a considerable city of Portugal, seated near the head of a small gulf formed by the tide at the mouth of the river Vouga. This river forms a small haven with a bar, over which vessels may pass that do not draw above eight or nine feet water. The city stands in a long plain, well watered, and very fertile. This plain is nine miles broad, from Porto to Coimbro; and is bounded on the east by a chain of mountains called Sara d'Alcoba, which reach from the one town to the other. Near this city there is salt made in sufficient quantity to serve two or three provinces. Here is a remarkable nunnery, where none are received but the daughters of the ancient nobility. The inhabitants of Aveiro have the singular privilege, that no stranger whatever can pass a night there without leave of the magistrate. W. Long. 9. 8. N. Lat. 40. 30.
