     1        article in Nature, do you?
     2        A.  Not here.
     3
     4   Q.   No, but do you have it somewhere?
     5
     6   MR. RAMPTON:  My Lord, in one of Professor Wheelock's
     7        statements he actually quotes from the Willett article
     8        which makes reference to what appears to be that paper.
     9        So, at any rate, the first publication of that paper must
    10        have preceded 8th June 1983 which is when Professor
    11        Wheelock's statement was prepared.  What I cannot find at
    12        the moment is the Willett study which makes mention of
    13        that Chinese study.
    14        A.  It was published in Nature.
    15
    16   MR. RAMPTON:  There is one in 1989.  I can give the reference
    17        to that because it is in Willett's 1990 paper, in the New
    18        England Journal of Medicine.  It is reference 50.
    19
    20   THE WITNESS:  In fact, the actual fat intake that Professor
    21        Willett quotes in article in Nature is different to the
    22        fat range which is quoted in this particular letter from
    23        Professor Campbell or Dr. Campbell.
    24
    25   MR. JUSTICE BELL:  Could I just have a look at it?  (Handed).
    26
    27   THE WITNESS:  So either the estimation of the fat has changed
    28        through time or an error has crept in.
    29
    30   MR. JUSTICE BELL:  You had better have it back. (Handed).
    31
    32   MR. MORRIS:  We will try to get a better copy.  I have made
    33        this point before.
    34
    35   MR. JUSTICE BELL:  Ask your question again.
    36
    37   MR. MORRIS:  Having seen that, if it is true, what I said from
    38        his letter, that would be an advantage of a population
    39        study over a cohort study?
    40        A.  Well, I would still argue that, in fact, all that does
    41        is point you in a direction and you would need to -- you
    42        know, I would like to know what the methodology was that
    43        looked at that particular study.  In fact, in this letter
    44        you have given me from Dr. Campbell he states that, of
    45        course, the higher breast cancer rates are not due solely
    46        to dietary fat but to a broad constillation, I presume he
    47        means, of dietary factors associated with these levels of
    48        dietary fats.  So, he is actually indicating that it is
    49        not just a straightforward association; it is a complex
    50        relationship. 
    51 
    52   Q.   But he is saying that diet and specifically dietary fat 
    53        play a part, an essential part?
    54        A.  He obviously believes that, yes.
    55
    56   Q.   I do not know if there is much more value to be gained
    57        from going through a number of studies really.  There was
    58        one interesting study which was your reference No. 2 which
    59        actually is a summary of studies.
