Title
[LB018398], Letter from Thomas Alva Edison to H Mordecai, September 23rd, 1884
Editor's Notes
Referring to your favor of the 13th. inst., I beg to state that the Pennsylvania R.R. have already tried the electric ball, such as I imagine you would suggest. With what success, however, I do not know. I believe they are now trying some arrangement in which compressed air is the force used.
