“There are several residing at present in Dublin who were present at my telephonic experiments in 1865; three of them, namely, Dr. W. Frazer, Mr. A. M. Vereker, and Mr. E. C. Tuke, took an active part in the experiments, and remember all the circumstances connected with them. The voice of each was instantly recognised in the receiver; in fact, this point attracted special attention at the time.
“I had no knowledge at that time that Reis had used an electromagnetic receiver, nor did I know that Reis was the inventor of the instrument which I got from Mr. Ladd.
“The original instrument made by me is, I believe, still in the Museum at Clongowes Wood College. The President kindly lent it to me some time ago, and I returned it to him again after showing it to Professor Barrett. I have a cut of this receiver, which I will send to you if it will be of any use to you.
“Yours truly,
“S. M. Yeates.”
