 2 I  |      laden with quicklime taking fire in the middle of the river,
 3 III|      part of this red-hot in the fire, we shall then find that
 4 III|        ice in a quart pot by the fire and freeze it to the stool.
 5 III|          they set the pot by the fire, just to make the result
 6 III|          boiling, and I will set fire to the vapor, so that you
 7 III|      from F) pass. We will there fire it by the electric spark,
 8 III|          H) which burns [setting fire to the gas]; but what comes
 9 III|          bodies. I will just set fire to the point of this little
10 III|       not burn, it does not take fire as the hydrogen would; but
11 III|          in a dazzling stream of fire, so powerfully does the
12 III|         iron filings, which took fire and fell through with beautiful
13 IV |       think you will see it take fire - not with a bright light;
14 IV |     sulphuric acid, when it took fire, and burnt gradually and
15 IV |          mass, and setting it on fire, and throwing it into such
16 IV |          coals on and lights the fire: the substances wait until
17 IV |        and that lead do not take fire while they are lying on
18 IV |      expect you will see it take fire at once. This has been made
19 IV |    whereupon it immediately took fire.] Look! look at the lead
20 IV |         burning! Why, it has set fire to the paper! Now that is
21 IV |      piece of phosphorus and set fire to it, and then place a
22 IV |        oxygen; but suppose I set fire to this piece of cotton
23 IV |          how that burns [setting fire to a piece]; it is very
24 IV |          them hot enough to take fire; and such things have been
25 IV |       hard as to set the tree on fire. I do not suppose I shall
26 IV |      these two pieces of wood on fire by friction, but I can readily
27 IV |           which immediately took fire.] And if you take a smooth
28 IV |        the compression of air to fire the ether-vapor.~This, then,
29 V  |        of cohesion, and if I set fire to it, it would have the
30 V  |          I pout my hand near the fire it becomes hot. I can show
31 V  |         brought red-hot from the fire. If I press this wire to
32 V  |          on the copper will take fire before that on the wood

34 V  |          discharging rod I shall fire the gunpowder [the connection

36 VI |       into a basin and set it on fire; and, having our flame,
37 VI |          even less time to catch fire than gunpowder. [As soon
