Sept. 14, 1894. Lewis Glass, Esq., #216 Bush st., San Francisco, Cal., My dear Glass:- I have your letter of Aug. 23rd, and have also received the spring motor for Phonograph, which you kindly sent me. This machine may be alright for exhibition purposes, where it is not possible to obtain electricity to charge storage batteries, or with parties using primary batteries. The future Phonograph, however, will run with a battery, and the new model which I have gotten out, weighs 19 lbs., runs with a half an ampere, or one seventh of the current now employed. We shall furnish this Phonograph equipped with the Edison Lalande Battery, guaranteeing it to run one year for three hours a day with absolute regulation. The intention is that this will be more [illegible overstruck word] for household purposes, so that an evening’s entertainment can be enjoyed, the machine taking the place of a piano or organ. Yours very truly, Thos A. Edison R[andolph]
