 A month later, 15 April 1829, the statutes were adopted.These were drawn up much after the pattern of the French society.The only divergent points which need be mentioned were that the society was to be known as the Leopoldine Society -- "Leopoldinenstiftung"—to perpetuate the memory of the Maria Leopoldina of Austria, -Empress of Brazil, a favourite daughter of Francis II, Holy Roman Emperor and wife of Pedro I of Brazil; and that the society should exist only in Austria-Hungary.
