 1 I  |           does it abundantly with water, which, being raised to
 2 I  |         from them. The gravity of water we use as moving force,
 3 I  |        act as receptacles for the water, and, on the side turned
 4 I  |      buckets are upside-down. The water flows at M into the buckets
 5 I  |        former are weighted by the water contained in them, the latter
 6 I  |     latter not; the weight of the water acts continuously on only
 7 I  |    resistance, for it contains no water. It is thus the weight of
 8 I  |         the weight of the falling water which turns the wheel, and
 9 I  |         once see that the mass of water which turns the wheel must
10 I  |          sources of moving force.~Water power was the first inorganic
11 I  |       near his palace there was a water wheel. Its use was first
12 I  |        Emperors. Even now we find water mills in all mountains,
13 I  |       brooks and streams. We find water power used for all purposes
14 I  |          to produce any amount of water power.~Before passing to
15 I  |           wheel, described above, water acts by its weight. But
16 I  |         the height from which the water comes is not great enough
17 I  |        wheels dips in the flowing water which strikes against their
18 I  | neighborhood of such a wheel, the water need not necessarily have
19 I  |         It is the velocity of the water, exerting an impact against
20 I  |        supply the want of falling water, afford another instance
21 I  |        little drive a windmill as water at rest a water wheel. The
22 I  |       windmill as water at rest a water wheel. The driving force
23 II |         power. In the case of the water mill, or of the windmill,
24 II |           of the moving masses of water and air is necessary to
25 II |         expansion, is replaced by water, which is gradually changed
26 II |         and the small quantity of water which are the sources of
27 II |        middle of the ocean; while water and windmills are bound
28 II |        large towns where wind and water power are wanting, can be
29 II |      latent. On this view, liquid water differed from solid ice
30 II |      precipitated, and the liquid water restored to the state of
31 II |           the vaporisation of the water.~Finally, heat is sometimes
32 II |       heat which the newly formed water must have here assimilated
33 III|  necessary to raise one gramme of water through one degree centigrade.
34 III|           of experiments in which water was heated by friction in
35 III|        vessel was substituted for water in a brass one, gave 425
36 III|           to raise 80.9 pounds of water from the freezing to the
37 III|          product of combustion is water, which, therefore, is not
38 III|          the form of heat. In the water which has been formed during
39 III|    vessels filled with acidulated water a and a1, which are separated
40 III|       porous plate moistened with water. In both sides are fitted
41 III|           transmitted through the water by the platinum wires, k,
42 III|           are the two elements of water, hydrogen on the one hand,
43 III|           glass flask filled with water over the hydrogen flame,
44 III|           the hydrogen flame, the water, newly formed in combustion,
45 III|           been liberated from the water by the electrical current
46 III|          current which decomposes water. This current is itself
47 III|          for the decomposition of water.~If now the conducting circuit
48 III|          and the decomposition of water begins, a chemical process
49 III|       oxygen from the surrounding water and undergoes a slow combustion.
50 III|           from it is taken by the water from the nitric acid surrounding
51 III|        one product of combustion, water, is again separated, a new
52 III|           with oxygen and acid to water in the decomposing cell,
53 III|         apparatus for decomposing water, we obtain hydrogen and
54 III|        forces. We have decomposed water into its elements by such
55 IV |    universe. The force of falling water can only flow down from
