I wondered whether it was a dog or a rat.

The doubt was soon resolved.

A human form reared itself up from the bench against the wall, where it had been lying, not asleep indeed, but half unconscious; and to our great surprise, it turned out to be Mr.
Cattell, who had surrendered to his bail at the same time as we did, and had been shivering there ever since ten o'clock.

After we left him he continued shivering for three or four hours longer in that black-hole of the Old Bailey, which struck a chill into our very bones even in the brief period of our tenancy, and which could hardly be warmed by any conflagration short of the last.

It appeared damp as well as cold, and a sinister effluvium came from a place of necessity at the back.
