Another scholar, to whose literary stores I am largely indebted, is Don Martin Fernandez de Navarrette, late Director of the Royal Academy of History. Through the greater part of his long life he was employed in assembling original documents to illustrate the colonial annals. Many of these have been incorporated in his great work, "Coleccion de los Viages y Descubrimientos," which, although far from being completed after the original plan of its author, is of inestimable service to the historian. In following down the track of discovery, Navarrete turned aside from the conquests of Mexico and Peru, to exhibit the voyages of his countrymen in the Indian seas. His manuscripts, relating to the two former countries, he courteously allowed to be copied for me. Some of them have since appeared in print, under the auspices of his learned coadjutors, Salva and Baranda, associated with him in the Academy; but the documents placed in my hands form a most important contribution to my materials for the present history. The death of this illustrious man, which occurred some time after the present work was begun, has left a void in his country not easy to be filled; for he was zealously devoted to letters, and few have done more to extend the knowledge of her colonial history. Far from an exclusive solicitude for his own literary projects, he was ever ready to extend his sympathy and assistance to those of others. His reputation as a scholar was enhanced by the higher qualities which he possessed as a man,--by his benevolence, his simplicity of manners, and unsullied moral worth. My own obligations to him are large; for from the publication of my first historical work, down to the last week of his life, I have constantly received proofs from him of his hearty and most efficient interest in the prosecution of my historical labors; and I now the more willingly pay this well-merited tribute to his deserts, that it must be exempt from all suspicion of flattery. In the list of those to whom I have been indebted for materials, I must, also, include the name of M. Ternaux-Compans, so well known by his faithful and elegant French versions of the Munoz manuscripts; and that of my friend Don Pascual de Gayangos, who, under the modest dress of translation, has furnished a most acute and learned commentary on Spanish Arabian history,--securing for himself the foremost rank in that difficult department of letters, which has been illumined by the labors of a Masdeu, a Casiri, and a Conde.
