The Lamyet (or Nanjeih) islands are situated to the northeastward of Chinchew bay, the nearest distant about forty miles. The mainland, leaving its usual northeastern direction, runs out due east for above thirty miles, and the first of the Lamyet islands lies off the easternmost point of it. From hence there is an almost uninterrupted series of islands and islets, up to the mouth of the Yangtsze keäng. The Lamyet islands are opposite to the entrance of a deep bay, at the bottom of which is the city of Hinghwa foo, the capital of the most fertile portion of Fuhkeën. This bay, however, has not yet been visited by foreigners. The outermost of the Lamyet islands, named by Ross Ocksou, was found, when passed by the ships of Lord Amherst’s embassy, to be in lat .24° 59' 15" north, lon. 119° 34' 30" east. About thirty miles further to the northward, we pass between an island of peculiar form and the main. This island is named Haetan, the altar of the sea ; in shape it is semicircular, and of nearly equal breadth throughout. A few miles above this island we reach the mouth of the river Min.
