February 18, 1891. Messrs. Dyer & Seely, #36 Wall Street, New York City. Dear Sirs:- With reference to your letter of 12th instant regarding note books in which were recorded the experiments made by Mr. Edison prior to his application for patent on Motor-Meter (Patent No. 242,901), I have consulted Mr. Jno. Ott on this subject, and he has made a search for the note books but is unable to find them at the Laboratory. He says that "there are some very good curves contained in the note books referred to, showing the meter being constant, and quite proportionate to load." Mr. Ott says further that these experiments were conducted about the year 1883 or 1884, at 17th Street, New York, and he is of the opinion that parts of the model must be in the Laboratory now. Mr. Force and Mr. Hamilton assisted in the experiments. Mr. Ott says that the note books must be in the Vault in New York. Yours truly, Private Secretary.
