[NM022AAE], Technical Note, Thomas Alva Edison, January 17th, 1888

Editor's Notes

For this purpose I have discovered that Carnauba Wax is the best hardener for mixing with the various soft waxes, and it may be used in various proportions up to the point where it is such quantity as to cause [excess? C-------] scraping sounds." [probably in interference with earlier Tainter appn]
