 1 I  |        shall have to refer. For instance, here is water - it is heavy;
 2 I  |  properties of water. Here, for instance, is some quicklime, and
 3 II |         thing - this stone, for instance [taking a piece of mica12],
 4 II |       and we will, in the first instance, put a piece of common glass
 5 III|       particles of liquids. For instance, what would you propose
 6 IV |         to illustrate this. For instance, if I blow soap bubbles
 7 IV |  knowing it. Take a candle, for instance, and a clean silver spoon (
 8 IV |        flame than in the former instance.] Observe this chemical
 9 IV |    gravitation or cohesion. For instance: here are some oxygen particles,
10 V  |       their ordinary state. For instance, here is a piece of shellac,
11 VI |          therefore, you have an instance in which these two powers
12 VI | hydrogen again, as in the first instance; there, the bubbles are
13 VI |         stops. Here is a better instance to enable some of you to
14 VI |        circuit.~Here is another instance. I will take a piece of
15 VI |     place.~Here we have another instance of chemical action. I take
