 1 I |            live and stand upon the earth, we should hardly be aware
 2 I |           geological strata of the earth, in which there is a more
 3 I |       water should fall toward the earth, and therefore the very
 4 I |       water gravitating toward the earth. Now here [exhibiting a
 5 I |        which gravitates toward the earth as much as the whole of
 6 I |           full] to fall toward the earth, compared with the little
 7 I |            power of falling to the earth. Again, here is another
 8 I |           the falling body and the earth. Let us be slow and careful
 9 I |           this. It is not that the earth has any particular attraction
10 I |          other. It is not that the earth has any special power which
11 I |          just as much power as the earth has to attract these two
12 I |        they fall so quickly to the earth is owing to its greater
13 I |        bodies are attracted to the earth, or, to use a more learned
14 I |           that it falls toward the earth, and, if not intercepted,
15 I |           centre of gravity of the earth, which I will explain to
16 I |            and all fall toward the earth, and what I want you to
17 I |        liquids tend to fall to the earth; and, therefore, you will
18 I |           things, attracted to the earth.~There is another point
19 I |           get to the centre of the earth; that is to say, the whole
20 I |            attracting power of the earth is, as it were, centred
21 I |            and raising it from the earth. All this is effected by
22 I |        heavy or light, fall to the earth by this force which we call
23 I |            they reach the table or earth at different times; that
24 I |           fall equally fast to the earth. There are one or two beautiful
25 I |     perceive they both fall to the earth in the same time. Now if
26 I |        together falling toward the earth, fall with the same velocity,
27 I |        should they not fall to the earth with the same quickness?
28 II|          it became as large as the Earth itself - or I might take
29 II|       itself - or I might take the Earth itself as the large ball -
30 II|       balanced with respect to the earth; and I need not tell you
31 II|   gravitation to the centre of the earth.~I must not, however, leave
32 II|   gravitate - they all fall to the earth - for the force of gravitation
33 II|           up the structures on the earth are of strength - we use
34 V |          ages in the bowels of the earth. Now we can make artificial
35 V | electricity from going away to the earth. If, therefore, I were to
36 VI|      together in the bowels of the earth, perhaps ages and ages ago,
