     1        the stunning area to try and improve that situation, and
     2        this is some of the more recent work that we have done with
     3        MLC in gauging the actual performance of the equipment.
     4        Unfortunately, the people who we were working with at this
     5        time have had, we and MLC were working with, have had
     6        financial cramp.

     8   Q.   There is not a great deal I want to ask you about these
     9        documents, Mr. Bowes, because it might be thought they
    10        speak for themselves.  "Impedance" in the 4th line, if you
    11        just look at the first page, is what otherwise we may call
    12        "resistance expressed in ohms"; is that right?
    13        A.  Yes.
    14
    15   Q.   You will have noticed from Mr. Dr. Gregory's report that he
    16        assumed the resistance in the head of pig as starting as
    17        300 ohms?
    18        A.  That is correct.
    19
    20   Q.   Whereas here we see a range round about 170 up to 178
    21        I think is the highest?
    22        A.  Yes.  We believe that is due to our watering of pigs,
    23        or our spraying of pigs.
    24
    25   Q.   So your belief is that by spraying pigs and improving the
    26        conductivity, you reduce the resistance?
    27        A.  That is our belief, sir.
    28
    29   Q.   Who actually made these measurements?
    30        A.  The Meat and Livestock Commission.
    31
    32   Q.   Was that one person, or two, or what?
    33        A.  In the Meat Livestock Commission there would be a
    34        minimum of two, also the people who were manufacturers of
    35        that equipment, and obviously our technical team would be
    36        involved as well.
    37
    38   Q.   We notice that ----
    39        A.  -- May I say also undoubtedly a veterinarian would be
    40        shown particular interest at that time as well.
    41
    42   Q.   We notice if we look at the sheets, and I am not going
    43        through them all, the current within one second expressed
    44        in amps ranges from 1.34, that is the penultimate sheet,
    45        down to 1.1 which is the third sheet I think.
    46        A.  That is correct.
    47
    48   Q.   The first question is this:  Why does the "current within 1
    49        second matter"?  Why give that figure, "current within one
    50        second"? 
    51        A.  Because when one applies the tongs, one must measure 
    52        immediately. 
    53
    54   Q.   Sorry?
    55        A.  When one applies the tongs, one must measure
    56        immediately.
    57
    58   Q.   Does that 1 second amperage continue to apply throughout
    59        the time that the tongs are on the pig's head?
    60        A.  Yes.
