Miss Marshall won golden opinions by her charming delivery of Gluck’s “ Che faro,” and Miss Birch, sang the superb “Ah perfido” of Beethoven better than I have ever heard it sung, except by Malibran; in the ranting air (with violin obligato) from Paer’s dull opera of Griselda, Miss Birch was no less successful, but, from the inferior nature of the composition, much less agreeable.
