June 4 96 H. Wallerstein Esq- P. O. Box 2737 New York. Dear Sir :- Your favor of the 2nd inst, came duly to hand and in reply I beg to state that I have not patented it because I lost $40,000 on the incandescent Light. I donot propose to lose another $40,000 00. French Patents are not worth a damn – Yours truly Thos. A. Edison R[andolph]
