were probably made in France or Germany about the year 1800. The invention of the nail-violin is attributed to a German of the name of Wilde, who lived in St. Petersburg about the middle of the eighteenth century. A hurdy-gurdy (French, _vielle_), made by Pagot at Jenzat, a small town near Orleans, about the year 1840. Carved head. Six tuning-pegs at the top, and one at the tail-piece. This hurdy-gurdy is of the kind which the French call _vielle en luth_, because its body is shaped like that of the lute. The other kind, which has indentations at the sides resembling those of the guitar, is called _vielle en guitare_. Organ hurdy-gurdy, or _vielle organisÈe_, made by a Frenchman residing in London during the middle of the eighteenth century. This curious instrument, which was formerly also known in England, where it was called _flute-cymbal_, consists of a hurdy-gurdy combined with a small organ of two stops, and it is so contrived as to allow the hurdy-gurdy or the organ to be used each separately, or both combined, at the pleasure of the performer. Some portions of it have been restored in the present century. Clavichord, generally called in German _Clavier_. Made in Einbeck, near Hanover, about the year 1800. Clavichord, made in Thuringia. Clavichord, made by the celebrated manufacturer, Barthold Fritz, in Brunswick, in the year 1751; ornamented with painting and engraving. Harpsichord, inscribed "Jacobus Kirkman, Londini, fecit 1772." The case is of walnut, inlaid with tulip-wood. Carved legs representing eagle's claws grasping a ball. With two keyboards, constituting a "double harpsichord," as it used to be called in England. The woodwork about the keyboards is ornamented with designs in marquetry of various coloured woods. This harpsichord has six stops and two pedals, and is provided with a Venetian swell. Jacobus Kirkman, having obtained an order from King George III. to produce a fine harpsichord intended as a present for Queen Charlotte, made--as manufacturers under such circumstances not unfrequently do--two harpsichords exactly alike, viz., one for Queen Charlotte, and the present one, which was bought by John Bacon, the famous sculptor, after whose death it came into the possession of Dr. Sclatter, priest-vicar of Exeter Cathedral, who had it for nearly half-a-century, and after whose death it was sold at a sale of his effects. Harpsichord with two keyboards, six stops, and two pedals. Inscribed "Jacobus et Abraham Kirkman, fecerunt 1773." The case is of mahogany; the wood near the keyboards is walnut, inlaid with tulip-wood and a tesselated border of various coloured woods. Only the lute-stop has jacks with crow-quills; the jacks of the other stops are provided with small pieces of prepared leather instead of quills. The variety in the colour of sound thereby obtained is very effective. This instrument probably exhibits the highest degree of perfection which was ever attained in the construction of the harpsichord, in so far as
