This is probably a silly question, but I have looked through the posts thus far and haven't seen anything on this subject.

The word "quiz" is used several times in the first 7 chapters, and it is not used in the modern sense (ie. quick test) of the word (in my opinion anyway)... Can someone please clarify?

From Ch 4:
Their conversation turned upon those subjects, of which the free discussion has generally much to do in perfecting a sudden intimacy between two young ladies: such as dress, balls, flirtations, and quizzes. Miss Thorpe, however, being four years older than Miss Morland, and at least four years better informed, had a very decided advantage in discussing such points; she could compare the balls of Bath with those of Tunbridge, its fashions with the fashions of London; could rectify the opinions of her new friend in many articles of tasteful attire; could discover a flirtation between any gentleman and lady who only smiled on each other; and point out a quiz through the thickness of a crowd.
