Hello,

    Hello, Thanks to all who helped with the Coulson quote:

     Someone, I think it may have been Coulson, said, ca. 1952, that calculating
     the energy differenece between two isomers as the difference in their
     computed energies is like weighing the captain by weighing the ship with
     and without him. I would appreciate the reference to this statement.
     [Of course in the 1950's few dreamt that it would ever be possible to
     calculate energy differences to chemical accuracy, at least by ab initio
     methods].

       Thanks
        E. Lewars
