FIRST EDITION IN ENGLISH, translated from the first edition of 1829 in French. "Barbé-Marbois represented France in the preliminary negotiations with the United States on the Louisiana Purchase and his book is one of the main sources on that subject. It shows that in the claim by the United States in the negotiations with Great Britain, that the northern boundary of Louisiana included the area now comprised in Oregon, Washington and Idaho was without foundation" (Streeter).
