Mr.
Lloyd, the chief engineer of the Navy, conducted the investigation, and reported most favourably as to the manner of her performance.

Yet several years elapsed before the screw was introduced into the service.
In 1840 the Archimedes was placed at the disposal of Captain Chappell, of the Royal Navy, who, accompanied by Mr.Smith, visited every principal port in Great Britain.

She was thus seen by shipowners, marine engineers, and shipbuilders in every part of the kingdom.

They regarded her with wonder and admiration; yet the new mode of navigation was not speedily adopted.

The paddle-wheel still held its own.
