ANTONIO DE LEON Y PINELO. "Tratado de Confirmaciones Reales de Encomiendas, Oficios, y casos en que se requieren para las Indias Occidentales." Madrid, 1630.--This work is one of the best on many vital points of Spanish administration,--and since the latter is so intimately connected with the past and present condition of the aborigines as to make its knowledge absolutely necessary,--it must be attentively studied.--I shall, for this reason, add below the books of Solòrzano: "Epítome de la Biblioteca Oriental i Occidental, Náutica y Geográfica." Madrid, 1629. 2d Edition, by Barcia, 1737 and 1738. (Important bibliographically.) "Relácion que en el Consejo Real de las Indias hizo el Licenciado ..., sobre la Pacificacion de las Provincias del Manché y Lacandon," 1639. MS. of E. G. Squier. JUAN DE SOLÓRZANO-PEREYRA. "Disputationem de Indiarum jure, sive de mixta Indiarum Occidentalium inquisitione, acquisitione, et retentione tribus libris compehensam." (This is the title of the first volume only, the second volume bears the heading "De Indiarum gubernatione, &c.") Madrid, 1629-1639.--2d edition, 1672. "Política Indiana." Madrid, 1648.--Subsequent editions, 1703, 1736-39, 1776. The latter work is but a Spanish transcription or version of the first. The importance of both is in their clear "exposé" of the principles of right and law, according to which the Spanish Indies were governed.--We are thereby enabled to judge of the true relations existing between the conquering and conquered races, and to detect, how far the original condition of the latter was understood or misunderstood by the former--(and misrepresented?) * * * * * The "Museo Nacional," at Guatemala, has the following manuscripts besides those already mentioned: "Historia de la Provincia de Predicadores de San Vicente de Chiapa y Guatemala."--A fragment, possibly by _Fray Augustin Cano_. "Solicitud que el Padre Fray Augustin Cano hizo al Ill'mo S^r Obispo de Guatemala ... que se hallaba de visita en el pueblo de Cajabon pidiendo amparo para reducir á los indios Choles." "Informé dado al Rey por el _Padre Fray Augustin Cano_ sobre la entrada que por la parte de la Verapaz se hizo al Peten en 1695." "Suma de los Capítulos generales y principales, ordenaciones, &c., de la Provincia de Predicadores de Chiapa y Guatemala." by _Fray Lope de Montoya_. "Vidas de varios Padres de la Provincia de Chiapa y Guatemala del Orden de Indicadores," by _Fray Antonio de Molina_. Whether the "Noticia ó Relacion de los Padres de la Orden de Predicadores que florecian en la Provincia de los Zoques" (anonymous MS.), belongs to the 17th century, I am unable to say. * * * * * Notice of the following books or writings has been communicated to me from various sources:
