a sea-port town of Hampshire in England. It is commodiously seated on an arm of the sea; is a place of good trade, and well inhabited. It is surrounded by walls and several watch-towers, and had a strong castle to defend the harbour, now in ruins. It is a corporation and a county of itself, with the title of an earldom, and sends two members to parliament. W. Long. 1. 26. N. Lat. 50. 55.
