REMARKS, 
Struck the plate 2' from top, and 16" from right side. At back, round crystalline fracture; outer circle of 
fracture, 7"; a rim of metal, for half the circumference, thrust out half an inch beyond flat surface of plate. 
Struck the plate 15" below last round, and 22" from right side. At back, similar hole and dimensions to last 
round, only an inner rim or flange thrust out about 1" for half the circumference. 
Struck the plate 3" above and 2to the right of last round; circumference of holes touching. At back, fracture 
breaking into No. 630; similar hole to the first two. 
Struck the plate 12" from bottom, and 9" from right side. At back, dimensions and shape of hole as before, 
only inner flange driven out all round circumference about half an inch. 
Fresh Prate. —Struck 1' 8-5" from top, and 1' 11" from right side. At back, outer diameter of fracture, 7"; 
very clean inner hole. 
Struck 1' below last round, and 0-2" to left. At back, hole a little irregular in form; 7" x 7’5", exterior 
diameter. 
Struck 2-5" above, and 7'5" to the right of last round. At back, exterior diameter, 8" x 6‘5". 
Struck at 6" from bottom, and 5 - 5" from left of plate; ripple only extended round half circumference. At back, 
exterior diameter, 8" x 7". 
At Armstrong Prate. —Struck lower edge, only half circumference on plate. No use for comparison. 
Struck the plate V 1-5" from top, and V 5" from right side. At back, outer diameter, 7". 
At Whitworth Prate.— Struck 1'3" from top, and 18" irom right side. At back, outer diameter of 
fracture 7". 
Struck 4/ from top and V from right side. Outer diameter of fracture, 6'5". 
Fresh Prate. —Struck 2' 6" from top, and V 2*5" from right side. At back, outer diameter, 6-5"; more ragged 
hole ; projecting layers or flanges protruding 1'. 
Struck the plate 1' 2‘5" above, and 3" to right of last round. At the back, exterior diameter of fracture, 
7’3" x 6 - 4" ; rim of metal forced out for 1" beyond the plate. 
Struck railway iron and made a hole 3" in diameter and 3" deep, and shot fell back in front of plate. Damage 
at rear could not be ascertained owing to baulk of timber; bolt head at o' from impact broken off. 
Struck 11" below No. 641. At back, exterior diameter of fracture, 6’6" x 6"; rim of metal projecting three- 
quarters of an inch. 
Fresh Prate. —Struck at 2' 2" from top, at 1' 1" from right side; small crack on face of indent. At back, 
bulge projecting 1", with two vertical cracks 0-3" wide. 
Struck 1' 11" from bottom, and 1' 3" from right side; shot remained in plate, projecting 3*4". At the back, the 
plate was broken through, interior diameter 3" x 2*5", exterior diameter of fracture, 7" x G ' f ; piece of plate, 
measuring 6" x 3", forced back but not detached. 
Fresh Prate. —Struck 2' 3" from top, and V 3" from right side. At back, bulge projecting V", with vertical 
crack 6" long across it, and two horizontal cracks, one 3"'long and 0*5" wide, at middle, the other a narrow one 
at top. 
^Struck at 4 , 5" from top, and 6" from right side of plate. This shot struck a little sideways. At back, only 
slight bulge with vertical crack 6" long. 
Struck 10" from top, and 1' 8" from right side: shot remained in plate, projecting 4*5". At the back five 
radiating cracks, P2" wide, extending over 6" x 5". 
Missed the plate, and struck Captain Inglis’ shield on No. 1 plank. 
Struck 11" from top, and 7" from right side of plate. At back, plate opened 08"x05", with four radiating 
cracks. Plate where struck partly supported by timber. 
Fresh Prate. —Struck railway bar, and broke two bolts. Shot broke in half longitudinally. 
Struck 2' 7" from top, and 6" from left side; ripple only extended round portion of circumference. At back, 
outer diameter, 8" x 6’5". Thrust out inner flanges 1*5". 
Struck 1' 4" from top, and 6" from right side. At back, outer diameter 7*5" x 7". 
Fresh Prate. —Struck 2' 7" from top, and 1' 3" from right side. At back, slight bulge, hardly perceptible ; 
two slight vertical cracks, 1*5" and 1" long, wide. 
Struck 7" above last round. At back, exterior fracture 8" x 7"; half the thickness of the plate driven off, for 
this surface (8" x 7"); a hole through the entire thickness, 2‘5" x 1". 
Struck 1' from bottom, and V 3" from left side. At back, slight bulge, a three-starred small crack, each crack 
about 2‘5" long. 
* This shot had been leaded at the wrong end, and the front part was therefore not case-heardened.
