“ Ethnography.—The Annamese, or, to use the native term, the Giao-chi, are the predominant people not only in Annam but in the lowland and cultivated parts of Tongking and in Cochin-China and southern Cambodia. According to their own annals and traditions they once inhabited southern China, a theory which is confirmed by many of their habits and physical characteristics; the race has, however, been modified by crossings with the Chams and other of the previous inhabitants of Indo-China.The Annamese is the worst-built and ugliest of all the Indo-Chinese who belong to the Mongolian race. ”
