'They are very well,' said Stephen, unwilling to open his holsters (a teratoma in one, a bottled Arabian dormouse in the other). 'Do you apprehend any danger?' 'This is an ugly stretch of road, with all these disbanded soldiers turned loose. They made an attempt upon the mail not far from Aker's Cross. Come, let me have your pistols.

'It is an inward wen, a tumour we find them, occasionally, in the abdominal cavity Sometimes they contain long black hair, sometimes a set of teeth this has both hair and teeth. It belonged to a Mr Elkins of the City, an eminent cheese-monger. I prize it much.'
