One of the greatest of philosophers, Alexander de Humboldt, so long as 13 years ago, wrote as follows:

"The kingdom of New Spain has one decided advantage over the U. States.-- The number of slaves there, either Africans, or of mixed race, is almost nothing; an advantage which the European colonists have only begun rightly to appreciate since the tragical events of the revolution of St. Domingo.

So true is it that the fear of physical evils acts more powerfully than moral considerations on the true interests of society, or the principles of philanthropy and of justice, so often the theme of the parliament, the constituent assembly, and the works of the philosophers."
