 2 I  |        bubbles and ascending in vapor there is absolutely different
 3 I  |         the invisible steam, or vapor, or gas which came from
 4 I  |         another, this steam, or vapor, or gas is, like all other
 5 III|      liquid form, but escape as vapor. At the same time, you see
 6 III|    apply heat to it, it becomes vapor; and I want to show you
 7 III|      and I will set fire to the vapor, so that you may be enabled
 8 III|       but in converting it into vapor; and if I desired to catch
 9 III|         I desired to catch this vapor and condense it (as I could
10 III|       body when in the state of vapor. Here is a substance which
11 III|   became filled with the violet vapor], and you see the same kind
12 III|         is the violet - colored vapor from this black substance,
13 III|       rather the mixture of the vapor with air (for I would not
14 III|        entirely filled with the vapor of iodine).~If I had taken
15 III|   mercury and converted it into vapor (as I could easily do),
16 III|      have a perfectly colorless vapor; for you must understand
17 III|       oxygen, when the dark red vapor of hyponitrous acid was
18 III|        see we can have a violet vapor or an orange vapor, and
19 III|       violet vapor or an orange vapor, and different other kinds
20 III|        different other kinds of vapor, but they are always perfectly
