April 9th 1890 Master Josef Hofmann, Berlin, Germany Dear Master Hoffman:- Mr. Edison has asked me to acknowledge the receipt of your letter of 22nd ultimo, which was perused by him with much pleasure, and he desires me to thank you for the photograph of yourself, which you kindly enclosed. He would be very pleased to receive a musical record made by yourself. In sending this, please pack it very carefully, so that it will sustain no injury in transportation. With reference to the "one thing," which you do not understand this little device in the determining point. When the lever on the back of the Phonograph is pulled down, this point strikes the cylinder, and adjusts the knife for cutting. If the point in question were not there, the knife would dig into the cylinder, and would take so deep a chip to spoil it. This point regulates the depth of the chip, making it always uniform. I hope the above explanation will make clear to you, the use of the determining point. If there is anything else about the Phonograph that you do not understand, and which you would like to have explained, if you will write us about it, we will be very pleased to furnish you with all the information possible. I am sending you by this mail, under another cover, a photograph of Mr. Edison, which he has dedicated to yourself. Very truly yours, A.O. Tate Private Secretary
