The archives of the arsenal of Paris mention a twelve-pounder wrought-iron cannon, weighing sistccn hundred pounds, made in this way in 1753. Thcrc are to be sect at the mnscum of the artillery school of Strasbourg, four wrought-iron pieces, wcigliing from ninety to one hundred pounds ; one OS which bears the date 1601. At the commencement of the last century, new attempts were made in France to introduce the manufacture of wrought-iron cannon by a new process. It was proposed to envelope them with solid bands. A very high price was asked for cannon made in this way, under the
