Wireless Telephony Lecture

Professor E. L. Chaffee will talk before the New England Wireless Association on his new method of wireless telephony in the Lecture Room of Jefferson Physical Laboratory this evening at 8 o'clock. Professor Chaffee and Professor G. W. Pierce have been working on this invention for some time, and with considerable success.

This system uses an are instead of the customary spark for transmitting the sound, the are being formed between aluminum and copper electrodes in pure hydrogen. With this method Professors Chaffee and Pierce have been able to send to Gloucester, a distance of 35 miles, and hope to do even better in the near future.
