The Musical Union, an establishment which gives proof of the
progress of gonad and solid taste in fashionable society, had its first meeting of the gessoes' at Willis's Rooms on Tuesday. The performance, directed as usual by Mr. Ella, consisted entirely of three great instrumental pieces—a quartet of Mozart, a quintet of Beethoven, and a pianoforte trio of Men- delssphn; and this severe music was listened to by a large assemblage of ladiet.and gentlemen, with the utmost attention and every appearance of intelligent pleasure. Among the performers, the only stranger was Herr Otto Goldschmidt, a young pianist, a pupil of Mendelssohn; who played his instructor's music in a manner which showed a congenial spirit.
