In the presence of Sir William Thomson, experiments were made between neighboring rooms in the Equitable Buildings at Boston over a circuit extending to New York and back. The condition of the line rendered the experiment unsatisfactory, but on short circuiting the New York loop the articulation became audible. After the conclusion of the experiment Bell presented the instruments to Sir William Thomson as a memento of the occasion, and they were exhibited by him to the members of the British Association at Glasgow. – John E. Kingsbury 1915
