4 CONNECTION OF SOUND WITII MOTION. [I. § 2. 
explosion of a powder-magazine is capable of shatter¬ 
ing the windows of houses at several miles’ distance. 
Sounds of moderate loudness, such as the rattle of 
carriage-wheels, the stamping of feet, the clapping of 
hands, are produced by movements of solid bodies 
which cannot take place without setting up a very 
perceptible agitation of the air. In the case of 
weaker sounds, the accompanying air-motion cannot, 
it is true, be ordinarily thus recognized ; but, even 
here, a little attention will usually detect a certain 
amount of movement on the part of the sound- 
producing apparatus, which is probably capable of 
being communicated to the surrounding air. Thus, a 
sounding pianoforte-string can be both seen and felt 
to be in motion : the movements of a finger-glass, 
stroked on the rim by a wet finger, can be recognized 
by observing the thrills which play on the surface of 
the water it contains : sand strewed on a horizontal 
drum head is thrown off when the drum is beaten. 
These considerations raise a presumption that Sound 
is invariably associated with agitation of the convey¬ 
ing medium—that it is impossible to produce a 
sound without at the same time setting the medium 
in motion. If this should prove to be the case, there 
would be ground for the further conjecture that mo¬ 
tion of a material medium constitutes the mechanical 
impulse which, falling on the ear, excites within it
