As she improved rapidly in her acting, she gained the praise of critics and popular applause. Returning to London, she leased the Prince's theatre, and appeared on 20 Jan., 1885, in the title rôle of an English version of "La Princesse Georges," by Alexander Dumas the younger, on 11 Feb. as Lady Teazle, and on 6 April as Lady Ormonde in "Peril."
