 "Ixion" had a combined run of 102 matinee and evening performances before closing on December 26, 1868.The following February Markham began a long run at Niblo's Garden in "Forty Thieves", Thompson's burlesque of "Ali Baba and the Forty Thieves".At the Union Square Theatre (then the Grand Theatre Tammany) in August 1869 she played the central rôle Florizel in "The Queen of Hearts, or Harlequin; the Knave of Hearts, that Stole the Tarts, and the Old Woman Who Lived in the Shoe", a production that at least one "New York Herald" critic considered as foolish as its title.
