There are also experiments on wax master blanks with varying ingredients. Many of the phonograph entries include notations by Hayes regarding Edison's instructions, comments, or opinions. Numerous items, including some with notations by Edison, have been affixed onto or between the notebook pages. In addition, several loose items from 1922 (by Hayes) and 1925-1926 (by F. C. Burt) have been inserted into the book. The book contains 4 unnumbered pages, followed by 127 numbered pages (some blank), and 23 additional unnumbered pages.
