Weichsel, the brother of Mrs. Billington, played in public with his sister, when she was _six_ years old, and himself a year older—their instruments being the violin and the pianoforte.—Balfe, the singer and composer, made a kind of _début_ as a juvenile violin-player (according to the _Harmonicon_) at a theatrical benefit.—Two Hungarian boys, of the name of Ebner, one ten and the other eleven, played some of Mayseder’s difficult variations at a Concert at Berlin, in 1823.—A boy of twelve years of age, named Khayll, pupil of Jansa, introduced by Moscheles at a Concert at Vienna in 1827, played some admirable variations on the violin, in which he displayed an ease and solidity far beyond his years, and a great knowledge of his instrument.—At Limberg, in 1831, Apollinarino Conski, _five_ years old, surprised all hearers by his execution of a concerto of Maurer’s; and the son of this last-named Artist, at the age of twelve, performed in the same year some of Mayseder’s variations, at his father’s Concerts at Berlin. At Stutgardt, in 1831, the brothers Eickhorn, the elder _nine_, and the younger _seven_ years of age, gave a Concert at one of the saloons, and astonished not only the public in general, but the connoisseurs, by their early proficiency on that most difficult of instruments here under notice. The elder played variations by Mayseder and Rode, and a potpourri with his younger brother, composed by Jacobi—and some variations of Kummer’s. In various towns of Switzerland, during the same year, the four brothers Koella, of Zurich, gave Concerts with great success. These boys were then respectively twelve, ten, nine, and seven years of age—“small by degrees, and beautifully less.” The elder played the violin and violoncello with great spirit and power; the third was a good tenor-player; and the youngest executed concertos of Viotti’s! Their quartett-playing, however, was their strongest point. Dr. Crotch, when about _five_ years old, was capable of fiddling, and after a fashion, too, by no means common to others—that is to say, _left-handed_. _Fiddlers’ Tricks._—In 1731, a Concert was announced at Hickford’s room, for the benefit of Signor Castrucci, _first violin of the Opera_, who, as the advertisement stated, was to play, amongst other pieces, a solo, in which he would execute “_twenty-four_” notes with one bow.” On the following day, this advertisement was burlesqued by another, in which was promised a solo by the _last violin of Goodman’s Fields’ Playhouse_, who would perform _twenty-five_ notes with one bow. Such a feat as either of these, would, in our own days, be nothing at all.
