Do we wish to banish all music from the busy haunts of men? By no means. Good music is sometimes emitted from our pavements--the kerb sends forth here and there, and now and then, sounds not unworthy of the best appointed orchestra. Where these superior street performers received their musical education it is not our business to inquire; but their arrangements of some of the most popular opera music, show that their training has been strictly professional. Quintette, Sestette, and Septette bands of brass and string are occasionally heard in the open street, whose performances show that the pieces have been regularly scored and rigidly rehearsed. "Tune, time, and distance" are excellently kept; the pianos and fortes are admirably colored--there is no vamping of basses; no "fudging" of difficult passages. We look upon such players as musical missionaries who purvey the best music from the opera houses and from the saloons of the nobility to the general public, to the improvement of its musical taste. But where even these choice _pavé_ professionists have us at a disadvantage is in their discoursing their excellent music at precisely the times when we do _not_ want the sounds of the charmer, charm he never so wisely. The habitant of the "quiet neighborhood," fond as he is of _Casta Diva_ or the _Rosen Waltz_, would rather not be indulged with them just as he is commencing to study a complicated brief, or while he is computing the draft of a difficult survey. When he wants music he likes to go to it; he never wants it to come to him. [From Dickens's Household Words.] MISTAKES IN PERSONAL IDENTITY. There is no kind of evidence more infirm in its nature and against which jurymen on legal trials should be more on their guard, than that involving identity of person. The number of persons who resemble each other is not inconsiderable in itself; but the number is very large of persons who, though very distinguishable when standing side by side, are yet sufficiently alike to deceive those who are without the means of immediate comparison.
