DUBOIS (P.). Atlas of the map of Paris divided by arrondissements. Prepared by P. Dubois Ing.r geometrician. S.l., 1863. - In-plano manuscript atlas. In sheets, modern slipcase with blue morocco back , blue morocco title piece on the first plate. Precious and probably unique handwritten atlas comprising a title and 20 plans of the arrondissements of Paris, 9 of which are on double pages mounted on canvas. This plan was executed by the surveyor P. Dubois in 1863. The latter restores the 20 districts as they were delimited by the law of June 16, 1859 within the framework of the annexation of the suburbs located between the enclosures of the General Farmers and Thiers. The borders of the boroughs are painted red and the Seine is painted blue. A map of Neuilly-sur-Seine engraved by Brindot after Dubois is known, but this map of Paris seems never to have been published. Wetnesses and stains on the title, wetnesses in the upper margin of the shots.
