Transcriber’s Note:

Obvious mis-spellings and printing errors have been corrected and noted by the use of a faint grey dotted line.

Missing periods at paragraph-end have silently been supplied. Inconsistencies in hyphenation and accentuation have been retained.

The romanization of Arabic is the author’s.

The cover image has been digitally edited to repair damages and to restore colors; the author and title was superimposed for the reader’s convenience.
