It does remind me, speaking of royalty, however, that on 14^th November 1948, I was returning from the laboratory, in time on this occasion, before 10.30 that is to say, and the gate was already shut, but it was opened by the head porter, and he doffed his bowler hat and said, 'Good evening, sir, it's a boy'. And so I said, 'What's a boy?' And he said, 'The young princess, sir, she's had a baby son'. 'Oh', I said, 'I didn't even know she was pregnant', and for a moment, a slight disrespect for... horror came over the chief porter's face, the head porter's face, and then he said, 'Yes indeed, sir, a boy'. So that was Prince Charles being born.

But, as I said, I think they are, withal, able to do first rate... well, science is really all I can judge, but the science that was being done at that time was top rate, and is obviously still the same.
