It has been before remarked that Gasparo da Salo did not arrive at his conclusions without mature consideration. In fact, a long and deliberate process of experiment may be traced in his instruments. We find that at times his Violins and Violas were treated differently from the Accordos and Violonos. The Violins are found to be high in model, while the above-named instruments, evidently of the same date, are flat. He would seem to have been desirous of testing the powers of either model, and it is possible that he fostered the idea of varying the construction of each of the four species in the family of stringed instruments according to the part which should be allotted to it. To treat each part of the stringed quartette in a different way is certainly an error, for they are to be looked upon as gradations of one and the same instrument; nevertheless, the attempt of Gasparo, although mistaken, offers but another instance of his prolific ingenuity and unwearied diligence. An praise is due to the great Brescian maker for having opened up, as a pioneer, so wide a field of research. The Cremonese artists followed up his clue, and brought the Violin to the highest state of excellence. [Illustration: _Plate X_. DOMENICO MONTAGNANA. (GEO. GUDGEON, ESQ.)] The chief characteristics of the works of Gasparo da Salo are the sound-holes, shortened centre-bouts, scroll, and peculiar choice of material. The length of the sound-hole at first strikes one as somewhat crude, but as the eye becomes more acquainted with the general form of the instrument, it is seen to be in perfect harmony with the primitive outline. With this sound-hole commences the pointed form to which Giuseppe Guarneri, nearly a century and a half later, gave such perfection. The material used for the larger instruments is mostly pear-wood, or wood of that description, the quality of which is particularly fine. In the selection of this wood he showed a still minuter discrimination, using it generally for Accordos and Violonos, and not for Violins or Violas; few specimens of the latter have backs of pear-wood. His work was bold, but not highly finished; no other result could be looked for at so early a date. The grain of the bellies is usually very even and well defined. Signor Dragonetti, the late eminent Double-Bass player, possessed three or four Double-Basses by this maker of various sizes. The most celebrated of these instruments was presented to him by the monks of the monastery of St. Mark's, Venice, about the year 1776, and was returned to the Canons of that Church (the monks and the monastery having been suppressed since the French occupation of Venice in 1805 or 1809) after Dragonetti's death, in 1846. Another was bequeathed by Dragonetti to the late Duke of Leinster. A third is in the possession of the Rev. George Leigh Blake. Among his chamber Double-Basses the one formerly belonging to Mr. Bennett is regarded as a singularly perfect example. It was
