yet generally music feedeth that disposition of 112. Tones are not so apt altogether to procure the spirits, which it findeth. We see also, that sleep as some other sounds; as the wind, the several airs and tunes do please several nations purling of water, humming of bees, a sweet voice and persons, according to the sympathy they have of one that readeth, &c. The cause whereof is, with their spirits. for that tones, because they are equal and slide not, do more strike and erect the sense than the Experiments in consort touching sounds; and first other. And overmuch attention hindereth sleep. touching the nullity and entity of sounds.

Again, the falling from a discord advise; which is, after long inquiry of things to a concord, which maketh great sweetness in immersed in matter, to interpose some subject music, hath an agreement with the affections, which is immateriate, or less materiate; such as which are reintegrated to the better, after some this of sounds; to the end, that the intellect may dislikes; it agreeth also with the taste, which is be rectified, and become not partial. soon glutted with that which is sweet alone. 115.

The cause is, for that the winds, in a plain, except they be strong, make no sense of hearing striketh the spirits more immedi- noise; but amongst trees, the noise of such ately than the other senses; and more incorpore- winds will be perceived. And the winds, generally than the smelling; for the sight, taste, and ally, when they make a noise, do ever make it feeling, have their organs not of so present and unequally, rising and falling, and sometimes, immediate access to the spirits as the hearing when they are vehement, trembling at the height hath.

Water in a river, though a swift object odorate; but harmony entering easily, and stream, is not heard in the channel, but runneth mingling not at all, and coming with a manisest in silence, if it be of any depth; but the very motion, doth by custom of often affecting the stream upon shallows, of gravel or pebble, will spirits, and putting them into one kind of posture, be heard. And waters, when they beat upon the alter not a little the nature of the spirits, even shore, or are straitened, as in the falls of bridges, when the object is removed. And therefore we or are dashed against themselves, by winds, give see, that tunes and airs, even in their own nature, a roaring noise.

So as it is no marvel though the upper body press the lower body if they alter the spirits, considering that tunes down, make no noise. So the motion in the have a predisposition to the motion of the spirits minute parts of any solid body, which is the

But it seemeth to me impossible; string be not strained, it maketh no noise. But for if the air pent be driven forth, and strike the where the air is pent and straitened, there breath air open, it will certainly make a noise. As for or other blowing, which carry but a gentle per- the white powder, if any such thing be, that may cussion, suffice to create sound; as in pipes and extinguish or dead the noise, it is like to be a wind-instruments. But then you must note, that mixture of petre and sulphur, without coal. For in recorders, which go with a gentle breath, the petre alone will not take fire. And if any man concave of the pipe, were it not for the fipple that think that the sound may be extinguished or straiteneth the air, much more than the simple deaded by discharging the pent air, before it concave, would yield no sound. For as for other cometh to the mouth of the piece and to the open wind-instruments, they require a forcible breath; air, that is not probable; for it will make more as trumpets, cornets, hunters' horns, &c., which divided sounds: as if you should make a crossappeareth by the blown cheeks of him that barrel hollow through the barrel of a piece, it windeth them.
