The author died in 1871, so this work is in the public domain in its country of origin and other countries and areas where the copyright term is the author's life plus 100 years or fewer .
This work is in the public domain in the United States because it was published (or registered with the U.S. Copyright Office ) before January 1, 1929.
This tag is designed for use where there may be a need to assert that any enhancements (eg brightness, contrast, colour-matching, sharpening) are in themselves insufficiently creative to generate a new copyright. It can be used where it is unknown whether any enhancements have been made, as well as when the enhancements are clear but insufficient. For known raw unenhanced scans you can use an appropriate {{PD-old}} tag instead. For usage, see Commons:When to use the PD-scan tag .
