This is a digital copy of a book that was preserved for generations on library shelves before it was carefully scanned by Google as part of a project to make the world’s books discoverable online.
It has survived long enough for the copyright to expire and the book to enter the public domain. A public domain book is one that was never subjcct to copyright or whose legal copyright term has expired. Whether a book is in the public domain may vary country to country. Public domain books arc our gateways to the past, representing a wealth of history, culture and knowledge that’s often difficult to discover.
Marks, notations and other marginalia present in the original volume will appear in this file a reminder t։f this book’s long journey from the publisher to a library and finally to you.
