Mr. Charles Dickens and Mr. George Dolby arrived in the city yesterday afternoon and took quarters at the Tift House.  In the evening they quietly visited the Metropolitan Theatre, and took possession of a private box.  Mr. Dolby presented a good looking front in the box, but Mr. Dickens allowed the curtains to conceal his form and face from the audience, leaving him visible only to the actors on the stage and to those in the opposite box.  The particular feature of the performance which excited Mr. Dickens and Mr. Dolby was the "Sailor's Hornpipe" by La Petit Susie- a bewitching little danseuse of five summers.  This they applauded with a will.  We confess we had watched for the effect he appearance of the pretty little dancer would have on the face of Mr. Dickens, for if there is one thing more more universally accepted than another in regard to him, it is that he loves children.  We were not disappointed, for no sooner had the little elf commenced to respond to the music, then there became visible in his expressive face, both pleasure and approval.  Mr. Dolby shared with Mr. Dickens in a good natured recognition of the bright child's talents, which are really remarkable, and applauded her in her dance at it's close. Susie is pretty, intelligent, wonderfully imitative, and has a very unusual appreciation of time, and no lover of children would hesitate to fall in love with her.  We do not know what would become of Henry Ward Beecher, if her were once to see her in her dance; but we are satisfied on one point, and that is that the organ of Philoprogenitiveness is exceedingly well developed in the heads of Mr. Dickens and Mr. Dolby.
