Many of the best materials for the state of culture in Spain, during the reign of Charles III., are to be found in the “Biblioteca de los Mejores Escritores del Reynado de Carlos III., por Juan Sempere y Guarinos,” Madrid, 1785-89, 6 tom. 8vo. When the author published it, he was about thirty-five years old, having been born in 1754; but he was afterwards much more distinguished as a political writer, by his “Observaciones sobre las Cortes,” (1810,) his “Historia de las Cortes,” (1815,) and other labors of the same kind. His first acknowledged work was a free translation, from Muratori, of an essay, with additions, which he printed at Madrid, in 1782, in 12mo, with the title, “Sobre el Buen Gusto,” and which he accompanied by an original tract, “Sobre el Buen Gusto actual de los Españoles en la Literatura,”--the last being afterwards prefixed, with alterations, to his “Biblioteca.” He was a diligent and useful writer, and died, I believe, in 1824. A small volume, containing notices of his life to the time when it appeared, probably derived from materials furnished by himself, was printed at Madrid, by Amarita, in 1821, 12mo. Under these circumstances, the accession of a prince like Charles the Third was eminently fortunate for the country. He was a man of energy and discernment, a Spaniard by birth and character, but one whom political connections had placed early on the throne of Naples, where, during a reign of twenty-four years, he had done much to restore the dignity of a decayed monarchy, and had learned much of the condition of Europe outside of the Pyrenees. When, therefore, the death of his half-brother called him to the throne of Spain, he came with a kind and degree of experience in affairs which fitted him well for his duties in the more important and more unfortunate kingdom, whose destinies he was to control for above a quarter of a century. Happily, he seems to have comprehended his position from the first, and to have understood that he was called to a great work of reform and regeneration, where his chief contest was to be with ecclesiastical abuses.
