“M. Pignut mentions an instance where, in a public library but little frequented, twenty-seven folio volumes were perforated in a straight line by the same insect [a bookworm], in such a manner that, on passing a cord through the perfectly round hole made by it, these twenty-seven volumes could be raised at once.”
