An addition has been made to the vocal company of

the Princess's Theatre, in the person of Herr Mengis, a performer of some ability, who appeared on Wednesday in the character of Franz in Flotow's opera of Leoline. He is a heavily-built man, with a face to match; but his action is not without fire, nor are his features without expression. He sings with German purity and simplicity of style; and his voice is full and mellow, though defective in power in its lowest notes; for which reason he failed to give effect to some passages of the music, written for a very deep bass. Miss Poole played the part of Leoline for the first time, very prettily; ana the effect of the opera was much improved by the double change of cast.
