with their octaves, each tone having two strings tuned in an octave. The archlute, or bass-theorbo, is the largest sized kind of the theorbo, or lute with a double neck. An Italian archlute, inscribed: "Matheus Bucchenberg, Roma, 1619." From Signor Mario's museum. Bucchenberg, or Bueckenberg as he was more generally called, was one of the most celebrated lute-makers in Italy, and a German by birth. The present archlute has three ornamented sound-holes. It is provided with a mechanism by means of which any one of the bass strings by the side of the finger-board can be raised a semitone in pitch at the pleasure of the performer. This ingenious contrivance, which renders the bass strings more useful in compositions having modulations into distant major or minor keys, occurs also on a French theorbo dating from about the year 1700, which is in my collection. But on this French theorbo, the mechanism acts upon all the strings beside the finger-board simultaneously, while on the archlute just noticed it is contrived so that any single string may be altered in pitch independently of others. As the mechanism is evidently not a later addition, but was made with the instrument in 1619, it is suggestive to musical antiquarians, inasmuch as it reveals a higher degree of progress in the construction of the lute than is generally supposed to have been attained about the beginning of the seventeenth century. An Italian theorbino, or the smallest kind of theorbo, seventeenth century; with sixteen strings, six of which run beside the finger-board. A chitarrone, or large Roman theorbo; Italian. Inscription: "Vitus de Angelis, Bonon, 1609." It is about six feet long, and has twenty-one strings. The chitarrone was formerly called Roman theorbo, because it was principally used at Rome. There was a similar instrument popular at Padua, somewhat smaller in size. The present specimen was made in Bologna. The chitarrone was used in the orchestra, assisting at dramatic performances as well as in church music. It was often strung with wire instead of catgut; the same was the case with the common theorbo of Germany and England. A chitarrone, with marquetry and three ornamented sound-holes; made by M. Bueckenberg, in Rome, anno 1614. From Signor Mario's collection. An Irish harp (clarseth), strung with wire; made by Egan, in Dublin, in the beginning of the present century. An arpanetta (German, Spitzharfe), English, seventeenth century; with one hundred steel wire-strings and thirty-five brass wire-strings. A b˚che (German, Scheidholt), from Val d'Ajol, in the Vosges mountains, in France; made in the beginning of the present century. An English specimen of the _hummel_, probably made during the eighteenth century; with twelve wire strings. It resembles the b˚che, and may be regarded as an antiquated species of our present horizontal cither. A bell-harp, made by John Simcock, in Bath, about the year 1700: length, 20 in. It has sixteen tones. Each tone is produced by
