82 NATURAL HISTORY. 



carried with wind : and therefore sounds will be 

 heard further with the wind, than against the wind ; 

 and likewise do rise and fall with the intension or 

 remission of the wind. But for the impression of 

 the sound, it is quite another thing, and is utterly 

 without any local motion of the air, perceptible ; and 

 in that resembleth the species visible : for after a 

 man hath lured, or a bell is rung, we cannot discern 

 any perceptible motion at all in the air along as the 

 sound goeth ; but only at the first. Neither doth 

 the wind, as far as it carrieth a voice, with the 

 motion thereof, confound any of the delicate and ar 

 ticulate figurations of the air, in variety of words. 

 And if a man speak a good loudness against the flame 

 of a candle, it will not make it tremble much ; though 

 most when those letters are pronounced which 

 contract the mouth ; as F. S. V. and some others. 

 But gentle breathing, or blowing without speaking, 

 will move the candle far more. And it is the more pro 

 bable, that sound is without any local motion of the 

 air, because as it differeth from the sight, in that it 

 needeth a local motion of the air at first ; so it paral- 

 leleth in so many other things with the sight, and 

 radiation of things visible ; which without all ques 

 tion, induce no local motion in the air, as hath been 

 said,

 of thunder, and great ordnance, glass windows will 

 shake ; and fishes are thought to be frayed with the 

 motion caused by noise upon the water. But these 

 effects are from the local motion of the air, which is
