         Q.   Is that because there were concerns about the effects of
     2        CFC propellants on the ozone layer?
              A.  I do not know the reason that Congress chose to ban
     3        them at the time.
 
     4   Q.   Would it surprise you if that was the reason, as a
              scientist?  That would have been one of the concerns,
     5        would it, at that time?
              A.  It is possible that is the reason.  The reason I am
     6        being careful is that the quantification of the possible
              problems was not published until 1986 which is when the
     7        first World Meteorological Organisation Report came out.
              If you notice from the documents that we used today, you
     8        can see that even in 1987 people were still putting
              caveats as to what the actual chemical effect of certain
     9        species was.
 
    10   Q.   So were you aware that, for example, environmentalists
              were calling for the banning or the phase out of CFCs from
    11        well before 1985/86, for example, around the aerosols
              issue?  Whether they were right or wrong, were you aware
    12        that was happening?
              A.  I was not particularly aware at that stage of the
    13        environmental lobby because I was not involved with this
              issue until about 1986.
    14
         Q.   Right.  At the back of one of the Ozone Protection Group
    15        documents it has a list of references?
              A.  Yes.
    16
         Q.   Do not have to get our papers out but, just for the
    17        record, on page 449 there is a document by the Department
              of the Environment 1979, Chlorofluorocarbons and their
    18        Effect on Stratospheric Ozone, Pollution Paper 15?
              A.  Yes.
    19
         Q.   Are you aware of that document?  Have you ever seen that
    20        document?
              A.  No.
    21
         Q.   If we go back to the Plastiscope document that was served
    22        this morning?
              A.  Yes.
    23
         Q.   If we remember, it is the July 1987 Modern Plastics
    24        International?
              A.  Yes.
    25
         Q.   Some of it was read out by Mr. Rampton but other bits were 
    26        not.  If I can read out the bit and ask you to comment on 
              it.  From the first paragraph onwards: 
    27
              "Pressure in the US Congress and worldwide to limit
    28        production of chlorofluorocarbons has intensified,
              underscoring the importance of renewed CFC supplier
    29        efforts to develop substitute formulations.  Among those
              affected by growing concern about possible adverse CFC
    30        impacts" -- sorry, at this point can we just clarify, "CFC
              impacts" would have included at that time CFC-22, is that
