 5 II |    various chemical elements and chemical compounds contain certain

 8 III|    carbon - that is to say, in a chemical process. The burning of

11 III|       result we must expect from chemical action. When carbon and
12 III|     combustion - that is, in the chemical combination of hydrogen
13 III| decomposition of water begins, a chemical process takes place simultaneously
14 III|         While we there reproduce chemical affinity which is capable

18 III|      overcome chemical forces by chemical forces, through the instrumentality

25 III|        up we must consume either chemical or mechanical forces, or
26 III|      currents.~We have seen that chemical forces, when they come into
