Note 11 — Chapter XV · THE MYSTERIOUS CHAMBER.
Daniel De Leon translation
"The use of tanned skins for writing dates back to remote antiquity, and was common among the people of Asia, as well as among the Greeks, Romans and Gauls. At the Library at Brussels is a manuscript of the Pentateuch which is thought to antedate the Ninth Century B. C. It is written on fifty-seven skins sewed together, making a roll of about forty yards in length."—Ludovic Lalaune, Curiosities of Bibliography, p. 11.
