16  II,  13|         underlies it; while the air, not having room enough

18  II,  13|          For the reason why the air is so closely confined that
19  II,  13|  observations of liquids and of air, in which the larger and

21  II,  13|        are alike to it, and the air above the earth does not
22  II,  13|    movement, then no more could air below it prevent downward
23 III,  2 |       alone. In either case the air is as it were instrumental
24 III,  2 |  instrumental to the force. For air is both light and heavy,
25 III,  2 |       it were, impregnating the air. That is why a body moved
26 III,  2 |          Otherwise, i.e. if the air were not endowed with this
27 III,  2 |       generated out of another, air for instance out of fire,
28 III,  4 |       allot the sphere to fire. Air, water, and the rest they

33 III,  5 |        which is either water or air or a body finer than water
34 III,  5 |      than water and denser than air, and proceed to generate
35 III,  5 |        between fire, water, and air, but one and the same body
36 III,  5 |    relatively to something else air. The same difficulty is
37 III,  5 |    ratio to one another must be air, fire, earth, and water
38 III,  5 |    related to the total mass of air as the elements of each
39 III,  5 |        on, and if there is more air than water and, generally,
40 III,  5 |         be smaller than that of air. But the lesser quantity
41 III,  5 |      the greater. Therefore the air element is divisible. And
42 III,  5 |     fire and relatively to that air, to others again water and
43 III,  7 |      water is a body present in air and excreted from air, since
44 III,  7 |        in air and excreted from air, since air becomes heavier
45 III,  7 |        excreted from air, since air becomes heavier when it
46 III,  7 |       but when water turns into air, the room occupied is increased.
47 III,  7 |        converted into vapour or air the vessel which contains
48 III,  8 |          particularly water and air. In such a case the shape
49  IV,  2 |    heavier is to have more, and air, water, and fire are composed
50  IV,  2 |         be a certain quantum of air which is heavier than water.
51  IV,  2 |      The larger the quantity of air the more readily it moves
52  IV,  2 |      upward, and any portion of air without exception will rise
53  IV,  2 |   generation than ours, have an air of novelty. It is apparent
54  IV,  2 |        it will follow that much air or fire is heavier than
55  IV,  3 |          water, I mean, is like air and air like fire, and between
56  IV,  3 |         I mean, is like air and air like fire, and between intermediates
57  IV,  3 |     them and the extremes; thus air is like water, but water
58  IV,  3 |     will be first. Now whenever air comes into being out of
59  IV,  4 |      bottom of others. Such are air and water. Neither of them
60  IV,  4 |       absolute lightness, since air in any quantity rises to
61  IV,  4 | quantity sinks to the bottom of air. Now other bodies are severally
62  IV,  4 |     another, and vice versa. In air, for instance, a talent’
63  IV,  4 |      anywhere but in earth, and air is heavy when not in water
64  IV,  4 |        weight except fire, even air. Of this we have evidence
65  IV,  4 |          A body, then, in which air preponderates over earth
66  IV,  4 |      and yet heavier than it in air, since such a body does
67  IV,  4 |         a body does not rise in air but rises to the surface
68  IV,  4 |     fire to move upward even in air itself, while the air remains
69  IV,  4 |        in air itself, while the air remains at rest-clearly
70  IV,  4 |        light; namely, water and air. But in our view the continent
71  IV,  5 |      the downward motion. Hence air and water each have both
72  IV,  5 |      things except earth, while air rises to the surface of
73  IV,  5 |         the body next below it, air to the place of water and
74  IV,  5 |    earth. But if the fire above air is removed, it will not
75  IV,  5 |     when the upward movement of air which has had a common surface
76  IV,  5 |     move upward to the place of air, except in the manner just
77  IV,  5 |     fails to move downward when air is withdrawn from beneath
78  IV,  5 |         quicker than earth: for air in sufficiently large quantity
79  IV,  5 |     manifest that no portion of air whatever moves downward.
80  IV,  5 |   intermediate bodies behave as air and water behave. Suppose,
81  IV,  5 |        downward, plenum; and in air, it will be said, fire preponderates,
82  IV,  5 |         more fire than a little air, and a large amount of air
83  IV,  5 |      air, and a large amount of air will contain more earth
84  IV,  5 |       we shall have to say that air in a certain quantity moves
85  IV,  5 |       because it has plenum, so air goes to its own place above
86  IV,  5 |       water will excel a little air in the upward movement and
87  IV,  5 |         the upward movement and air excel water in the downward
88  IV,  6 |      materials which throng the air. With regard to these questions,
89  IV,  6 |     objection is feeble. In the air, he says, the "drive" (meaning
90  IV,  6 |    which is easily divided; and air is more so than water, water
91  IV,  6 |       with far greater force to air, since it is so much more
