Title: The mystic thesaurus, or, Initiation in the theoretical and practical secrets of astral truth and occult art
Description: Below is provided the first half of an advertisement for the Mystic Thesaurus as was published in the *Star of the Magi* Newsletter, November 1899. The contents listing is of each "chapter" heading, but many chapters were only a paragraph or two long. The second half of the 1899 advertisement consisted of only testimonials and I'm omitting those here.

Some of the basic information found in this book was initially found in Agrippa's three books that Whitehead translated into English.  Some of the information in the Mystic Thesaurus can be found in Agrippa's *Natural Magic*, but Whitehead expanded and explained this information with more detail and, in some cases, gives some examples to help explain the methods or thoughts to the reader.
