Mr Kent, whose surprising exploits have attracted so much attention in Liverpool and other places where he has appeared before the public, arrived here on Sunday evening by the Steam Packet Waterloo.
On the packet reaching Ringsend, he launched and mounted his marine velocipede, and proceeded before the packet up to Sir John Rogerson’s-quay, where he was loudly cheered by the spectators on shore.
We understand it is his intention to exhibit his apparatus here, should he meet with public encouragement previously to his departure for London.

Walking on water
On Friday a prodigious crowd, upwards of 30000 people, assembled on the banks of the Clyde, to witness the performance of Mt Keat [sic], who had announced his intention of riding on his aquatic velocipede, from Rutherglen-bridge to the Wooden-bridge. He started precisely at a quarter before three o’clock, and reached the Wooden-bridge at a quarter past three. He amused himself with loading and discharging a fowling-piece as he sailed along. Several porters were stationed at the different entrances of the Green with subscription-boxes. The machine consists of three oval tin cases united by iron rods to support a sort of saddle, upon which the artist sits, at such a height as is suitable for using his feet to give the requisite impulse. The weight of the whole does not exceed 14 lbs.
