...either heated or inflammable air, if at liberty, will afcerid in the atmofphere with a force of buoyancy equal to the difference between its own weight and the weight of an equal bulk of common air (9, B). If the heated or the inflammable air be included in a bag, and... | |

...the fpecific gravity of B were greater or lefs than that of F, it would evidently defcend, or afcend, with a force equal to the difference between its own weight and that of an equal bulk of the fluid ; for the preflure upon the imaginary plane sr, would clearly be... | |

...becomes considerably lighter than the air which it displaces. It will therefore ascend in the atmosphere with a force equal to the difference between its own weight and that of the air it displaces. This difference, if the balloon be sufficiently large, is so considerable,... | |

By enlarging ing the floating ball, a force may be obtained sufficiently great to move those parts of the machinery... | |
