It is of interest, moreover, to note that the matter did not immediately drop. Professor Böttger, who as one of the regular lecturers of the Physical Society, held fortnightly discourses on matters of scientific novelty, took occasion on the 7th of December to recur to the subject then attracting so much attention. The title of his discourse (see ‘Proceedings’ of the Society, p. 11) was “Application of an Experiment relating to the Transmission of Musical Tones to any desired distance by means of the Galvanic Current.” It is not quite certain whether Reis was present on this occasion. Early in the spring of 1863, appeared in Böttger’s ‘Polytechnisches Notizblatt’ (No. 6 of that year) an article which contains in condensed form Böttger’s discourse. This article was copied into Dingler’s ‘Polytechnisches Journal’ for May 1863. vol. clxviii. p. 185, and also into the ‘Polytechnisches Centralblatt’ for July 1863, vol. xxix. p. 858. An extract of Reis’s own paper, condensed from the ‘Jahresbericht’ by Dr. Roeber (now President of the Physical Society of Berlin), appeared in the ‘Berliner Berichte’ (_i. e._ the ‘Fortschritte der Physik’) for 1861, vol. xvii. pp. 171-173. It is interesting to note that Reis’s paper was then deemed worthy to stand in the pages of the ‘Fortschritte’ by the side of the classic researches of Thomson on Regelation, and of Maxwell on Magnetic Lines of Force. The following is a translation of Böttger’s notice mentioned above.] [=2.=] ON THE TRANSMISSION OF TONES TO A DISTANCE AS FAR AS DESIRED, BY THE HELP OF ELECTRICITY (TELEPHONY). [Translated from the original notice by Professor Böttger, which appeared in Böttger’s ‘Polytechnischen Notizblatt,’ 1863, No. 6, p. 81, in Dingler’s ‘Polytechnisches Journal,’ 1863, vol. clxviii. p. 185, and in the ‘Polytechnisches Centralblatt,’ 1863, t. xxix. p. 858.] Two decades ago we had not yet gone beyond the first attempts to give signals at a great distance by the aid of electricity. Since then telegraphy has attained such a completeness, and the telegraph wire has reached such a universal extension, that there seems little left for even the boldest wish to desire.
