Analyfis of the Air 9 2 op 
Experiment LXXXVIIL 
I filled the ftrong Hungary -water Bottle 
h c (Fig. 3 6.) near half full of Feafe, and then 
full of water, pouring in firft half an inch 
depth of Mercury j then I fere wed at b in» 
to the bottle the long (lender tube a 
which reached down to the bottom of the 
bottle ; the water was in two ot three days 
all imbibed by the Peafe, and they thereby 
much dilated 5 the Mercury was alfo forced 
up the (lender glafs tube near 80 inches high 5 
in which'ftate the new generated air in the 
bottle was compreffed with a force equal 
to more than two atmofpheres and an half; 
if the bottle and tube were fwung to and 
fro, the Mercury would make long vibra- 
tions in the tube between z, and b> which 
proves the great elafticity of the compreffed 
air in the bottle. 
Experiment LXXXIX. 
I found the like elaftick force by the fol- 
lowing Experiment, viz. I provided a ftrong 
iron pot abed (Fig. 37.) which was 2 andf 
inches diameter within fide, and five inches 
deep. I poured into it half an inch depth 
of Mercury; then 1 put a little coloured
