In 1667, Lamoignon, first president of the Parliament of Paris, suggested to Nicolas de La Mare to write a work methodically exposing the police methods applicable in a big city. La Reynie opened all the archives he needed to write it, and Étienne Baluze gave him access to Colbert's rich library. The first volume of the Police Treaty appeared in 17073, Volume 2 in 1710, Volume 3 in 17194. In 1722 the second volume was expanded by an appendix5 on meat (pigs, lambs, kids, suckling pigs) . Aging, he received the help of Lecler du Brillet, King's Attorney at the Admiralty, to write the fourth and final volume, posthumously published in 1738
