Helps Telephone Talk.

What is hailed as a great improvement in telephony is an improved transmitter which has been recently devised by a French physician and which was recently described by Prof, before the French Academy of Sciences. The inventor is Dr. Jules Glover, and is based on his observation that many of the sounds escaping from the larynx are divided in the throat and a large portion of them are emitted through the nose. With the type of receiver now made use of these are lost, but he has designed a receiver with two diaphragms, one much more sensitive than the other, and the nasal sounds are transmitted through this auxiliary diaphragm. This improvement is said to completely remove some of the difficulties to conversation which have hitherto existed, and makes it possible to carry on conversation over longer distances than heretofore.
