_Papal Bulls of 1493_.--The originals of the bulls of May 3 and 4 exist in the archives of the Vatican; and authenticated copies are in the Archivo general de Indias at Seville, their pressmark being "Patronato, Simancas--Bulas; Est. 1, caj. 1, leg. 1." The Archivo Nacional of Lisbon (which is housed in the Torre do Tombo) has one of the originals of the Bull of May 4--pressmark, "Gaveta 10, maco 11, n°. 16." The _Inter cætera_ of May 3 was not known to be in existence until 1797, when it was discovered by Muñoz in the Simancas archives (from which many documents have since been transferred to the archives at Seville); in recent years it has been found in those of the Vatican also. There is in the British Museum a MS. copy (in Spanish translation) of the Bull of May 4--its pressmark being "Papeles varias de Indias, 13,977." The Bull of September 25 is known only through the Spanish translation made (August 30, 1554) by Grecian de Aldrete, secretary of Felipe II of Spain; this is at Seville, with pressmark as above. Harrisse could not find the Latin original of this document at Simancas Seville, or Rome. For the bulls of May 3 and 4 our translation is made from the Latin text given in Heywood's _Documenta selecta et tabulario secreto Vaticano_ (Roma, 1893), pp.14-26; that contains also photographic facsimiles of the original bulls. Certain formal ecclesiastical phrases which Heywood only indicates by "etc." have been, for the sake of completeness, translated in full in the first bull. The bulls are also published in Raynaldi's _Annales ecclesiastici_ (Lucæ, Typis Leonardi Venturini, MDCCLIV), xi, pp. 213-215; Hernaez's _Coleción de bulas, breves_, etc. (Bruselas, 1879), i, pp. 12-16; _Doc. inéd. Amér. y Oceania_, xxxiv, pp. 14-21; and in _Fonti Italiani_ (Roma, 1892), part iii. The bull _Inter cætera_ of May 3 may also be found in Navarrete's _Col. de viages_, ii, pp. 23-27 (ed. 1825; or pp. 29-33, ed. 1859); _Eximiæ_ of same date, in Solorzano's _De jure Indiarum_ (Madrid, 1629), i, pp. 612, 613. _Inter cætera_ of May 4 is also given in Solorzano, p. 610; _Alguns documentos_, (Lisboa, MDCCCXCII), pp. 65-68; and Calvo's _Recueil complet de traités de l'Amérique latine_ (Paris, 1862), i (premiere période), pp. 1-15, in both Latin and Spanish versions. For the Bull of September 25 we have used the Spanish text, which Navarrete gives _ut supra_, pp. 404-406 (449-451, 2d ed.)--Solorzano's Latin version, which has been followed by Hernaez and other editors, being probably only a retranslation from the Spanish.

Rep_., 1891, pp. 101-130 (republished in _Yale Review_, May, 1892), and in his _Essays in Historical Criticism_ (N. Y., 1901), pp. 193-217; S.E.
