The new edition sold out within two months and was used in schools as had been hoped, though Poe received no royalties for its sales. The edition was the cause of several accusations of
plagiarism against Poe. In 1844, Poe tried to publish more of his work with Harper's (which had also printed his novel
The Narrative of Arthur Gordon Pym of Nantucket) but was informed by a friend, "They have
complaints against you... grounded on certain movements of yours." Poe denied the charges and wrote that he would sue over the allegation: "This charge is infamous, and I shall prosecute for it, as soon as I settle my accounts with the 'Mirror.'" As he explained the book: I wrote it in conjunction with Professor Thomas Wyatt, and Professor McMultrie... my name being put to the work, as best known and most likely to aid its circulation. I wrote the Preface and Introduction, and translated from Cuvier, the accounts of the animals, etc.
All School-books are necessarily made in a similar way. A second edition appeared in 1840 with Poe's name on the title page, but the 1845 edition appeared without it. 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 [sic] book he has very largely drawn". However, this acknowledgement was not incorporated into the second edition. ==Significance==
