1explanation of the reinforcement of the strings produced by the body of the instrument is false. The two tables vibrate in the whole of their length, which can be proved by sprinklings and over their surfaces, and a body which has been broken and reglued, vibrates before and after its rupture in precisely the same manner; it produces still the same nodal figures with the sand, as one can prove with discs of wood, metal, or rock-crystal, &c. It is also a natural result of the laws of the propagation of vibratory movements. A violin presents upon both its upper and lower surfaces, nodes and ventral segments where we see the sand strongly agitated. The tables then are composed as plates, and not of fibres vibrating separately.
3A violin is composed of a great number of elements, each having its proper function, and which we shall now enumerate successively.
5Let us first examine the part played by the sound-post. If we take away this piece the sound loses its intensity and quality, and becomes poor. It regains its strength and purity as soon as we restore this important element. We cannot suppose that the sound-post acts as a conductor of the sound, or serves only to propagate the movement, for we can place this piece, not in the violin itself but upon it, and its action remains the same, its influence is not changed.
7We place upon the violin a kind of arch of wood, glued upon the corner blocks, and we place the sound-post between this arch and the belly of the instrument; the effect produced is the same as in ordinary circumstances, when the post is in its place inside the
