ZENON DE ROUVROY, Charles Albert (zay-nong), French author, born in Dreux in 1698; died in Paris in 1759. He was a member of the Academy of Caen, and frequented the literary salons of the time, among them that of Madame Doublet de Per-sau, of whom he was secretary for several years. He obtained later an office in the navy and colonial department, and wrote the instructions for the colonial g'overnors. His books include "Let-tre sur les colonies Francaises de l'Amerique," an anonymous work, which was widely read and caused much discussion, as the author predicted the capture of the colonies by the English (Amsterdam, 1732)" "Memoire sur la politique des Jdsuites dans les pays de l'Amerique" (1735) . " Histoire de la compagnie des Indes" (2 vols, 1738); and "Md-moire historique sur la Louisiane et la compagnie du Mississippi" (1741). The last is a very curious work, which contains interesting information about the operations of John Law and the policy of the Mississippi company. The latter caused all available copies of the work to be destroyed, and it is now extremely rare. Zdnon also wrote "Discussion suceinte sur les operations de la compagnie des [ndes Occidentales" (1751).
