This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining
the same format as the original work. While some publishers have opted to apply OCR (optical character recognition)
technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters
and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this
work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance
the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or
errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite
these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation
commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of
these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that
intended by the original publisher.
