Hugh laughed again, and with such thorough abandonment to his mad humour, that his limbs seemed dislocated, and his whole frame in danger of tumbling to pieces; but Mr Tappertit, so far from receiving this extreme merriment with any irritation, was pleased to regard it with the utmost favour, and even to join in it, so far as one of his gravity and station could, with any regard to that decency and decorum which men in high places are expected to maintain.
1841, Charles Dickens, Barnaby Rudge
