constructed like the theorbo, but having a flat back, was evidently often strung in France with catgut instead of wire, and played with the fingers like the theorbo. It is probably the instrument which in some old French books is called _pandore_. It has sixteen strings. A French bijuga cither of the eighteenth century, inlaid with mother-of-pearl, ivory and ebony. A fine specimen. An English bijuga cither, eighteenth century. A German bijuga cither (or Grosszither, as it used to be called in Germany), sixteenth century. With seventeen wire-strings. This old instrument is very beautiful in shape, and has a remarkably picturesque rose in the middle of the sound-board. Two Neapolitan mandolinos, inlaid with designs in mother-of-pearl tortoise-shell and ivory. One of these handsome instruments bears the inscription "Januarius Vinaccio fecit, Neapoli, in Rio Catalana, A. Domini 1776." A beautiful Neapolitan mandolino in its old Italian case. Inside the instrument is the inscription "Vincentius Vinaccio fecit, Neapoli, Sito Nella Calata de Spitalletto, A. D. 1785." A Milanese mandolino, dating from about the year 1700. Rosewood, inlaid with mother-of-pearl, tortoise-shell, and ivory. Silver frets. In front, a figure of Apollo under a canopy and other embellishments in mother-of-pearl. An ornamented sound-hole, the rose being covered with glass. A figure, made of mother-of-pearl, inlaid near the bridge, contains the engraved initials "A. G.," which may be those of the maker of this elegant instrument--possibly Andreas Guarnerius. This mandolino, the handsomest I ever saw, is of the kind called by some musicians "mandurina." It has twelve wire-strings which are arranged in pairs, and therefore produce six tones; while the more common Neapolitan mandolino has eight strings constituting four pairs. A French mandoline, made by Eulry-Clement, in Mirecourt, Vosges, beginning of the present century; the back inlaid with strips of different woods. Eight strings arranged in four pairs. A mandola; Italian, seventeenth century. This scarce instrument may be most briefly described as a huge Neapolitan mandolino. It has the shape of the mandolino, but the size of a large lute; sixteen wire-strings, placed in pairs, produce eight tones of the open strings. The sound is remarkably full and fine. A mandola, similar to the preceding one, inscribed "Gio. Battista, Neapoli, A. D. 1701." Length, 2 ft. 11 in.; depth of body, 10 in. The mandola was played with a quill like the mandolino and the cither. Pandura, two specimens, made in Italy about the year 1700. Bandurria; Spanish, eighteenth century; played with a plectrum usually made of tortoise-shell. Pandore; English, seventeenth century; played with a quill. It is also called chiterna. Pandurina; Italian, about 1700; its nine catgut and wire strings are arranged in pairs tuned in unison, except the lowest, which is single. The open strings, therefore, produce five tones. The neck is provided with catgut frets.
