He drew it nearer, and then rested his arms on the table, and looked at the opposite wall, as I supposed, surveying one particular portion, up and down, with glittering, restless eyes, and with such eager interest that he stopped breathing during half a minute together.
'Come now,' I exclaimed, pushing some bread against his hand, 'eat and drink that, while it is hot: it has been waiting near an hour.' He didn't notice me, and yet he smiled.

I'd rather have seen him gnash his teeth than smile so.
'Mr.Heathcliff! master!' I cried, 'don't, for God's sake, stare as if you saw an unearthly vision.' 'Don't, for God's sake, shout so loud,' he replied.

'Turn round, and tell me, are we by ourselves ?' 'Of course,' was my answer; 'of course we are.' Still, I involuntarily obeyed him, as if I was not quite sure.

With a sweep of his hand he cleared a vacant space in front among the breakfast things, and leant forward to gaze more at his ease.
Now, I perceived he was not looking at the wall; for when I regarded him alone, it seemed exactly that he gazed at something within two yards' distance.

And whatever it was, it communicated, apparently, both pleasure and pain in exquisite extremes: at least the anguished, yet raptured, expression of his countenance suggested that idea.
