Abstract :
Dear Professor Bell, I am sorry I have not been able to write to you sooner to tell you how very useful I find the Telephones which you so very kindly sent me. I have them fitted up as a means of communication between my house and my laboratory, and between my laboratory and the workshop of Mr White, my instrument maker, in Sauchiehall Street. On the latter circuit I have found them of the greatest service. By their aid I have been able to interrogate Mr White as to the progress of work in his hands, to advise him when difficulties occurred, to give him directions as to points of detail which otherwise might have been passed over, and even to describe fully to him a new instrument, and almost always I found that he had quite understood me. A great deal of time has thus been saved to me which otherwise would have been consumed in travelling between Mr. White??s workshop and the University.
