or Flotsom**, goods that by shipwreck are lost, and floating upon the sea; which, with jetson and lagan, are generally given to the lord admiral: but this is the case only where the owners of such goods are not known. And here it is to be observed that jetson signifies any thing that is cast out of a ship when in danger, and afterwards is beat on the shore by the water, notwithstanding which the ship perishes. Lagan is where heavy goods are thrown overboard, before the wreck of the ship, and sink to the bottom of the sea.
