It is agreed that essentially all the carbon in interstellar space forms CO; it is also shown that the major volatile material other than H2 and He present in the solar system must be CO or substances based on CO. The possibility that sugars were the primary material from which terrestrial volatiles were derived is considered, noting that if all the water of the terrestrial ocean underwent the process of 'coalification', the amount of carbon distributed in the form of graphite in a uniform layer over the whole surface of the earth would be 1 km thick. It is concluded that because graphite is a lubricant and chemical reactions involving carbon at high temperature tend to evolve gases, the carbon could play a significant role in promoting plate tectonics.
