This is an extract from a manuscript and is divided into three parts. This volume puts forth the theory that the visible geological formations of the earth were formed in the depths of the ocean; it offers opinions that support this system; and then predicts the natural consequences of the loss of all living beings from the waters of the ocean.

Founded in Cap François, Saint Domingue (now Haiti) in August 1785, the Cercle des Philadelphes was one of the most prestigious colonial learned societies of the Ancien Regime. During its brief seven year existence, the Cercle pursued an agenda of promoting improvements in agriculture, manufactures, the arts and sciences, published five volumes of memoirs, and established correspondence with their peers in the American Philosophical Society and other learned societies. Their foreign membership included both Benjamin Franklin and Benjamin Rush. The Cercle des Philadelphes Collection is a small, but important assemblage of documents relating to French colonial science. Each of the documents is associated with Louis Narcisse Baudry de Lozières, the first president of the Cercle, including three certificates appointing him to office, and two important addresses. The first of these appears to be his opening remarks to the Cercle at its first public meeting on Aug. 15, 1784. The second is an early, but undated document outlining the organization of the Cercle and its aims.
