CHAIRPERSON
Thank you.  Mr Visser has asked if he can ask a question arising out of that, but you can go ahead and ask, Mr Visser.
FURTHER CROSS-EXAMINATION BY MR VISSER
Professor, it is actually something I forgot and not arising from my learned friend, Mr Wills' questions.  May I ask you, can you give us some assistance as far as DNA testing is concerned, because I've only got one question in that regard.  Perhaps I should ask you the question, and you can tell us whether you can help us or not.
