Sea MORTARS, are those which are fixed in bomb vessels for bombarding places by sea: and as they are generally fired at a much greater distance than that which is required by land, they are made somewhat
longer and much heavier than the land mortars. The following table exhibits the weight of the sea mortars and shells, and also of their full charges.
