         Q.   Do you know which publication it is from?
     2        A.  My reading of this document is that it is a document
              that he produced following a debate that he had at a
     3        university, the University of Missouri, Kansas City, where
              he had a debate with -- well, I am not sure if it says
     4        that, but in any case he debated about the benefits of
              polystyrene foam packaging, and what he did in the
     5        document is do a literature review -- by "literature
              review" I mean he reviewed the scientific literature
     6        related to -----
 
     7   Q.   On this subject?
              A.  Related to the migration of various types of materials
     8        from plastic packages into food contained by these
              packages.  He was specifically interested in those studies
     9        which focused on styrene migration.  I refer to the
              references on page 13 of that item.
    10
         Q.   Ten pages of references or something, nine pages of
    11        reference?
              A.  I would say four really, but these documents are
    12        referred to within the paper -- I have a couple of quotes
              that I call your attention to.
    13
         Q.   Which pages would they be on?
    14        A.  We will start with page 3 where Mr. Baggett makes
              reference to ----
    15
         Q.   Which paragraph?
    16        A.  Well, these issues, I suppose, go to -- at least in
              the second paragraph -- are related more generally to
    17        storage as opposed to migration.  The last sentence in the
              second paragraph says:  "One of the only problems with
    18        storing large quantities of polystyrene in a closed
              building is emissions from residuals of styrene monomer".
    19        He makes reference to item 10 in the reference list; item
              10 being Polystyrene Safety Data Sheet, Canadian Centre
    20        for Occupational Health & Safety.
 
    21   Q.   Shall we come to the bit about food migration on this
              sheet?
    22        A.  OK.  On page 4 under the heading:  "What about
              Migration of Monomer into Food Products"?  By monomer,
    23        Mr. Baggett is referring to the styrene monomer which is
              the precursor to polystyrene, in which he states:
    24        "Migration of monomers" -- this is the second paragraph
               -- "into food and cosmetics came to a head in the late
    25        1960's and early 1970's with the discovery that vinyl
              chloride monomer is a carcinogen.  It continued in the 
    26        1970's with the suspicion that acrylonitrile used in 
              beverage containers was a carcinogen, which resulted in a 
    27        1975 ruling restricting use of these monomers.  The
              earliest work on styrene migration I found was done in
    28        1972.  Therefore the topic is not new.  A preliminary
              search of the literature suggests that the topic of
    29        migration of styrene monomer was addressed in a 1976
              symposium on health hazards in the plastics industry.  In
    30        the last couple of years since the results of the adipose
              tissue survey were released to the public there has been
