and feen the Invention there defcribed, and made ufe 
of in Italy at Tivoli , and feveral other Places, called 
Soffi d\ Acqua , and doth with Attention confider the 
following Defcription, will, I hope, be convinced, 
that this new Invention of Water-Bellows is built on 
the very felf-fame Foundation, to which Leathern and 
Wooden Bellows owe their Ufe and Being, and will 
in feveral Cafes prove of more fignal Service. 
Thefe Water-Bellows A and A, reprefented in the 
Figure annexed, are made of Wood, not unlike the 
Shape of Diving-Bells, in the Form of a Conus Trun- 
catus y and confequently wider below than at top, 
where they are furnifhed with clofe Heads B and B, 
but at the lower Ends E andE, quite open. At the 
Heads B and B, are two Valves V and V, which open 
inwardly, and are made like the Claps of other Bel- 
lows y with their Hinges, and the Valves themfelves 
covered with Hatters Felt, and are (hut by an eafy Steel 
Spring, till the Air from above opens the fame, which =- 
happens only when thefe Bellows receive their Mo- 
tion upwards j but are fhut by means of the Preffure 
of the Air within, when they fink down into the 
Water. On the very fame Heads are two pliable Lea- 
thern Tubes R and R, fixed one at the Top of each 
Water -Bellows , which Tubes are made and prepared 
in the fame manner as thofe ufed in Water-Engines 
for extinguifhing of Fire, Thefe Leathern Tubes or 
$ipes reach from the Bellows to Wooden Tubes 
T, T, which carry the Wind into the Iron Furnace 
M, or any other Place, according to Pleafure. 
Thefe Bellows are likewife provided with Iron 
Chains k, K, which are fattened to two Sweeps S, S, 
by which means they hang perpendicular from the 
Beam
