Considered to be the best book on California prior to the American occupation. Wheat calls the large map "a landmark...It made these western regions known in European official circles...his highly original map has much to commend it." Wheat neglects to mention the similarities between this map and the John Arrowsmith Map of British North America, 1837 edition. While not a copy of the Arrowsmith, it clearly followed the Arrowsmith map in most areas. The atlas volume contains, in addition to the large map, plans of ports from Acapulco to the Aleutians, including San Diego, Santa Barbara, Monterey, San Francisco, and the mouth of the Columbia. The chart of San Francisco Bay is based on Beechey's chart of 1833, improved by de Mofras' own explorations, particularly in the north bay. This copy belonged to the Prince of Coburg, with a presentation inscription from the author. The large map is hand painted in outline color, all others are without color. Covers of the volumes are half leather dark green cloth covered boards with a crown embossed on the front in gilt. The title "De Mofras. Mexique. Californie. Oregon. 1" is stamped in gilt on the spine of volume one, "... 2" on volume two, and "...Atlas" on the atlas. Rare.
