The one dated entry in this notebook is from December 1894. The first page bears the inscription: "Mr. J. Coote Edisons Laboratory Orange, N.J. Dec 11th 94." All remaining entries are by Edison and pertain to squirted filament experiments, with notations for boxes numbered 1-20 and brass boxes numbered 1-8. Near the end of the book is a page entitled "Index," which has no apparent relation to the preceding entries. The front cover is labeled "Various Experiments By Mr J Coote." The pages are unnumbered, and several pages have been removed from the book. Approximately 35 pages have been used. Two loose pages of calculations have been inserted into the book.
