The last new domestic melodrama at the Adelphi, Mary Melvyn,
or the Marriage of Interest, is by Mr. FITZBALL j who appears to have taken the story from that sink of slang, villany, and horrors, " Les Mysteres de Paris," by EUGENE SUE. Murdered by Mistake, or Caught in his own Trap, would have been a fit appellation for the Adelphi piece ; since its catastrophe is the shooting of a disagreeable husband instead of the man be was jealous of, whom he had hired an assassin to murder. LYON personated the vulgar, tyrannical husband, irritated by his wife's passive obedience and infuriated by the appear- ance of her once favoured suitor, very forcibly ; but his acting wants a little quietude to relieve its incessant vehemence and boisterousness : his look of frantic exultation when he conceived the idea of getting his rival murdered was appalling. Mrs. YATES, the wife, has only to endure ; which she does gracefully and pathetically. BEDFORD, the murderer, looks a hardened and desperate ruffian, to whom any deed of violence would be only a matter of business ; and 0. Salim plays the stale part of a tender-hearted and white-headed old sailor, with fresh- ness, and without being maudlin.
