Abstract
IT may be of interest to state that the Marconi Co.'s demonstration at Chelmsford of wireless telephony on May 28, alluded to in NATURE for June 5, was clearly heard on wireless apparatus in this house. Every word could be clearly recognised, the speaking being most distinct and very loud. What was heard included the reading of several newspaper paragraphs, the playing of gramophone records, and some remarks by Mr. Godfrey Isaacs, in which he said that no one would be able to overhear the conversation, as it required very special apparatus to pick it up!
