  1 I   |          not always left to our own power, and we must submit to circumstances
  2 I   |         thinking that next week our power shall be greater, why then,
  3 I   |            which I mean by the word power or force? Suppose I take
  4 I   |        therefore brought into use a power of doing so - the power
  5 I   |             power of doing so - the power of my hand carried on through
  6 I   |           side, I bring into play a power, but a very different exertion
  7 I   |          very different exertion of power from the former; or, if
  8 I   |         shell-lac, therefore, has a power wherewith it acts upon the
  9 I   |         exercise of another kind of power, I might use gunpowder with
 10 I   |             when I am speaking of a power or force, I am speaking
 11 I   |       present with the name of that power, but it is clear there was
 12 I   |          those things which we call power, or force; and you will
 13 I   |     illustration of another kind of power in that lamp; there is a
 14 I   |            in that lamp; there is a power of heat - a power of doing
 15 I   |        there is a power of heat - a power of doing something, but
 16 I   |         something, but not the same power as that which pulled the
 17 I   |             thoughts to one kind of power. You see what I mean by
 18 I   |         reference to the amounts of power which it contains; but it
 19 I   |            body of water down. That power is what we call gravity,
 20 I   |           it, you will find another power and property in the water. 4
 21 I   |          entirely distinct from its power of falling to the earth.
 22 I(4)|                                     Power or property in water. This
 23 I(4)|             property in water. This power - the heat by which the
 24 I   |          illustrate another kind of power. [The lecturer here poured
 25 I   |              in consequence of this power of heat brought into play
 26 I   |         these various matters - the power of heat evolved by acting
 27 I   |            lime with water, and the power which water has of turning
 28 I   |             simple exertion of this power of matter called weight
 29 I   |             it the exercise of that power of pressing downward is
 30 I   |             of the iron, and of the power which the air possesses
 31 I   |         yourselves what a wonderful power there must be to pull this
 32 I   |        another illustration of this power. You know what a pendulum
 33 I   |     by-and-by how this is. Now that power which caused the water to
 34 I   |           fro of the pendulum, that power is entirely due to the attraction
 35 I   |           the earth has any special power which these balls themselves
 36 I   |          have not; for just as much power as the earth has to attract
 37 I   |          ivory balls], just so much power have they in proportion
 38 I   |             has its own gravitating power, as you perceive when I
 39 I   |         which all their gravitating power is centred, and that point
 40 I   |             whole of the attracting power of the earth is, as it were,
 41 II  |           each other, and that this power we called gravitation. I
 42 II  |        might suppose that the whole power of this attraction was exerted
 43 II  |            and all by means of this power of gravitation to the centre
 44 II  |          and, first, as regards its power with respect to the distance
 45 II  |           each other with a certain power. If I hold it at a greater
 46 II  |              they attract with less power; and if I hold it at a greater
 47 II  |             I have here a centre of power which I will not name at
 48 II  |      between two flat surfaces. The power which I thus have of building
 49 II  |            one inch square has such power of attraction in its particles -
 50 II  |           which is of such size and power as to be almost more than
 51 II  |              are the result of this power of cohesion and attraction.~
 52 II  |         glass differing only in its power of cohesion, because while
 53 II  |        merely held together by this power of cohesion, but that they
 54 II  |           going to make use of this power which matter possesses of
 55 II  |            you have this mechanical power of straining, or whether
 56 III |            sufficient to resist the power we bring to bear upon it. [
 57 III |             such a large extent the power of attraction that the solid
 58 III |            added to the ice has the power of causing it to melt, and
 59 III |            all because salt has the power of lessening the attraction
 60 III |            but it certainly has the power of continuing in a better
 61 III |             to this bubble the very power of an India-rubber ball;
 62 III |             bubble, that it has the power of contracting so powerfully
 63 III |         show you to illustrate this power of cohesion of the particles
 64 III |     illustration of the effect of a power of nature which we have
 65 III |          certain amount of this new power at our disposal. Here you
 66 III |            to submit itself to this power; for the moment I put them
 67 IV  |             chlorine unite by their power of chemical affinity, and
 68 IV  |          one great exertion of this power which is known as chemical
 69 IV  |            the evolution of another power of matter - of a power new
 70 IV  |      another power of matter - of a power new to us, and which we
 71 IV  |            We recognize heat by its power of liquefying solid bodies
 72 IV  |    vaporizing liquid bodies; by its power of setting in action, and
 73 IV  |             for the effects of this power. We need not consider many
 74 IV  |      because when you have seen its power of changing ice into water
 75 IV  |             a perfect proof of this power of heat to contract and
 76 V   |           kind to each other - that power which keeps them together
 77 V   |             removing the attractive power by drawing it through his
 78 V   |          shellac, and take away the power, which I can do by drawing
 79 V   |             contain this attractive power; when they were parted,
 80 V   |           which you can evolve this power. When you go home, take
 81 V   |             have a great attractive power, for this little key is
 82 V   |            magnets of extraordinary power). And let us take one of
 83 V   |       examine it, and see where the power is in the mass, and whether
 84 V   |            and whether it is a dual power. You see it attracts these
 85 V   |         that there is an attractive power at the extremities which
 86 V   |          pulls toward it with great power; and, as I carry it round,
 87 V   |           dealing with two kinds of power, attracting different ends
 88 V   |            of the magnet - a double power, already existing in these
 89 V   |           is to express this double power.~Now with this loadstone
 90 V   |             up, so wonderful is its power of attraction. If you take
 91 V   |            magnets that this double power becomes evident principally
 92 V   |             concerned in giving the power. That will at first seem
 93 V   |            the magnet contains this power of attraction and repulsion,
 94 V   |             repulsion, but that the power is only rendered evident
 95 V   |          repulsive. Now is not this power a most wonderful thing?
 96 V   |            than it is; its cohesive power it must and does have; but,
 97 V   |            can add or subtract this power of magnetism, and almost
 98 V   |         silk, and for obtaining the power called electricity; and
 99 V   |             that I can transfer the power from the machine to this
100 V   |            that we can transfer the power of heat from one thing to
101 V   |            one way of obtaining the power of heat) and place it under
102 V   |              Now you are aware that power is being transferred from
103 V   |             very slow conduction of power as compared with electricity.
104 V   |             glass does not lose the power which it acquired when it
105 V   |             with a rod of glass, no power is drawn away, showing you
106 V   |          the conductibility of this power through some bodies and
107 V   |            the top, and you see the power of repulsion with which
108 V   |             can manage to send this power of electricity from place
109 V   |     materials which can conduct the power. Suppose I want to fire
110 V   |             it by this transferable power of electricity. I will take
111 V   |     arrangement which gives us this power, and arrange wires so that
112 V   |             that they may carry the power to the place I wish; and
113 V   |             see how it is that this power of electricity can be transferred
114 V   |             at a loss to bring this power of electricity into comparison
115 VI  |           to see how it is that one power affects another - how the
116 VI  |          strips and apply to it the power of heat, admitting the contact
117 VI  |           it does not take away its power of decomposing the water,
118 VI  |           We have not destroyed the power of chemical affinity, but
119 VI  |           this? The platinum has no power of itself to reduce that
120 VI  |       mysterious way, received this power by its contact with the
121 VI  |             strange manner, we have power to make that chemical force,
122 VI  |             between them, have this power transferred from one to
123 VI  |            whole amount of chemical power there evolved through these
124 VI  |             the spark shows us what power is present; and what a strange
125 VI  |           order to see whether this power from the voltaic battery
126 VI  |            takes place, because the power will cause the gold leaves
127 VI  |             we have here a chemical power which sends forth the spark;
128 VI  |       consider it in its energy and power. And the zinc is being burned
129 VI  |      electric light. That very same power which in that jar you saw
130 VI  |            show that the amounts of power evolved in either case are
131 VI  |     identical. Having thus obtained power over the chemical force,
132 VI  |       illustration of the wonderful power of conveying this force
133 VI  |             is a complete bridge of power. There is metallic connection
134 VI  |          want to show you that this power is still chemical affinity;
135 VI  |       affinity; that if we call the power which is evolved at this
136 VI  |         solution of indigo, and the power of electricity has come
137 VI  |         which is, that the chemical power which destroys the color
138 VI  |            right hand which has the power of destroying the blue,
139 VI  |           liked, without having any power of themselves to reduce
140 VI  |           and now we shall have the power appearing on the left-hand
141 VI  |          and ages ago, by some such power as this. And there is also
142 VI  |           growing by virtue of this power. The lead and the zinc are
143 VI  |             also wonderful in their power of producing another of
144 VI  |      circuit is completed it has no power over the magnet. But observe
145 VI  | illustrations of this high magnetic power. There is that long bar
146 VI  |           it was a magnet. See what power it must have to support
