Sire,—The memorial of the Doctor Juan Luis Arias showeth: That in consideration of the great advantage which will accrue to the service of Your Majesty, to the extension of the Catholic Church, and to the increase of our holy faith, from the conversion of the gentiles of the southern land, which is the principal obligation to which Your Majesty and your crown are pledged, he now earnestly begs (great as have been his former importunities) to solicit Your Majesty's consideration to that which is here set forth. At the instance of the fathers of the Seraphic order of St. Francis, and in particular of the father Fray Juan de Silva, he has composed a treatise dedicated to his most serene highness the Infant Don Ferdinand, from which a judgment may be formed of the temperature, productions, and population of the southern hemisphere, and every other point desirable to be understood with respect to its most extensive provinces and kingdoms. He has done this with a view to its discovery, and the spiritual and evangelical conquest, and bringing in to our holy faith and Catholic religion of its numberless inhabitants, who are so long waiting for this divine and celestial benefit at the hand of Your Majesty.
