AnaJyJis of the Air. 1 1 j 



v - ing the particles of air to be fpringy and 

 ki ramous, or rolled up like hoops, or by any 

 " other means than by a repulfive power." 

 The truth of which is further confirmed by 

 thefe Experiments, which mew rhe great 

 quantity of air emitted from fermenting bo- 

 dies ; which not only proves the great force 

 with which the parts of thofe bodies muft 

 be diftended ; but (hews alio how very much 

 the particles of air muft be coiled up in that 

 ftate, if they are, as has been fuppofed, fpringy 

 and ramous. 



To inftance in the cafe of the pounded 

 Apples, which generated above 48 times 

 their bulk of air ; this air, when in the 

 Apples, muft be comprefled into lefs than 

 a forty-eighth part of the fpace it takes up 

 when freed from them, and it will confe- 

 quently be forty-eight times more denfe - y 

 and fince the force of comprefled air is pro- 

 portional to its denfity, that force which 

 comprefles and confines this air in the Ap- 

 ples, muft be equal to the weight of forty- 

 eight of our atmofpheres, when the Mer- 

 cury in the Barometer ftands at fair, that is, 

 30 inches high.
