 1   I,  1 |         causes of nature, and all natural motion, also the stars ordered
 2   I,  1 |    concerned with events that are natural, though their order is less
 3   I,  4 | compulsory motion downwards and a natural motion upwards, and under
 4   I,  8 |           upper motion. For it is natural to suppose that, if the
 5   I,  8 |         and the most stars, it is natural to suppose that they are
 6   I,  14|      obviously artificial and not natural. And Egypt was nothing more
 7   I,  14|         That this should be so is natural, since the lower land came
 8  II,  1 |          to one or other of them. Natural standing water from springs
 9  II,  2 |    remains behind, but not in its natural place. For this is a question
10  II,  2 |       discussed (I mean about the natural place that water, like the
11  II,  2 |        the sea filling is not its natural place but that of water.
12  II,  2 |        has been drawn away by the natural animal heat and has passed
13  II,  2 |       have explained. It is quite natural that some people should

15  II,  3 |           explained most of their natural operations and affections.~
16  II,  4 |         and winds appear in their natural proportion according to
17  II,  4 |        evaporation is wind, it is natural that the most and most important
18  II,  9 |         that everything hot has a natural tendency upwards. Just as
19  IV,  1 |           true becoming, that is, natural change, is always the work
20  IV,  1 |           so is the corresponding natural destruction; and this becoming
21  IV,  1 |     animals and their parts. True natural becoming is a change introduced
22  IV,  1 |     becoming is putrefaction. All natural destruction is on the way
23  IV,  1 |      these things, that is of all natural objects, except such as
24  IV,  1 |         or anything else, but the natural course of their destruction
25  IV,  1 |   destruction of the peculiar and natural heat in any moist subject
26  IV,  1 |       heat departs and causes the natural moisture to evaporate with

28  IV,  2 |           up in actually existing natural objects as matter.~Of these
29  IV,  2 |         is a process in which the natural and proper heat of an object

33  IV,  3 |         state is due to a lack of natural heat and its disproportion
34  IV,  3 |         in an artificial and in a natural instrument, for the cause
35  IV,  8 |         and all other homogeneous natural bodies. Let us begin by
