The same usage still prevails among the vulgar as in the phrases, ‘black Irish’, ‘black Dutch’, describing certain well known types of Celts and Teutons (Hollanders, probably), differing widely from the prevailing type of either race in respect of their black eyes and hair, and gypsy-like, tawny complexions.
