from bottom of plate at 2" 
from the edge of the hole, and parallel to its circumference; hole in skin 18" x 12 "; one rib and angle iron 
broken; portion of skin 14" x 8 " driven to rear; seven backing bolts and two rivets broken; piece broken out 
of the bottom of the shot. 
Struck 8 " to the right of last round on a rib ; through target; two holes measured 15" x 8 " in armour plate, 
and 3' 6 " x V 8 " in the skin; 1 ' 9" of rib and angle iron carried away, and 13" timber supporting baulk cut 
through; seven rivets broken. Shot went out to sea. 
Struck top edge of centre plate between two ribs ; through target; centre plate buckled out 1*3" at right end; 
hole in skin 18" x 14"; rib and angle iron cracked, the latter in two places ; one armour plate bolt, four 
backing bolts, and one rivet broken. Shot broke up. 
Struck 12" from bottom of centre plate and 12" to the right of 820; shot broke up and penetrated to a depth of 
9"; crack 0-5" wide across plate passing through indents 819-820; three armour plate bolts, four backing bolts, 
and two rivets broken. 
Struck 7-5" from bottom of upper plate, and 3*5" from a bolt; shot broke up; depth to fragments of shot 5"; 
crack 3" long from bolt hole; centre plate is now out at right end 2-78" at top and 2*18" at bottom; two 
armour plate bolts, one backing bolt, and one rivet broken. 
Struck 105" from bottom of centre plate, between two ribs on uninjured portion of target; penetrated and broke 
up, daylight through target; ripple round hole; hole in skin 18" x 14", and portion of skin 18" x 8 " carried 
away. Two armour plate bolts, (one ordinary and one Major Palliser’s), two backing bolts and one rivet 
broken. The plate was a good deal laminated by the penetration of the shot, and seemed brittle and largely 
crystalline in places. This shot struck a portion of the plate which was entirely secured with Major Palliser’s 
bolts, only one of which was broken. 
Struck at the junction of the centre and lower plates, 10" from last round from centre to centre of holes; 3*5" 
of hole on lower plate; piece of plate 12 " x 10 " between the two plates detached; shot penetrated the target 
and broke up; skin fractured by this and last round over space of 24" x 14"; wood target (14 ft. in rear of 
“Warrior”) penetrated by portions of shot, and very much marked by splinters; no injury to fastenings. 
Struck 17" from bottom of centre plate, on a bolt; nearest point to base of shot from face of target 0*5", deepest 
point 3*5"; shot slightly cracked at base, and inclined to the right after penetration; no damage to dun; 
one rib and angle iron cracked; one armour plate bolt, two backing bolts and one rivet broken, and one 
backing bolt driven out 1". The bolt on which the shot struck (one of Major Palliser’s) was not injured, the 
washer only being a little loosened. 
Struck centre plate 12" above last round, (target weakened by penetration of 943); depth to base of shot 9*5"; 
shot slightly cracked and inclined to the left after penetration; five backing bolts broken; no damage to skin 
or ribs. 
Missed target. 
Struck at vertical junction of two centre plates; shot broke up in hole, depth to fragments of shot 8"; no damage 
to skin, ribs, or fastenings. 
Struck centre plate 16" from the top; depth to base of shot 2 " and 0*5"; shot cracked at the base. Skin slightly 
bulged; two armour plate bolts (one Major Palliser’s, and one ordinary), four backing bolts, and one rivet 
broken. 
Struck 18" from bottom of centre plate, and 12" right of 943; depth to base of shot 2‘25"; shot cracked 
vertically ; one armour plate bolt (Major Palliser’s) and one backing bolt broken. 
Struck the centre plate 15 # 5" from the bottom and 12" right of 947 partly on a rib, shot broke up; target nearly 
penetrated; skm cracked between two ribs and opened 2 ", the fracture, joining that made by rounds 7 , 8 ; no 
damage to fastenings._ 
result was similar to that obtained from Firth's shot fired with full charge, viz. no 
penetration, but considerable damage to skin. 
The result of this experiment shows that while a structure such as the “ Warrior” 
can be penetrated at 200 yds. range with elongated steel shot and shot cast in chill, 
when the form of the head of the latter is elliptical, fired from a 7" rifled gun with 
Jth charges, it is safe from penetration by a spherical shot of the same weight, and 
fired with the same charge from the 100-pr. S.B. gun. 
The target was not penetrated by any of the 7" shot, which struck with a velocity 
equivalent to that produced by the full charge at a range of 1200 yds.; but it 
is probable that had the 1" steel shot been elliptical headed, instead of hemispherical
