'How do you account for it?'
'I don't account for it at all. I don't pretend to understand it.'
'You think, then, that it was really supernatural?'
'We know so little what Nature comprehends--what are its powers and limits--that we can scarcely speak of anything that happens as beyond it or above it.'
'And you are certain that this did happen?'
'Quite certain; of that I have no doubt whatever.'
