11 III    |         Anderson has prepared some oxygen, and we will proceed to
12 III    |          plunge it into the jar of oxygen, and you will see what this
13 III    |            that will not happen in oxygen gas; you will see how differently
14 III    |           introduced into a jar of oxygen.] Look at that! See how
15 III    |             so powerfully does the oxygen support combustiot. Again,
16 III    |            if I may so call it, of oxygen. I have here a circular
17 III    |         effect produced by air and oxygen. If I take this ring flame,
18 III    |            the flame over a jar of oxygen [the experiment was repeated
19 III    |         was repeated over a jar of oxygen, when the combustion of
20 III    |      filings as they fell into the oxygen became almost insupportably

22 III(16)|         air, by combining with the oxygen of the latter to form hyponitrous
23 III(16)|           composed of two parts of oxygen and one part of nitrogen;
24 III(16)|        nitrogen and three parts of oxygen.
25 IV     |        considered the character of oxygen, of which I have here two
26 IV     |        which I have here two jars (oxygen being those particles derived
27 IV     |        appearance exactly like the oxygen we obtained yesterday.~The
28 IV     |           other properties. Unlike oxygen, which is a supporter of
29 IV     |            entirely different from oxygen; it is extremely light;
30 IV     |       one-eighth the weight of the oxygen. I carry this jar upside
31 IV     |                           Whenever oxygen and hydrogen unite together
32 IV     |         been able to reduce either oxygen or hydrogen to the liquid
33 IV     |            experiment of combining oxygen and hydrogen to form water
34 IV     |         formed by the union of the oxygen of the air with the hydrogen
35 IV     |            instance: here are some oxygen particles, and here is a
36 IV     |          carbon particles into the oxygen; they can act, but they
37 IV     |        substance, gaseous like the oxygen, and if I put these particles
38 IV     |    affinity between the carbon and oxygen, for the moment I choose
39 IV     |         introduced into the jar of oxygen, when the combustion proceeded
40 IV     |          combustion of charcoal in oxygen? You must understand that
41 IV     |      thrown off white hot into the oxygen, and burning in it most
42 IV     |           some charcoal burning in oxygen. Well, a piece of lead will
43 IV     |         piece of lead will burn in oxygen just as well as the charcoal
44 IV     |          will act at once upon the oxygen as the copper did in the
45 IV     |       light it and put it into the oxygen, it will burn away just
46 IV     |          in the common atmospheric oxygen at the ordinary temperature.
47 IV     |           atmosphere a part of the oxygen there present, and have
48 IV     |          iron burning very well in oxygen, and I will tell you the
49 IV     |           lead and the atmospheric oxygen; and the reason why this
50 IV     |            stops the action of the oxygen - putting a varnish, as
51 IV     |           of potash containing the oxygen which we found yesterday
52 IV     |           from it; it contains the oxygen there combined and held
53 IV     |          enough to say for want of oxygen.~This, therefore, leads
54 IV     |          the inquiry as to whether oxygen can do more than a certain
55 IV     |        certain amount of work. The oxygen there can not go on burning
56 IV     |           of force exerted by this oxygen. And when I pointed out
57 IV     |            that eight by weight of oxygen to one by weight of hydrogen
58 IV     |    hydrogen to combine with six of oxygen, or ten of oxygen to combine
59 IV     |           six of oxygen, or ten of oxygen to combine with six of hydrogen;
60 IV     |      hydrogen; it must be eight of oxygen and one of hydrogen. Now
61 IV     |       which the cotton has for the oxygen; but suppose I set fire
62 IV     |         have limited the supply of oxygen, and the inside is prevented
63 IV     |          from having access to the oxygen, just as it was in the case
64 IV     |         which has been imbued with oxygen in a certain manner. I need
65 IV     |        from the other, because the oxygen which must be present in
66 IV     |      imbued with bodies containing oxygen. Here is some which has
67 IV     |         goes on independent of the oxygen of the atmosphere. And here
68 IV     |  atmosphere with shot, and yet the oxygen which it contains supplies
69 IV     |            the requisite amount of oxygen being contained within the
70 V      |         hydrogen could attract the oxygen and reduce it to water,
71 V      |           chemical affinity to the oxygen in the atmosphere. Now all
72 VI     |           between the zinc and the oxygen of the air. I will show
73 VI     |            the zinc and burn it in oxygen gas for the sake of showing
74 VI     |           the actual combustion in oxygen gas of some of this metal. [
75 VI     |           introduced into a jar of oxygen, when it burnt with a brilliant
76 VI     |          combustion of the zinc in oxygen, is carried along these
77 VI     |        zinc would give if burnt in oxygen; but, as it is being burnt
78 VI(24) |     liberated hydrogen withdrawing oxygen from the indigo, thereby
