First American edition of Patrick Colquhoun's *Treatise on the Police of London*, printed in Philadelphia in 1798 by Henry Sweitzer for Benjamin Davies. This edition includes virulently anti-Semitic passages alongside a detailed examination of London's late-Georgian underworld, covering various crimes, criminals, and social issues. Originally published in London in 1796, this work offers a valuable, albeit biased, sociological perspective on 18th-century London.
