''London'' I wander thro'' each charter''d street Near where the charter''d Thames does flow, And mark in every face i meet Marks of weakness, marks of woe In every cry of every Man In every infant''s cry of fear, In every voice, in every ban, The mind-forged manacles i hear. How the chimney-sweeper''s cry Every black''ning Church appalls; And the hapless Soldier''s sigh Runs in blood down Palace walls. But most thro'' midnight streets i hear How the youthful Harlot''s curse Blasts the new born infant''s tear, And blights with plagues the marriage hearse. The stanza form in ''London'' is referred to as
