with his head ſo ſar under Water, as he may put his head into the Pail, and
there will come as much Air bubbling forth, as will make room for his
head. Then let him ſpeak, and any that ſhall ſtand without, ſhall hear his
voice plainly, but yet made extream ſharp and exile, like the voice of
Puppets: But yet the Articulate Sounds of the words will not be confound-
ed. Note, that it may be much more handſomly done, if the Pail be put
over the Mans head above Water, and then he cowre down, and the
Pail be preſſed down with him. Note, that a man muſt kneel or ſit, that
he may be lower than the Water. A man would think, that the Sici-
lian Poet had knowledge of this Experiment; for he ſaith, that Hercules’s
Page Hylas went with a Water-pot, to fill it at a pleaſant Fountain that was
near the ſhore, and that the Nymphs of the Fountain fell in love with the
Boy, and pulled him under the Water, keeping him alive; and that Her-
cules miſſing his Page, called him by his name aloud, that all the ſhore rang
of it; and that Hylas from within the Water anſwered his Maſter; but (that
which is to the preſent purpoſe) with ſo ſmall and exile a voice, as Hercules
thought he had been three miles off, when the Fountain (indeed) was
faſt by.

In Lutes and Inſtruments of Strings, if you ſtop a ſtring high, where-
11156. by it hath leſs ſcope to tremble, the Sound is more Trebble, but yet more
dead.

Take two Sawcers, and ſtrike the edge of the one againſt the bottom
22157. of the other, within a Pail of Water, and you ſhall finde that as you put
the Sawcers lower and lower, the Sound groweth more flat, even while
part of the Sawcer is above the Water; but that flatneſs of Sound is joyned
with a harſhneſs of Sound, which, no doubt, is cauſed by the inequality of
the Sound, which cometh from the part of the Sawcer under the Water, and
from the part above. But when the Sawcer is wholly under the Water, the
ſound becometh more clear, but far more low, and as if the ſound came
from a far off.

A ſoft body dampeth the ſound, much more than a hard;
and if a Bell
33158. hath cloth or ſilk wrapped about it, it deadeth the ſound more than if it were
Wood. And therefore in Clericals, the Keyes are lined, and in Colledges they
uſe to line the Table-men.

Tryal was made in a Recorder after theſe ſeveral manners.
The bottom
44159. of it was ſet againſt the Palm of the Hand, ſtopped with Wax round about,
ſet againſt a Damask Cuſhion, thruſt into Sand, into Aſhes, into Water,
(half an inch under the Water) cloſe to the bottom of a Silver Baſin,
and ſtill the Tone remained: But the bottom of it was ſet againſt
a Woollen Carpet, a Lining of Pluſh, a Lock of Wool, (though looſly
put in;) againſt Snow, and the ſound of it was quite deaded, and but
breath.

Iron hot produceth not ſo full a ſound, as when it is cold;
for while it is
55160. hot, it appeareth to be more ſoft, and leſs reſounding. So likewiſe warm Wa-
ter, when it faileth maketh not ſo full a ſound as cold; and I conceive it is
ſofter, and nearer the nature of Oyl; for it is more ſlippery, as may be per-
ceived, in that it ſco wreth better.

Let there be a Recorder made with two Fipples at each end one;
the
66161. Trunck of it of the length of two Recorders, and the holes anſwerable to-
wards each end, and let two play the ſame Leſſon upon it, at an Uniſon;
and let it be noted, whether the ſound be confounded, or amplified, or
dulled. So likewiſe let a Croſs be made of two Truncks
