Punctuation, hyphenation, and spelling were made consistent when a predominant preference was found in this book; otherwise they were not changed.

Simple typographical errors were corrected; occasional unbalanced quotation marks retained.

To make this eBook easier to read, particularly on handheld devices, most images have been made relatively larger than in the original pamphlet, and centered, rather than offset to one side or the other; and some were placed a little earlier or later than in the original. Sidebars in the original have been repositioned between chapters and identified as “[Sidebar (page nn):”, where the page reference is to the original location in the source book. In the Plain Text version, the matching closing right bracket follows the last line of the Sidebar’s text and is on a separate line to make it more noticeable. In the HTML versions, that bracket follows the colon, and each Sidebar is displayed within a box.

Page 27: “Consolidated” was printed as “Condolidated”; changed here.

Page 40: “Corrigedor” was printed that way.
