The ideas of Mr Reed in reference to construction were adopted, and in one respect it could not be otherwise. The size and power of guns were being increased to overcome the resistance of armour, and this necessitated a smaller number, unless ships were to be much larger. At this time, however, a displacement of 10,000 tons was considered an outside limit. The 'Bellerophon,' begun in 1863, was the first vessel under the new régime.
