We are glad to see that another ship has been

built on the prin- ciple of the Castalia,'—i.e., the twin-ship principle,—and one which can count on more than double the speed. The Castalia was admirable for its steadiness and its immunity from sea-sickness, but then it went so slowly that your milder sufferings were twice as long in duration. Messrs. Leslie and Co. have now built a double ship called the Express,' which draws less water than the Castalia,' and attains more than double the speed. She goes already fourteen and a half knots an hour,—i.e., sixteen miles and three-quarters,—and she is expected to go still better, as her hull is foul. For all Channel passengers liable to sea-sickness, this is good news.
