Wyatt's book, in turn, had taken much material from "The Conchologist's Textbook" by the British naturalist Thomas Brown without attribution. Brown's book had been published in Glasgow, Scotland in 1837. Brown had based his text on the previous work of Jean-Baptiste Lamarck and Carl Linnaeus, noting on the title page that his book was "embracing the arrangements of Jean-Baptiste Lamarck and Linnaeus". Poe had penciled in as the last sentence to the preface of his personal copy of the first edition an acknowledgment to Brown: "Also to Mr. T. Brown upon whose excelent book he has very largely drawn". However, this acknowledgement was not incorporated into the second edition.
