"What a delightful quadrille we are having!" she said enthusiastically as she passed him. "Delightful!" he acquiesced, with a sudden leap at his heart, and forthwith he resolved to engage her for the next dance as soon as ever he should be at liberty.
-- Ross Neil, "The Heir Expectant," 1870
Quadrille entered English in the 1700s from the Latin quadra meaning "square."
