 2 I  |          of those things which we call power, or force; and you
 3 I  |           sort of matter which we call water - it is there ice [
 4 I  |       down. That power is what we call gravity, and you see there [
 5 I  |      balance. Here I have what we call a weight [an iron half cwt.] -
 6 I  |       until it arrived at what we call the centre of gravity of
 7 I  |      centred, and that point they call the centre of gravity; it

11 II |          first to make it what we call polarized; but about that
12 III|  illustration (as philosophers we call it all water, even though

17 III|        hydrogen; and the other we call oxygen - that gas which

20 IV |      consideration I would rather call it, of chemical affinity.

22 V  |         silk covered with what we call amalgam, look at the attraction
23 V  |      nature of the force which we call Electricity. There is no
24 VI |     behind me. I am using what we call a Grove's voltaic battery,
