Pride and Prejudice (Pg. 9)

4. “... And the two fifth with Jane again, and the two sixth with Lizzy, and the Boulanger.” (Page 9):
The Boulanger was an English Country Dance . The dance reached its popularity peak in Austen's lifetime. The Boulanger was a "mixer" dance; it was repetitive and moved so partners were changed and every dancer had the opportunity to dance with every partner of the opposite sex at least once. Austen most likely referenced this dance because she was most familiar with it. According to the Georgian Index, Austen often used dances as parallels to marriage. This may be connected to the relationship between Lizzy and Darcy. When they dance together, they struggle for conversation, just as they struggle to acknowledge their love for each other.
