 1 I  |                    Lecture I: The Force Of Gravitation~Delivered
 2 I  |         mean by the word power or force? Suppose I take this sheet
 3 I  |         am speaking of a power or force, I am speaking of that which
 4 I  |           which we call power, or force; and you will now be able
 5 I  |        could not happen without a force in the water to produce
 6 I  |      produce the result; but that force is entirely distinct from
 7 I  |       where the whole gravitating force of my body is centred, and
 8 I  |         fall to the earth by this force which we call gravity. By
 9 I  |           head with any degree of force, and it would remain undisturbed.
10 I  |  circumstances connected with the force of Gravitation, especially
11 I  |        some degree considered the force of gravitation - that force
12 I  |       force of gravitation - that force which causes all bodies
13 II |          the board under the word Force - Gravitation - and go a
14 II |       fall to the earth - for the force of gravitation never fails.
15 II |          it I have destroyed that force of which I have placed the
16 II |        properties as respects the force of cohesion.~ ~Here is a

18 II |     particles are arranged by the force of cohesion.~Now we will
19 II |       this calcareous spar by the force of cohesion.~And now I will
20 II |        strain; in these parts the force of cohesion is being exerted
21 II |         all because we weaken the force of cohesion between particle
22 III|  attraction alter a little in its force; either of increasing, or
23 III|           places in opposition to force applied to it. But what
24 III|         Well, in diminishing this force of attraction between the
25 III|            we made use of another force, namely, that of heat; and
26 III|           to understand that this force of heat is always concerned
27 III|           body loses some of that force of attraction by means of
28 III|   contracting so powerfully as to force enough air through the tube
29 III|          lessening the attractive force between its particles, and
30 III|           good deal of attractive force remaining behind. I want
31 III|        sometimes produced by this force of water. I want you now
32 III|        the most important is that force which we call voltaic electricity,
33 III|        means of these wires. This force is produced by the battery
34 III|          is made to submit to the force which I have in these wires;
35 III|         chemical affinity, or the force of chemical action between
36 III|        were when dealing with the force of cohesion; we are dealing
37 III|      matter; I am not speaking of force), which adds no matter to
38 III|           serve to illustrate the force, if I may so call it, of
39 IV |      solid, there is also another force, different from the former -
40 IV |         acts with respect to this force of chemical affinity. If
41 IV |       destroy the exact amount of force exerted by this oxygen.
42 IV |         so with gravitation; this force is continuous, and is just
43 V  |          met with before, but the force is the same. We have here,
44 V  | attraction - a dual attraction or force one attracting and the other
45 V  |            what is the attractive force? it is nothing; but if I
46 V  |         idea of the nature of the force which we call Electricity.
47 V  |          two places in which this force of attraction resides? If
48 V  |         the suspended magnet; the force, then, is no longer attraction,
49 V  |          really concerned in this force, just as in falling the
50 V  |          really acted upon by the force of gravitation. I have here
51 V  |         as belonging to any other force. Let us see whether we have
52 V  |           for the manner in which force may be conducted or transmitted
53 V  |       would not serve to keep the force from you when touching it
54 VI |          the action of some other force. Thus you have seen the
55 VI |            Thus you have seen the force of electricity acting in
56 VI |        its action on the chemical force; and in this case, therefore,
57 VI |         affects another - how the force of heat affects chemical

59 VI |      strange transfer of chemical force from one metal to another;
60 VI |          to another; the chemical force from the zinc is transferred
61 VI |       have the identical chemical force of the particles of zinc
62 VI |       power to make that chemical force, or something it produces,
63 VI |           we do make the chemical force travel from the zinc to
64 VI |       plates all exercising their force at once in sending the whole
65 VI |      thing it is to see that this force is brought away from the
66 VI |           flash, so strong is the force. You thus see, from the
67 VI |          see, from the attractive force at the two ends of this
68 VI |        nor less than the chemical force of the zinc - its very force
69 VI |      force of the zinc - its very force carried along wires and
70 VI |           power over the chemical force, how wonderfully we are
71 VI |           power of conveying this force from place to place. I have
72 VI |         See what an exhibition of force we have! We have exhausted
73 VI |          which we can convey this force, where under ordinary circumstances,
74 VI |  resistance to the passage of the force, you see what an amount
