In former times, those severe places where the discipline of the prison delivers the convict into his own hands, were composed of four stone walls, a stone ceiling, a flagged pavement, a camp bed, a grated window, and a door lined with iron, and were called dungeons; but the dungeon was judged to be too terrible; nowadays they are composed of an iron door, a grated window, a camp bed, a flagged pavement, four stone walls, and a stone ceiling, and are called chambers of punishment.

从前，狱里的制度是让囚犯自己去处理自己的，囚禁他们的那种严酷的地方，四堵墙是条石砌的，顶上也是条石架的，地上铺了石板，放一张布榻，有一个用铁条拦住的透风洞，一道钉上铁皮的门，这种地方叫做囚牢，但是有人认为囚牢太可怕了。
