In this design the surface exposed to hostile fire is diminished by con- 

 structing the vessel with a central fort, armour plated all round, an armoured 

 deck under water, and dividing the space above this armoured deck for a 

 height of six feet into water-tight compartments, which would be filled with 

 fuel or water when going into action. She is intended to carry both turret 

 and broadside guns, and might be armed with a submarine weapon. 



2 14 7 ad. Three diagrams of new type of War Ships, 



designed by Michael Scott in 1870, and published in 1871. 



Michael Scott, London. 



In this design there is a central fort, armour plated all round ; an armoured 

 deck under water sloping downwards towards the bow, so as to prevent the 

 vessel from being raked in a seaway, and strengthening the ramming beak. 

 The ship is intended to carry sail, her turrets to be placed abreast, and also 

 to carry broadside guns. 



Some of the most important features in these designs have been adopted 

 in the most modern war ships.
