The Navy in 1840.

found that the shot nearest the charge penetrated 29 in., while the one furthest from the charge penetrated 42 in. There were three types of mortars then in the sea service, the 13 in. of 100 cwt. and 81 cwt, and the 10 in. of 52 cwt. They had a range of about 4000 yards, with an elevation of 45°, and their object was, in a bombardment, to crush buildings and penetrate magazines. Their transport by sea was not difficult or costly, and it was considered that a fleet should be provided with vessels for this service. The introduction of shells was slow. The old prejudice in favour of solid shot was not easily overcome. The latter were said to be more accurate, and to have greater range and penetration than hollow shell. Objections were also raised to putting too many shell guns in ships, on account of the danger of accidental explosions.

Another argument used against the introduction of these projectiles was their cost. Sir Howard Douglas, in his work on Naval Gunnery, says: 'The expense of shell equipment is enormous. The cost of every 8-inch shell in box is 11s. 6d. Each one fired costs 17s. 4¾d.' The 17s. 4¾d. included the powder, the amount of which was 10 lbs. What would Sir Howard have said if told that fifty years later the cost of a single round from guns mounted in battle ships would range from £150 to £200? How insignificant seems the 68-pound shot, propelled by 16 lbs. of powder, beside the 1800-lb. projectile of to-day. But as regards shell, it required the incident of Sinope a few years later to demonstrate the terrible effect of shell fire upon wooden ships, and
