Apology accepted - but Jim, you write at 27 Oct 17 - 12:45 PM and elsewhere about assisting and presenting material at Ireland's top seats of learning. I can only hope that you give more concern to the views others, less rigidity, more open-mindedness, greater care in quoting others, more attention to detail in what you write than you have shown here. I mean where exactly is Luimerick University? You cannot go on blaming your keyboard,
