Illustrations have been moved to fall between paragraphs, so the page numbers in the List of Illustration do not always correspond to the positions in this eBook. In versions of this eBook that support hyperlinks, the links lead directly to the correct illustrations.
Footnotes originally began on the same pages as the text that referred to them. In this eBook, the footnotes have been collected together, renumbered sequentially, and moved to just precede the Index.
Index not systematically checked for proper alphabetization, correct page references, or spelling that matched the referenced text. When spelling differences were found between Index entries and the referenced text, the Index was changed to match the text.
Index referenced footnotes by the page numbers on which they appeared. The footnotes have been moved to the end of this eBook, but those references still are to their original pages.
Page [48]: Unmatched opening quotation mark before “the efforts”.
Page 102 ([footnote]): “Abdullāh” was printed that way; all other occurrences in the book were printed as “`Abdullah”.
Page [124]: “Leignitz” was printed that way in the text and the Index.
Page [131]: Date errors. The Christian year “1063” was converted incorrectly: it should be 1073. Later in the same paragraph, the A.H. date “446” is a typographical error for “466”.
Page [193]: The Geneaolgy chart originally appeared on page 190, but was moved to the end of the chapter so that it would not interrupt the flow of the narrative. Consequently, all Index references to page 190 will be found at the [bottom] of page 193 (the links have been adjusted to do this).
