"The Cerberus has two of these revolving iron turrets, each of which has two guns. In our engraving one of these is fully shown, and the other is just visible in the background. The guns are of 10 inch bore, and muzzle loaders. They throw a shot or shell of 400 lb. (175 kg) weight, and weigh 18 tons each. The charge of powder ranges from 45 lb. to 60 lb., and the range of shot is about 4 miles. Good execution can be done at a range of 3½ miles."
