Naval advisers came and went. They included, during the period 1865-1885, the present British admirals Tracy and Hopkins, the eminent French naval architect M. Bertin, and finally Captain Ingles, R.N., of whom more will be found in the Appendix.

| Material | Composite. |
| Length | 213 ft. |
| Beam | 41 ft. |
| Draught (extreme) | 19 ft. |

BATTLE OF HAKODATE.
The horse-power was 975 nominal, the speed 9 knots. She was single-screwed, and carried 350 tons of coal. Like all the early sea-going ironclads, she had a 4½-in. iron armour belt, and 4 inches over the amidship battery. The heaviest gun was carried in the bow on a pivot. The ship still exists as a hulk. She did not reach Japan till the Civil War was over.
