[Footnote 11:  The centuries, hundreds, thousands, etc., appear to represent multiples of twelve, not ten.—­ED.]

[Footnote 12:  Aluminium?—­ED.]

[Footnote 13:  Here, and here only, the name is written in full; but the first part is blurred.  It may be Alius (Ali), Julius (Jules), Elias, or may represent any one of a dozen English surnames.  The single cipher, employed elsewhere throws no light on it.—­ED.]

[Transcriber’s Notes:  A page was torn in our print copy, causing a few lines in Chapter I to be illegible.  The missing words have been indicated with [***].  Also, “authypnotism” was corrected to “autohypnotism.”]
