sphere was altered in figure so that the front and hind hemispheres were flattened (so to speak) and “set

The shock of this blow was transmitted to a heavy structure of timber in rear of target, of 16 paces in depth, 
so as to move the whole mass about £ of an inch, as shewn by the displacement of the surrounding sand. 
* Mr Scott Russell's target (29' 10" x 9' 9") was composed of four rows 
of plates, of the following widths, viz :—- 
Upper row, 1' 10§"; second row, V 9|"; third row, l'8f"; and bottom 
row, 2' 10J". 
The plates (all of hammered iron), 4§ ins. thick, were supplied by the 
Admiralty, and had originally been made for the Warrior by the Thames 
Iron Company. 
The total thickness of the target was 8J ins., made up as follows:—a 4§ths 
inch plate, a filling-in piece of 1 in., two 1 in. plates for backing, and two 
f in. plates forming the skin. 
The construction of the target at the rear consisted of two longitudinal 
stringers, 5*5" deep, one above and the other below the port; also two iron 
waterways representing the upper and main decks. The vertical ribs were 
10*5" deep and 21*25" apart; and in order to represent the mode of con¬ 
struction with iron backing as proposed by Mr Scott Russell, a lining of iron 
thick was placed on the upper part of the target (instead of the 3" of teak 
lining of the Warrior target), the remainder of the target being left open in 
order to allow of the examination of the skin. 
The object of the original experiment was to test Mr Scott Russell's system 
of continuous riveting, combined with iron backing instead of wood. 
Projecting riveting was used on one half the target, and flush riveting on 
the other half. There were neither bolts nor rivets in any of the armour 
plates, with the exception of the bottom one on the right side of the target, 
which had four rivets through its centre. 
The target had two port-holes in it.
