BERNARDO LIZANA. (Lizama or Lizaba?) "Devocionario de Nuestra Señora de Itzmal, Historia de Yucatan é de conquista Espiritual," 1663, according to the Abbé Brasseur and Leon y Pinelo.--E. G. Squier speaks of two works: one "Historia de la Provincia de Yucatan, y su conquista Espiritual," Valladolid, 1633, and the other "Historia de Nuestra Señora de Izamal."--Whichever way may be right, there remains accessible as yet, but a fragment published in Spanish, with a French translation by the Abbé Brasseur in his "Relation des choses de Yucatan," 1864. The fragment is entitled: "Del principio y Fundacion destos cuyos omules deste Sitio y Pueblo de Ytzmal...."--Lizana is of the highest importance and value, and it is much to be regretted that the _entire_ book is of such difficult access. DIEGO LOPEZ DE COGOLLUDO. "Historia de Yucatan."--1st Edition, Madrid, 1688; 2d Edition, Mérida, 1842; 3d Edition, 1867.--Cogolludo has always been regarded as the historian of Yucatan "par excellence." He is indeed indispensable for any study of Yucatan antiquities, but, like all other authors, he must never be implicitly followed. The closest criticism possible is absolutely required. GIL GONZALEZ DÁVILA. "Teatro ecclesiástico de la primitiva Iglesia de los Indios Occidentales." Madrid, 1649. JUAN DIAZ DE LA CALLE. "Memorial y Resûmen breve de Noticias de las Indias Occidentales." Madrid, 1654. * * * * * These constitute the most important sources on Yucatan written during the 17th century. Nearly all of them are of _special_ value, and we would call particular attention to Cogolludo, Lizana, Torquemada, Herrera, and Remesal. Among such authors, who wrote upon the subject and whose writings are not now accessible, I name here: PEDRO SANCHEZ AGUILAR. "Relacion de las Cosas de Yucatan, y Informe contra los Idólatras del Obispado de Yucatan, &c." 1639. FRANCISCO CÁRDENAS. "Relacion de la Conquista y Succesos de Yucatan," 1639. (If existing, probably in Spain). NICOLÁS LIZARRAGA. "Representacion al Rey pidiéndole la Conquista de Itzá y Lacandon, con unas Noticias y Mapa de dichas Tierras." NICOLÁS DE VALENZUELA. An account of the expedition against the Lacandones, written 1695, and comprising 402 pages. I would further call attention to the land titles, such as Deeds, Grants, donations, &c., &c., in Yucatan, some of which go back to the 17th century. These contain occasional references to the Indian settlements, some of which are certainly of great value and importance. Finally, I refer to some general works, treating of Yucatan: SAMUEL PURCHAS. "His Pilgrimage, &c., &c." London, 1613, 1614 and 1617. (This forms the 5th volume of Purchas' great works).--The great work of Purchas, also known as "Hackluytus Posthumous," appeared in 1625, and treats also of Yucatan. O. DAPPER. "Die unbekannte neue Welt, oder Beschreibung des Welt-theils Amerikas, &c." Amsterdam, 1673. This is in fact but a translation of the following:
