8652Natural Hiſtory;
It is worthy the inquiry, whether great Sounds (as of Ordnance or
11216. Bells) become not more Weak and Exile, when they paſs thorow ſmall
Cranies. For the Subtilties of Articulate Sounds, (it may be) may paſs
thorow ſmall Cranies, not conſuſed; but the magnitude of the Sound (per-
haps) not ſo well.

THe Mediums of Sounds, are Air, ſoft and porous Bodies;
alſo Water,
22217. and hard Bodies reſuſe not altogether to be Mediums of Sounds. But all

In Air, the thinner or drier Air, carrieth not the Sound ſo well, as the
44218 more denſe; as appeareth in Night Sounds, and Evening Sounds, and
Sounds in moiſt Weather, and Southern Winds. The reaſon is already
mentioned in the Title of Majoration of Sounds; being, for that thin Air is
better pierced, but thick Air preſerveth the Sound better from waſte: Let
further Tryal be made by hollowing in Miſts, and gentle Showers; for (it
may be) that will ſome what dead the Sound.

How far forth Flame may be a Medium of Sounds, (eſpecially of ſuch
55219. Sounds as are created by Air, and not bet wixt hard Bodies) lebit be tried
in ſpeaking, where a Bonefire is between; but then you muſt allow for ſome
diſturbance, the noiſe that the Flame it ſelf maketh.

Whether any other Liquors being made Mediums, cauſe a diverſity of
66220. Sound from Water, it may be tryed: As by the knapping of the Tongs, or
ſtriking the bottom of a Veſſel filled either with Milk or with Oyl;
which though they be more light, yet are they more une qual Bodies than
Air.

Of the Natures of the Mediums, we have now ſpoken;
as for the Diſpoſi-
# tion of the ſaid Mediums, it doth confiſt in the Penning, or not Penning
# of the Air; of which, we have ſpoken before in the Title of Delation of
# Sounds. It conſiſteth alſo in the Figure of the Concave, through which
# it paſſeth. Of which, we will ſpeak next.

which the Concaves receive; or in reſpect of the carrying of Sounds longer
or ſhorter way; or in reſpect of many other Circumſtances, they have been
touched, as falling into other Titles. But thoſe Figures which we now are
to fpeak of, we intend to be, as they concern the Lines, through which
Sound paſſeth: As Straight, Crooked, Angular, Circular, & c.

The Figure of a Bell partaketh of the Pyramis, but yet coming off, and
88221. dilating more ſuddenly. The Figure of a Hunters Horn, and Cornet, is oblick, yet
they have likewiſe ſtraight Horns; which if they be of the ſame bore with
the oblick, differ little in Sound, ſave that the ſtraight require ſome what a
ſtronger blaſt. The Figure of Recorders, and Flutes, and Pipes, are ſtraight;
but the Recorder hath a leſs bore, and a greater, above and below. The Trumpet
hath the Figure of the Letter S. which maketh that Purling Sound, & c. Gene-
rally, the ſtraight Line hath the cleaneſt and roundeſt Sound, and the crooked
the more Hoarſe, and Jarring.
