It's written in the Freemason's cipher, which any schoolboy knows. 

; Antiquarian
: ''Bibliotheca Sussexiana''  is a descriptive catalogue of the Duke of Sussex's vast library, but it covers only the Theology works in 2 volumes and 3 parts. Volume 1, parts 1 & 2, is Manuscripts. Volume 2 is Bibles.
; Art (Calligraphy)
: It's written in a masculine hand of the Regency period, even though it's more like block capitals.
; Bibliography
: Thomas Pettigrew served as librarian to the Duke of Sussex from 1818 to 1845. His three-volume catalogue of His Grace’s collection, the Bibliotheca Sussexiana, covers only a portion of the whole, mostly theological and religious works from all over the world.
; Bibliography (Malcolm Collins)
: The extensive and valuable library of the late Duke of Sussex was sold at auction by Messrs Evans; in 1844 on the 1st and 31st July, 12 August; in 1845 on 30 January, 22 April, 11 August. The two biggest buyers were Sir Thomas Phillipps and the British Museum.
: You've seen the complete set of the sale catalogues of the Bibliotheca Sussexiana, the only complete record of the Duke's vast library, come up for auction themselves. There are people who collect sale catalogues.
: Franklin Dunhill's bibliophile grandfather, who collected the library you were trying to get access to last night, was collecting in the 1840s. There should be a set of Bibliotheca Sussexiana sale catalogues in Dunhill's library.
; Chemistry
:The paint on the reverse of the last sheet is a typically Victorian period linseed oil based paint. It shouldn't be difficult to replicate.
; Craft (Papermaking)
: It's Regency period paper. It'll be laid rag paper. Watermarked, no doubt.
; Cryptography
: You can read it straight off the page because it's the pigpen cipher, also called the masonic cipher, Freemason's cipher, or Rosicrucian cipher. It purports to be Volume 3, Occult.
; Document Analysis
: You can date the paper and ribbon to before 1854. The paper was from Her Majesty's Stationery Office, James Street, Buckingham Gate.
; Occult
: Besides many occult works that you are familiar with, the catalogue contains some interesting works that you are unfamiliar with. The most recent is
:: Charles Leggett, ''Mysteries of the Worm'', London 1821. An English translation of the German black-letter translation of the Latin ''De Vermis Mysteriis''.
: The most interesting is
:: Anon., ''Cultus Maleficarum (The Sussex Manuscript)'', Sussex 1598. Dedicated to Baron Frederic of Sussex, an English translation of the Latin translation by Olaus Wormius of the Greek ''Necronomicon''. Not a manuscript, but a printed book that resembles an illuminated manuscript.
; Textual Analysis (Sebastian Crowe)
: What you can decipher in your head matches Thomas Pettigrew's style. This seems to be an unknown volume of the ''Bibliotheca Sussexiana''.
; Textual Analysis (Frances Bradley)
: It was written in the 1820s, it's a descriptive catalogue, and the style matches the ''Bibliotheca Sussexiana'' closely.
