In discussing the nucleus of comets and the role of comets in the evolution of the solar system I summarize the observation only in Table 1, the observed composition. Note that gas-phase chemistry obscures the nature of the active atoms, molecules and radicals in the nucleus.

I wish to stress the fact, so obvious from this symposium, that the comprehensive observational attack on Comet Kohoutek (1973f) has led to an enormous step forward in deciphering the comet enigma.
