  1 I  |          shell-lac which acted by attraction, and pulled the paper over;
  2 I  |      power is entirely due to the attraction which there is between the

  4 I  |           these bodies possess an attraction every one toward the other.
  5 I  |           showing clearly that an attraction does exist, just as it did
  6 I  |         the law which governs its attraction (for which, I think, I must
  7 II |           the whole power of this attraction was exerted between their
  8 II |       there was much more of this attraction exerted; or, if I made this
  9 II |        large ball - that then the attraction would become so powerful
 10 II |     greater distance still, their attraction is still less. Now this
 11 II |       millions of miles, this law attraction, or gravitation, still holds
 12 II |      reason of the effects of its attraction at this overwhelming distance.
 13 II |           So it is as regards the attraction of these two balls; they
 14 II |           showed you the electric attraction on the last occasion (through
 15 II |       placed upon it, see what an attraction they have for each other.~
 16 II |        keep close together by the attraction between the particles that
 17 II |            in fact, merely by the attraction of one particle to another,
 18 II |           so far apart that their attraction is too weak to cause them
 19 II |     experiment to prove that this attraction does still exist in those
 20 II |       together in the lump by the attraction between their parts), and
 21 II |            and I can show you the attraction between its separate particles;
 22 II |           this wall is due to the attraction of the particles, forming,
 23 II |         upright wall: is not this attraction most wonderful? That bar
 24 II |          square has such power of attraction in its particles - giving
 25 II |          are held together by the attraction of their particles, and
 26 II |           show how strong is this attraction of the particles. [The lectured
 27 II |     damsels.~How can we make this attraction of the particles a little
 28 II |          properly, will show this attraction. Here is a boy's experiment (
 29 II |         lead hang together by the attraction of their particles, and
 30 II |    particles within the sphere of attraction, you will see how soon they
 31 II |        but simply by means of the attraction of the particles.~This,
 32 II |          board - Cohesion, or the attraction exerted between the particles
 33 II |           these conditions of the attraction of cohesion! how many new
 34 II |      gives us beyond those of the attraction of gravitation! See how
 35 II |        this power of cohesion and attraction.~I have here a body in which
 36 II |         as the red body, only the attraction of cohesion is in a certain
 37 II |           that is all because its attraction of cohesion is changed.
 38 II |         that this is owing to the attraction of the particles one for
 39 II |         may consider as a kind of attraction, and I have arranged a very
 40 II |          out of its course by the attraction of the glass upon it; and
 41 II |        the light by virtue of its attraction, but actually splits it
 42 III|         as it were, by the strong attraction which the particles of alum
 43 III|         we possess of making this attraction alter a little in its force;
 44 III|           of strength, due to its attraction of cohesion; but if Mr.
 45 III|          soft mean? Why, that the attraction between the particles is
 46 III|        block of ice]; because the attraction of the particles to each
 47 III|         large extent the power of attraction that the solid substance
 48 III|     actually rising in steam, the attraction of some of the particles
 49 III|         by destroying some of the attraction which existed between the
 50 III|          increase in their mutual attraction and become ice; and above
 51 III|           certain temperature the attraction decreases and the water
 52 III|        warmer climate, it has its attraction of cohesion so much diminished
 53 III|         diminishing this force of attraction between the particles of
 54 III|        the power of lessening the attraction between the particles of
 55 III|       loses some of that force of attraction by means of which it remains
 56 III|          whenever we diminish the attraction of cohesion we absorb heat,
 57 III|         whenever we increase that attraction heat is evolved. This, then,
 58 III|       liquid they have lost their attraction of cohesion; for here is
 59 III|           particles of which have attraction sufficient to make them
 60 III|           all owing to the strong attraction of the particles of the
 61 III| continuing in a better manner the attraction of the particles (and let
 62 III|       which it is composed has an attraction of particle for particle -
 63 III|         did at last break up that attraction which holds the liquid together,
 64 III|           the liquid diminish its attraction of cohesion; it is now boiling,
 65 III|         necessary to increase the attraction of the particles by cold
 66 III|       giving them this diminished attraction, that if I were to take
 67 III|          foot], so greatly is the attraction of cohesion diminished by
 68 III|         this consideration of the attraction of the particles for each
 69 III|           different manner to the attraction of gravitation or cohesion,
 70 III|         or cohesion, and this new attraction we call chemical affinity,
 71 III|         longer concerned with the attraction of iron for iron, water
 72 III|      dealing with another kind of attraction - the attraction between
 73 III|          kind of attraction - the attraction between particles of a different
 74 III|  different kinds, and it is their attraction to each other which makes
 75 IV |          the subject. Besides the attraction which there is between its
 76 IV |         consideration of chemical attraction, I must enlarge your ideas
 77 IV |        substances which have this attraction for each other; for it changes
 78 IV |           affinity overcoming the attraction of cohesion of the particles.
 79 IV |       them, I shall have chemical attraction take place. I will pour
 80 IV |           chemical affinity. This attraction between different particles
 81 IV |        and its amount of chemical attraction or affinity is just as strikingly
 82 IV |          or exceeded than can the attraction of gravitation. You might
 83 IV |  substance. It is by this kind of attraction of the different particles
 84 V  |     Remember that we spoke of the attraction by gravitation of all bodies
 85 V  |     Remember that we spoke of the attraction of particles of the same
 86 V  |           beyond the first simple attraction of gravitation, because
 87 V  |         because here we deal with attraction between different kinds
 88 V  |       To-day we come to a kind of attraction even more curious than the
 89 V  |        than the last, namely, the attraction which we find to be of a
 90 V  |          endowed with a wonderful attraction, which is not found in them
 91 V  |      piece of shellac, having the attraction of gravitation, having the
 92 V  |           gravitation, having the attraction of cohesion, and if I set
 93 V  |          to it, it would have the attraction of chemical affinity to
 94 V  |         by a thread]. There is no attraction between this ball and this
 95 V  |       ball about, but there is no attraction. But if I rub the shellac
 96 V  |       near the ball], look at the attraction which has arisen out of
 97 V  |         call amalgam, look at the attraction which it has; how it draws
 98 V  |          it through the hand, the attraction will be all removed again,
 99 V  |           of shellac, and make it attraction by friction; and remember
100 V  |          that, whenever we get an attraction of gravity, chemical affinity,
101 V  |         are actually two kinds of attraction concerned in this case,
102 V  |         have here, then, a double attraction - a dual attraction or force
103 V  |        double attraction - a dual attraction or force one attracting
104 V  |       together again, there is no attraction; it has all disappeared [
105 V  |            you see how strong the attraction is; I can even draw it about.
106 V  |     discover the presence of this attraction. There is scarcely a substance
107 V  |        from Sweden. They have the attraction of gravitation, and attraction
108 V  |    attraction of gravitation, and attraction of cohesion, and certain
109 V  |    cohesion, and certain chemical attraction; but they also have a great
110 V  |          Now that is not chemical attraction; it is not the attraction
111 V  |         attraction; it is not the attraction of chemical affinity, or
112 V  |         it is a separate and dual attraction, and, what is more, one
113 V  |           we come to examine this attraction a little more closely, we
114 V  |     places in which this force of attraction resides? If I take this
115 V  |         force, then, is no longer attraction, but repulsion; but, if
116 V  |           bring it near, it shows attraction again.~You will see this
117 V  |         effect upon it, either of attraction or repulsion, until, as
118 V  |        which takes up the form of attraction and repulsion. And now,
119 V  |          in order to increase the attraction. This mass will lift that
120 V  |         wonderful is its power of attraction. If you take a needle, and
121 V  |          get all the phenomena of attraction and repulsion by bringing
122 V  |     magnet contains this power of attraction and repulsion, but that
123 VI |           that there will be some attraction between those leaves even
