Volume I: Contains three narratives of voyages to the Pacific, translated and edited. Volume II: Contains two further narratives, translated and edited, including one by Torquemada, and an appendix of letters and memoranda addressed to Philip III.
The supplementary material includes the annual report for 1903.
The main pagination of the two volumes is continuous. This is a new print-on-demand hardback edition of the volumes first published in 1904.
Owing to technical constraints it has not been possible to reproduce the three maps original included in a pocket at the back of the first edition of volume I of the work.
