Mr. Langbaine has preserved part of the general prologue to her plays, which we shall insert as a specimen of her versification: 

  But noble readers, do not think my plays
  Are such as have been writ in former days;
  As Johnson, Shakespear, Beaumont, Fletcher writ,
  Mine want their learning, reading, language, wit. 
  The Latin phrases, I could never tell,
  But Johnson could, which made him write so well. 
  Greek, Latin poets, I could never read,
  Nor their historians, but our English Speed: 
  I could not steal their wit, nor plots out-take;
  All my plays plots, my own poor brain did make. 
  From Plutarch’s story, I ne’er took a plot,
  Nor from romances, nor from Don Quixote.
