(7.) Herr Peter, a former colleague of Philipp Reis, whose testimony will be found on page 126, narrates how he doubted the powers of the instrument until he had verified them for himself by speaking into it words which could not possibly be premeditated. (8.) Mr. E. Horkheimer, who aided Reis in his earlier work, though he left Germany when the development of the instrument was yet very far from complete, has even given (see p. 117) a list of the words and expressions which he has heard transmitted by the earlier forms of the instrument. (9.) Herr Philipp Schmidt, brother-in-law of Philipp Reis, and now acting-paymaster in the Imperial German Navy at Wilhelmshavn, says: “he succeeded finally in reproducing at a distance, words and whole sentences.” “There never was any understanding between my brother-in-law and myself as to particular words and sentences: on the contrary, these were quite spontaneous.” (10.) Mr. S. M. Yeates, of Dublin, who in 1865 constructed a modified Reis Telephone (see p. 128), has thus described the performance of the instrument: “Before disposing of the apparatus, I showed it at the November meeting (1865) of the Dublin Philosophical Society, when both singing _and the distinct articulation of several words were heard through it, and the difference between the speakers’ voices clearly recognised_.”[13] It is difficult to conceive how testimony on this point could be stronger. From so many different sources it is alike agreed that--with the instrument presumably in good adjustment--_Reis’s Telephone_, in the hands of Reis and his contemporaries, _did transmit articulate speech_. III.--Reis’s Telephone will transmit speech.
