Oliver Twist

The boys polished them with their spoons till they shone again; and when they had performed this operation (which never took very long, the spoons being nearly as large as the bowls), they would sit staring at the copper, with such eager eyes, as if they could have devoured the very bricks of which it was composed; employing themselves, meanwhile, in sucking their fingers most assiduously, with the view of catching up any stray splashes of gruel that might have been cast thereon.†
Chpt 2

Oliver, whose eyes had glistened at the mention of meat, and who was trembling with eagerness to devour it, replied in the negative; and a plateful of coarse broken victuals was set before him.†
Chpt 4 *
