About this book

This is a digital copy of a book that has been kept on library shelves for generations before being carefully scanned by Google as part of a project to make the world's books available online.
The book has outlived copyright and can now be made publicly accessible. A publicly accessible book is a book that was never subject to copyright or for which the term of copyright protection has expired. Whether a book is publicly accessible may vary from country to country. Publicly accessible books are our gateway to the past and represent a historical, cultural, and scientific asset that is often difficult to discover.
Traces of use, annotations, and other marginalia contained in the original volume are also found in this file—a reminder of the long journey the book has taken from the publisher to a library and on to you.

Usage guidelines

Google is proud to partner with libraries to digitize publicly accessible material and make it available to a wide audience. Publicly accessible books belong to the public, and we are merely their custodians. Nevertheless, this work is costly. In order to continue to provide this resource, we have taken steps to prevent abuse by commercial parties. These include technical restrictions on automated queries.
We ask you to observe the following guidelines:

• Use of files for non-commercial purposes We have designed Google Book Search for end users and would like you to use these files only for personal, non-commercial purposes.

• No automated queries Do not send automated queries of any kind to the Google system. If you are conducting research on machine translation, optical character recognition, or other areas where access to large amounts of text is useful, please contact us. We encourage the use of publicly accessible material for these purposes and may be able to help you.

• Retention of Google brand elements The Google "watermark" that you find in every file is important for informing users about this project and helps them find further material via Google Book Search. Please do not remove the watermark.

• Stay within the law Regardless of your intended use, you must be aware of your responsibility to ensure that your use is legal. Do not assume that a book that we believe is publicly accessible for users in the USA is also publicly accessible for users in other countries. Whether a book is still subject to copyright varies from country to country. We cannot provide advice on whether a specific use of a specific book is legally permitted. Do not assume that the appearance of a book in Google Book Search means that it can be used in any form anywhere in the world. Copyright infringement can have serious consequences.
