This document is a carbon copy of a 61-page typescript. The entries pertain primarily to Edison's life and work during the period 1873-1889. At the top of the first page is an inscription in William H. Meadowcroft's hand: "First Batch," "Notes dictated by Mr. Edison to T. C. Martin June, 1909," and "Pencil indicates Mr. Edison's revision." The scattered corrections and additions in pencil are probably in the hand of T. Commerford Martin. The original typescript and handwritten source text have not been located.
