This undated notebook was probably used sometime between 1894 and 1898. At the beginning of the book are lists and notes by Mina Miller Edison regarding her schedule for a week\'s activities. Included are notes about arrangements, a guest list, and a draft invitation for a party. Among the guests listed are Llewellyn Park residents, such as Henry B. Auchincloss and various members of the Colgate family; Edison associates, such as Charles Batchelor; and several members of the Miller and Edison families, including Mina\'s siblings, Theodore and Grace, and Edison\'s sons, Thomas and William. The remainder of the book contains notes, drawings, and calculations by Edison, probably relating to ore milling, as well as a list noting the properties of numerous organic compounds. The pages are unnumbered, and several pages have been removed from the book. Approximately 80 pages have been used.
