to the bottle the long (lender tube a z , 
which reached down to the bottom of the 
bottle 3 the water was in two or three days all 
imbibed by thePcafe, and they thereby much I 
dilated; the Mercury wasalfo forced up the ! 
flender glafs tube near 8p inches high; in 1 
which flate the new generated Air in the 3 
bottle was comprefled with a force equal 
to more than two Atmofpheres and an half 3 
if the bottle and tube were fwung too and 
fro, the xMcrcury would make long vibra^ 
tions in the tube between z and which 
proves the great elafticity of the comprefTed | 
■^h in the bottle.
