The edict of Measured of January 1644, sets up new a Tax on land royal.

It organizes the toisage (calculation of the area) of the buildings built in the suburbs of Paris in spite of the prohibitions of 1548, renewed in 1627 and 1633. The owners of these buildings must pay a tax of 50 pennies per measuring apparatus of built surface (the Toise is worth approximately 2 meters length).

It causes urban disorders and the Parlement of Paris obtains the exemption for its members, for the lawyer S, the Procureur S, the notary S and the Officier S of the University. The government must give up it in 1645 after a news and vain attempt.
