Mary's education

[Donna McCreary]

The May 6, 1838 issue of The Lexington Intelligencer contained an announcement for Madame Mentelle's boarding school stating the students would receive "a truly useful and solid English education in all of its branches."

Exactly what is an English education and all of its branches?
We know the only language spoken at the school was French. While a student, Mary performed in at least one French play, studied music and learned to dance.
