ANTONIO DEL RIO. "Descripcion del terreno y poblacion antigua nuevamente descubierta en las inmediaciones del pueblo del Palenque."--I have already referred to it under "Yucatan." Whether the plates of the English edition are genuine, is yet doubtful. * * * * * I must add here, that until about 1820, the state of Chiapas pertained, not to Mexico, but to the captain-generalcy of Guatemala, and consequently all the authorities treating of the latter country may be supposed to contain information about Chiapas also. _Writers of the Nineteenth Century._ (Explorations of Palenque.) JUAN GARRIDO. _Said_ to have written about Palenque in 1805. GUILLERMO DUPAIX AND LUCIANO CASTAÑEDA. "Relacion hecha al Rey, sobre tres expediciones, &c." in 1805, 1806, and 1807. They visited Palenque late in 1807.--Their reports and drawings were first published in 1831, in Vols. IV. and V. of Lord Kingsborough's "Antiquities of Mexico," and an English translation in Vol. VI.--A French and Spanish version, together with all the plates, is contained in "Antiquités mexicaines." Paris, 1834.--The drawings of Castañeda are by far the most complete which we have, although they disagree with many of those of other travellers. This disagreement will be referred to hereafter. JUAN GALINDO. "Palenque et autres lieux circonvoisins." Letter dated 27 April, 1831, in "Antiquités méxicaines," Vol. I.--English translation in the "Literary Gazette," No. 769, London, 1831.--Col. Galindo visited Palenque himself, but he is so enthusiastic that all his statements and even measurements should be taken with many allowances. FRIEDRICH VON WALDECK. "Description des ruines de Palenque," with 56 large plates, in "Monuments anciens du Méxique." Paris, 1866.--M. de Waldeck had spent two years at Palenque (1832-1834,)--his plates are magnificent, but they restore far too much. JOHN L. STEPHENS. "Travels in Central America, Chiapas, and Yucatan." N. York, 1841. "Incidents of Travel in Yucatan." 1843. F. CATHERWOOD. (See Yucatan.) ARTHUR MORELET. (See Yucatan.) Visited P. in 1846. DÉSIRÉ CHARNAY. (See Yucatan.) In 1858. CHARLES ETIENNE BRASSEUR DE BOURBOURG. "Ruines de Palenque," in "Monuments anciens du Méxique," 1866, Paris.--Valuable for the historical introductions and for the numerous references to authorities. The historical essay is a confused and disorderly jumble, barely readable.--The Abbé visited Palenque subsequently--in 1871. To these reports I finally add: CHARLES RAU. "The Palenque tablet in the United States National Museum," Washington, D. C., 1879. (No. 331 of "Smithsonian Contributions to Knowledge.") * * * * *
