Aside from the numberless historical, archæological, and ethnological works, several of which I have already noticed under "Yucatan," I beg to refer to some specifically Central-American and Mexican sources treating of Chiapas in general, with some occasional mention of Palenque and of Ocosingo, or even without any particular reference to them. DOMINGO JUARROS. "Compendio de la Historia de Guatemala," 1808--1818.--English translation by J. Bailly, London, 1823. FRANCISCO DE PAULA GARCIA L'ELAEZ. "Memorias para la Historia del antiguo Reyno de Guatemala." 3 vols. Guatemala, 1851.--An excellent work, full of valuable and reliable information. HYACINTHE DE CHARENCY. "Le Mythe de Votan." Alençon, 1871.--Ingenious speculations. FÉLIX CABRERA. "Teatro crítico-americano."--Published with the different editions of Del Rio.--Abstract from Nuñez de la Vega, with more or less hypothetical speculations about the origin, life, and doings of "Votan" in Chiapas. MARIANO ROBLES DOMINGUEZ DE MAZARIEGOS. "Memoria histórica de la provincia de Chiapas...." Cadiz, 1813. EMILIO PINEDA. "Descripcion Geógráfica del Departamento de Chiapas y Soconusco." In the "Boletin de la Sociedad de geografia y Estadística de México." Vol. III. Also, México, 1845. JOSÉ DE GARAY. "Reconocimiento del Istmo de Tehuantepec." México, 1844. FRANCISCO PIMENTEL. "Cuadro descriptivo de las Lenguas indígenas, &c." (See Yucatan.) MANUEL OROZCO Y BERRA. "Geografia de las Lenguas." (See Yucatan.) * * * * * In the imperfect list herewith submitted I have frequently included works of which nothing is known save that they once existed. This is done for the purpose of calling attention to them, should any one of them be found in the hands of book owners and collectors here or abroad. Libraries like those of Mr. Lenox or of Mr. John Carter-Brown should be searched for such writings, and copies at least should be secured. The plan of Palenque, made by Bernasconi, in 1785, should also be copied without delay. A copy can be obtained from Madrid, by application to the Royal Academy of Spain. GUATEMALA. (Copan and Chiapas included.) _Writers of the Sixteenth Century._ HERNAN CORTÉS. (4th and 5th letter. Casual mention.) PEDRO DE ALVARADO. Seventeen letters to Hernan Cortés, the first of which is dated: Utlatlan, 11 April, 1524. Only two of those letters were printed, the remaining fifteen are yet in MSS. Mr. E. G. Squier owned MS. copies of the whole, but whither they went at his sale I do not know. The two which were published (11 April and 28 July), appeared in the following works: "Delle navigationi et viaggi, &c." by Gian Battista Ramusio. Venice, Italian version. The "due lettere de Pietro d' Alvarado," are contained in the 3d volume, editions of 1556, 1565, and 1606. OVIEDÓ. "Historia y natural de las Indias." Vol. III. Written between 1535 and 1557, but printed only 1853. Madrid.
