After Cuvier had presented to Buonaparte, in a Council of State, his Report of the Progress of the Mathematical and Natural Sciences since the year 1789, the Emperor expressed, in a very happy manner, the satisfaction which he had received from the document. "He has praised me," said Napoleon, "as I like to be praised." Cuvier, however, as he himself said, had only invited the Emperor to imitate Alexander, and to employ his power in promoting the advancement of the natural sciences.
