About this book

This is a digital copy of a work that has been preserved for generations on library shelves before being carefully scanned by Google as part of a project aimed at allowing internet users to discover the entirety of the world's literary heritage online.

Since this book is relatively old, it is no longer protected by copyright law and now belongs to the public domain. The expression "belonging to the public domain" means that the book in question has never been subject to copyright or that its legal rights have expired. The requirements for a book to fall into the public domain vary from one country to another. Public domain books are so many links to the past. They are witnesses to the richness of our history, our cultural heritage, and human knowledge, and are all too often difficult for the public to access.

The footnotes and other annotations in the margins of the text present in the original volume are included in this file, as a memory of the long journey traveled by the work from the publishing house, through the library, to finally find itself in your hands.

Usage guidelines

Google is proud to work in partnership with libraries to digitize works belonging to the public domain and thus make them accessible to everyone. These books are indeed the property of all, and we are simply the guardians of this heritage. However, this is an expensive project. Consequently, and with a view to continuing the dissemination of these inexhaustible resources, we have taken the necessary steps to prevent potential abuses by third-party commercial sites, notably by establishing technical constraints regarding automated queries.

We also ask you to:

• Do not use the files for commercial purposes We designed the Google Book Search program for use by individuals. We therefore ask you to use these files only for personal purposes. They cannot, in fact, be employed for any commercial goal whatsoever.

• Do not perform automated queries Do not send any automated queries of any kind to the Google system. If you are conducting research concerning translation software, optical character recognition OCR, or any other field requiring large quantities of text, please do not hesitate to contact us. For the realization of this type of work, we encourage the use of works and documents belonging to the public domain and would be happy to be of assistance.

• Do not remove the attribution The Google watermark contained in each file is essential for informing internet users of our project and allowing them to access more documents through the Google Book Search Program. Do not remove it under any circumstances.

• Stay within the law Whatever use you plan to make of the files, remember that it is your responsibility to ensure you respect the law. If a work belongs to the American public domain, do not assume that the same applies in other countries. The legal duration of a book's copyright varies from one country to another. We are therefore not in a position to list which works are authorized for use and which are not. Do not believe that the simple fact of displaying a book on Google Book Search means that it can be used in any way whatsoever throughout the entire world. The penalties to which you might be exposed in the event of copyright violation can be severe.
