' I filled the ftrong Hungary-water Bottle 

 be Fig. 36. near half full of Peafe, and then 

 full of water, pouring in firft half an inch 

 depth of Mercury; then I fcrewed at b in- 

 to the bottle the long {lender tube a z 

 which reached down to the bottom of the 

 bottle 1 the water was in two or three days all 

 imbibed by the Peafe, and they thereby much 

 dilated j the Mercury was alfo forced up the 

 flender glafs tube near So inches high} in 

 which ftate the new generated Air in the 

 bottle was comprefled with a force equal 

 to more than two Atmofpheres and an half; 

 *jf the bottle and tube were fwung too and 

 °fro, the Mercury would make Jong vibra- 

 tions in the tube between z and b, which 

 proves the great elafticity of the comprefled 

 air in the bottle.
