This essay is accompanied by another, written two years earlier, entitled, "Consideration of the means by which the present highly advanced state of learning and civilisation in Europe can be most effectually communicated to the rest of the world and to our Indian empire in particular; Kotah, May 21,1830."

This volume, written between May 3 and December 2, includes essays on mineralogy, the vegetable kingdom (such as botany and fruitification), and the animal kingdom (such as zoology, ornithology, and generation of animals).

This volume contains reports made for the Académie des Inscriptions et Belles Lettres on such topics as astronomy, geometry, and natural history.
