visible. The corners are drawn out to points of singular fineness, and this gives them an appearance of prominence which serves to throw beauty into the entire work. The model is raised somewhat towards the centre, dipping rather suddenly from the feet of the bridge towards the outer edge, and forming a slight groove where the purfling is reached, but not the exaggerated scoop which is commonly seen in the instruments of the many copyists. This portion of the design has formed the subject of considerable discussion among the learned in the Violin world, the debatable points being the appearance of this peculiarity and its acoustic effect. As regards the former question, the writer of these pages feels convinced that the apparent irregularity is in perfect harmony with the general outline of the great Amati's instrument; and it pleases the eye. From the acoustical point of view, it may be conceded that it does not tend to increase of power; but, on the other hand, probably, the sweetness of tone so common to the instruments of Niccolo Amati must be set to its credit; for, in proportion as the form is departed from, the sweetness is found to decrease. The sound-hole has all the character of those of the preceding Amati, together with increased boldness; in fact, it is a repetition of that of Girolamo, with this exception. The sides are a shade deeper than those of the brothers Amati. The scroll is exquisitely cut. Its outline is perhaps a trifle contracted, and thus is robbed of the vigour which it would otherwise possess. From this circumstance it differs from the general tenor of the body, which is certainly of broad conception. The maker would seem to have been aware of this defect, if we may judge from the difference of form given to his earlier scrolls, as compared with those of a later date, in which he seems to have attempted to secure increased boldness, as more in keeping with the character of the body of the instrument. It must be acknowledged, however, that these efforts did not carry him far enough. The surface of the scroll is usually inclined to flatness. The wood used by Niccolo Amati for his grand instruments is of splendid quality, both as regards acoustical requirements and beauty of appearance. The grain of some of his backs has a wave-like form of much beauty, others have markings of great regularity, giving to the instrument a highly finished appearance. The bellies are of a soft silken nature, and usually of even grain. A few of them are of singular beauty, their grain being of a mottled character, which, within its transparent coat of varnish, flashes light here and there with singular force. The colour of the varnish varies in point of depth; sometimes it is of a rich amber colour, at others reddish-brown, and in a few instances light golden-red.
