This is a fascinating 1852 Levasseur map of the French Colonies in Africa.  The map area is divided into three sections dedicated to Senegambie (Senegambia), Madagascar, and the Senegal River.  The largest of these focuses on Senegambia with an inset of the Island of Goree in the lower left.   The map proper is surrounded by elaborate decorative engravings designed to illustrate both the natural beauty and trade richness of the land. There is a short textual history of the region depicted to the left and right of the map. Published by V. Levasseur in the 1852 edition of his  Atlas National de la France Illustree.
