Day 103 - 14 Mar 95 - Page 50


     
     1   MS. STEEL:  So if you were cutting the external ones then the
     2        bleeding could occur, the bleed out?
     3        A.  The main bleed out is from the external carotid artery.
     4
     5   Q.   So he could well be saying that you are not cutting the
     6        internal ones which are the ones that are important for
     7        cutting off blood supply to the brain?
     8        A.  It is possible but I do not really know how significant
     9        that internal one is.
    10
    11   Q.   If you could turn to page 250, please?
    12
    13   MR. JUSTICE BELL:  Yes, see what he says there.
    14
    15   MS. STEEL:  Right in the middle of that paragraph.
    16        A.  OK.
    17
    18   Q.   Would you accept what he has written there?
    19
    20   MR. JUSTICE BELL:  I find it very difficult.  Please help me,
    21        Ms. Steel, if you can, but it says -- I regret I have not
    22        noticed this before -- "The neck cut was usually severing
    23        an external carotid artery, a vertebral artery and the
    24        spinal cord".  Then it goes on to say:  "In no birds
    25        examined was either of the two common carotid arteries
    26        cut".  The common carotid arteries are the external carotid
    27        arteries, you can call them one or the other, but it is the
    28        same vessel or the same vessels?
    29        A.  Yes.
    30
    31   MS. STEEL:  He must be talking about the internal ones being the
    32        common ones.
    33
    34   MR. JUSTICE BELL:  Well ----
    35
    36   THE WITNESS:  I would not have thought so but, anyway, the
    37        statement seems to be contradictory.
    38
    39   MR. JUSTICE BELL:  If that is what he meant, if Ms. Steel's
    40        hunch is correct, that would be consistent with what you
    41        have said yourself, that you do not cut the internal common
    42        artery.
    43        A.  That is right, yes.
    44
    45   Q.   I have said it myself now -- you do not cut the internal
    46        carotid arteries, if he is calling them the "common carotid
    47        arteries" -- it does not matter which of you has your
    48        terminology right ----- that would be consistent with what
    49        you are saying?
    50        A.  Yes. 
    51 
    52   MS. STEEL:  In that situation the blood would still be pumped to 
    53        the brain for a period following neck cutting?
    54        A.  Well, it is going to be very, very short, and if the
    55        bird is unconscious it is going to be a very short time.
    56
    57   Q.   But you are not able to tell whether it is conscious or not
    58        because you have severed the spinal cord in 83 per cent of
    59        the birds?
    60        A.  Well, if the spinal cord gets severed at the same time
