     1        A.  Yes.
 
     2   MR. JUSTICE BELL:  Where is that now?
 
     3   MS. STEEL:   Mine is just loose.
 
     4   MR. RAMPTON:  My Lord, it is tab P.
 
     5   MR. JUSTICE BELL:  Referring to that, can you answer the
              question?
     6        A.  Yes.  P 12 is a histogram which is labelled as fig.
              7.  This gives time to brain failure.  In this context it
     7        was time to loss of the brain to respond to a flash of
              light, so we are measuring the electrical response to an
     8        external stimulus.  And that, as I say, is synonymous with
              profound brain failure.
     9
              In the situation where a superficial cut in the back of
    10        the neck is made, which includes severing the spinal cord,
              we are talking about the fourth bar downwards, where it
    11        says "spinal cord without breathing".  So the time to
              brain failure would be over three minutes.  Now, that
    12        would not be the time to loss of consciousness though.
 
    13   Q.   What would the time to loss of consciousness be, if you
              can tell?
    14        A.  I cannot give you a precise estimate.
 
    15   Q.   The best estimate you can give?
              A.  I would not like to give one.
    16   .
         Q.   Very well.  Might the time to consciousness be as long as
    17        three minutes?
              A.  No, it would be less than three minutes.  It could be
    18        in the range of, say, 20 seconds to as long as two
              minutes; it could be within that range.
    19
         MS. STEEL:   The recommendation that was based on 105
    20        milliamps, you said that----?
              A.  That provided a 52 second period, 52 seconds, before
    21        the first bird in that experiment regained apparent
              consciousness.
    22
         Q.   So you could have birds regaining consciousness before
    23        they actually die?
              A.  In the situation -- is that what you are referring
    24        to?
 
    25   Q.   Yes.
              A.  It depends on the time to consciousness after the neck 
    26        cut, if the animal -- plus the fact they had been stunned 
              before.  It is a very complex situation to give a guess. 
    27
         MR. JUSTICE BELL:  It has been put to you it would be a
    28        possibility.  Obviously, there are variables.  Is it a
              possibility?
    29        A.  It is a possibility.
 
    30   MS. STEEL:   That is at 105 milliamps?
              A.  Sorry, are you referring to 105?
