 1 I  | position of the ball at the two ends of its journey, you see
 2 III|      you see it is [causing the ends of the wires to touch] -
 3 V  |         you see that one of its ends repels the suspended magnet;
 4 V  |          and I have colored the ends differently, so that you
 5 V  |     power, attracting different ends of the magnet - a double
 6 V  | artificial magnet in which both ends have been brought together
 7 V  |        and just draw one of its ends along one extremity of the
 8 V  |         I have now made the two ends magnetic in opposite ways.
 9 V  |        half way between the two ends. But now, if I break out
10 V  |          joined together at the ends, and wrap a piece of paper
11 VI |       than just bring these two ends in contact, when the spark
12 VI |       gold leaves with separate ends of this battery, and if
13 VI |       in communication with the ends of the battery, they will

15 VI |         spark. I take these two ends and bring them together,
16 VI |        of wires to the opposite ends of the battery, and bring
17 VI |       any difference in the two ends of the battery, and which
