 1 IV    |         put into this retort some zinc, water, and oil of vitriol,
 2 VI    |           here is a piece of fine zinc foil, and if I cut it into
 3 VI    |           is to hold the piece of zinc at the side of the flame,
 4 VI    |         it; there is the piece of zinc burning just like a piece
 5 VI    |           brighter. A part of the zinc is going up into the air
 6 VI    |      affinity exerted between the zinc and the oxygen of the air.
 7 VI    |           discussed. Here is some zinc (I keep to the metal zinc,
 8 VI    |         zinc (I keep to the metal zinc, as it is very useful for
 9 VI    |       hydrogen gas by putting the zinc and sulphuric acid together,
10 VI    |           gives us hydrogen - the zinc is pulling the water to
11 VI    |       mercury is spread over that zinc, it does not take away its
12 VI    |           Here are some pieces of zinc covered with mercury exactly
13 VI    |    exactly in the same way as the zinc in that retort is covered;
14 VI    |          introduce along with the zinc another metal which is not
15 VI    |         to put to the amalgamated zinc in this retort some portions
16 VI    |        combustible a metal as the zinc), and observe how I get
17 VI    |        and faster in the jar; the zinc now is acting by reason
18 VI    | abundantly does not come from the zinc, as it did before, but from
19 VI    |         piece of this amalgamated zinc into it, and leave it there,
20 VI    |        its contact with the metal zinc, Here, then, you see a strange
21 VI    |           chemical force from the zinc is transferred and made
22 VI    |      solution, but the moment the zinc was introduced and touched
23 VI    |         force of the particles of zinc acting, and yet, in some
24 VI    |    chemical force travel from the zinc to the platinum by this
25 VI    |           liquid and the slips of zinc and platinum or copper,
26 VI    |           and another, and put in zinc and platinum, zinc and platinum,
27 VI    |         put in zinc and platinum, zinc and platinum, zinc and platinum,
28 VI    |      platinum, zinc and platinum, zinc and platinum, and connect
29 VI    |   platinum of one vessel with the zinc of another, the platinum
30 VI    |           of this vessel with the zinc of that, and so on, we should
31 VI    |    battery, in which one metal is zinc and the other platinum;
32 VI    |         the chemical force of the zinc - its very force carried
33 VI    |          to take a portion of the zinc and burn it in oxygen gas
34 VI    |         energy and power. And the zinc is being burned in the battery
35 VI    |          in that jar, because the zinc is there dissolving and
36 VI    |          actual combustion of the zinc in oxygen, is carried along
37 VI    |         please, consider that the zinc is burning in those cells,
38 VI    |         really the burning of the zinc in the cells behind me;
39 VI    |     effects and powers of burning zinc. I have a few wires here
40 VI    |        this is the heat which the zinc would give if burnt in oxygen;
41 VI    |      metal, when the platinum and zinc were both put in it together.
42 VI    |           power. The lead and the zinc are combined together in
43 VI(25)|     bottle, and fasten a plate of zinc round them just as they
44 VI(25)|        from the cork, so that the zinc may be in contact with every
