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 projectto 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 subjectto copyright or whose legal copyright term has expired. Whether a book is in the public domain may vary country to country. Public domain booksare 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 of this book’s long journey from thepublisher to a library and finally to you.
Usage guidelines
Google is proud to partner with libraries to digitize public domain materials and make them widely accessible. Public domain books belong to thepublic and we are merely their custodians.
