About the Numbers: The numbers accom-panying the images are published for the first time in this book. They were stamped on the side of each engraving as an indexing system. The notation following the index number, added for this project, tells more about each engraving. The Key to the notation is found on the following pages.

These are the front and back pages of the "Y" section. Each section of the book has 16 pages in it. You might notice the "Y" to the left of the printed page # 369 on the bottom of the right page. These are markings for the binder for collating the book correctly. This was a common practice for books in the 19th century and earlier. In modern books these marks are printed on the folded spine edge of the folios. Thus, they are hidden by the binding. The letters on the right side of the page are a design element taken from the International Dictionaries - they are used for the thumb-tab indexing system. The proofs of the pages with a complete set of 13 letters on the edge are from the regular edition which will not have indexes cut into the pages, and the proofs with missing letters such as the one above are from the deluxe edition. The letters must be left out to insure the indexing punches don't punch partially through letters.
