Gurry

Among those in general use that have drawn the attention of Europeans living in India, are the alloys for the gurry, and the Biddery ware. The gurry is a disk of a cubit and upwards in diameter, about half an inch in thickness in the centre, but decreasing toward the circumference, where it is scarcely more than 1/4 of an inch. It is used to mark the divisions of time, by striking it with a wooden mallet.

It is a small brass basin, about four inches in diameter, made thin enough to float on the water, with a hole in the bottom which admits as much as to fill it exactly in one gurry, or twenty-two and a half minutes. The sinking, therefore, of the vessel, is the signal for striking the gurry, and warning the inhabitants.
