For if a certain quantity of matter, as thecompressed air in a condensing engine, exertsa force to dilate itself every way (speakingafter the common manner, as if it were ac-tive) and take up more room, the parts ofit have a tendency to recede from each other.No fort of attraction can explain such anappearance. Nor will little elastic convolutes,rolled up like the spring of a watch, norsmall globules replenished with yet a moresubtil elastic matter, agree with the perfectfluidity observed as much in all degrees ofthe compression of the air, as in its dilata-tion (f) : not to mention that these hypo-theses
