Présentation de l'éditeur

Mathematical Elements Book IV. We have often fpoken of the A ir already, and as we live in, and are always encompaffed by it, we muft haveR egard to its EfF efts in feveral Experiments, as we have faid; but now we fhall confider its Properties fingly. 2076. We call that Fluid, which covers theS urface of theE arth, and furrounds theE arth on every Side, the A ir. 2077. But it is manifeft that theE arth is furrounded by a Fluid; for we obferv dthat it is cover dby aB ody, that gravitates, whofe Parts yield to any I mpreffion, and are eafily mov damong themfelves, which prefles according to its Height, and whofe Preffure is equal every Way. 2078. Many call any elaflic Fluid whatever A ir ;others affirm that in the A ir, which covers theE arth, there are many Things mixt, which dont belong to the A ir; and that therefore we muft attribute no Properties to it, except thofe, which belong to it, when all thefe Things fhou dbe feparated from it. 2079. But we have clearly explain dwhat we underftand by A ir ;2076. namely this mixt Fluid, by which theE arth is furrounded. And we look upon thofe Parts only as not belonging to it, which are thicker, and cant be rank damong the Parts of the Fluid, but float in it. Definition j. 2080. All the A ir which theE arth is encompajs dwith, confider dtogether, is call dthe A trnojphere of theE arthy orfimply the A tmofphere. Definition 2. 2081. I heH eight of the A ir above theS urface of theE arthy is caW dthe Height of the A trnojphere. 2082. That there is aB ody every where on theS urface of theE arth,, though its Parts generally efcape theS ight, is difcover dby Expe 24. riment .2083. That it yields to any hfiprejjion, and has its Parts eafily mov d, is not doubted by any one. 2084. That it is heavy, is prov dby its prefT ing upon theS urface of other Fluids, and fuftaining them inT ubes. EXPERIMENT I, 2085. Take aG lafs Tub
