Four out of these seven books are in the British Museum—the Vocabulario and Arte of Ruiz de Montoya, Yapuguai's Catechism, and the letter of Antequera y Castro. The first two were presented in 1818 by Mr. George Bellas Greenough, the founder of the Geological Society. The Catechism was purchased in 1889, and the letter in 1893. The latter is the only copy hitherto known, and is the only one of the seven books of which some portion is not facsimiled by Señor Medina.
Printing had died out in Paraguay before its introduction into any other portion of the great La Plata region. It revived under Jesuit auspices at Cordova, where towards the end of the seventeenth century a college had been founded by Duarte y Quiros, which had become the chief educational institution of the country. By 1765 it had attained sufficient consequence to become sensible of the inconvenience of being unable to print its theses and other academical documents, which, so wretched was the provision then made for the intellectual needs of the Spanish colonies, could only be done at Lima, more than a thousand miles off on the other side of the Andes. The Viceroy of Peru was accordingly appealed to, and permission obtained, fenced with all imaginable precautions and restrictions. No time was lost in printing five panegyrical orations upon the pious founder Duarte y Quiros, probably by Father Peramas, which appeared in 1766. Two, or possibly three, minor publications, now entirely lost, had followed, when the existence of the press was abruptly terminated by the suppression of the Jesuits, and Cordova never saw another until after the independence. The types, however, not tin like the Paraguayan, but imported from Spain and cast _secundum artem_, were preserved in the college, and in 1780 were transferred to Buenos Ayres, where it had been resolved to introduce typography; not for its own sake, but as a means of raising money towards the support of a foundling hospital, endowed with the proceeds of the printing-press. Official and ecclesiastical patronage were not wanting; by the end of 1781 twenty-seven publications of various descriptions, mostly of course on a very small scale, had issued from the Buenos Ayres press. The first of any kind was a proclamation relating to the militia, facsimiled by Señor Medina; the first deserving the character of a book was, as in British North America, an almanac. The most interesting from their subject were pastoral letters by two bishops on the overthrow of the rebel cacique Tupac Amaru in Peru. The press continued to thrive, and in 1789 it was necessary to procure a new fount of type from Spain. The total number of publications known to the end of 1810 is 851—a very large proportion of which, however, are merely fly-sheets. Some, nevertheless, are of exceptional interest, such as the translation of Dodsley's "Economy of Human Life," perhaps the first translation of an English book ever published in Spanish America, and the numerous broadsides attesting the impression at first produced in the colonies by Napoleon's invasion of the mother country. Eight proclamations by General Beresford during the brief occupation of the city by the British forces in 1806 are of especial interest to Englishmen. In one Beresford endeavours to conciliate the good-will of the inhabitants by promising deliverance from the financial oppression of the Spanish colonial system. They soon afterwards took the matter into their own hands: the publications for the last months over which Señor Medina's labours extend are chiefly proclamations by the Junta and similar revolutionary documents. Among them, duly facsimiled by Señor Medina, is the proclamation of the Junta, with the date of May 23, 1810, announcing the virtual deposition of the Viceroy, the first document of Buenos Ayrean independence, although the authority of Ferdinand the Seventh is still acknowledged in name, and the autonomy of the country was not proclaimed until 1816. Another curiosity, also facsimiled, is a proclamation in Spanish and Quichua, "from the most persecuted American," Iturri Patiño, to the inhabitants of Cochabamba in Upper Peru, more than a thousand miles from Buenos Ayres, exhorting them to welcome their deliverers. The interest is greatly enhanced by Señor Medina's industry in tracing out other works of the writers, published in other parts of South America.
