(Tagesblatt), issued daily, the following notice.] [=13.=] EXTRACT FROM THE REPORT OF THE GERMAN NATURALISTS’ SOCIETY, HELD AT GIESSEN (1864). “Afternoon sitting on 21st September, 1864. “Prof. Buff speaks about the tones of iron and steel rods when magnetised, and exhibits the corresponding experiments. “Dr. Reis demonstrates his Telephone, gives thereupon an explanation and the history of this instrument. “Prof. Poggendorff produces tones in a metal cylinder, the slit up edges of which touch one another firmly, and which is placed loosely round an induction-bobbin through which there goes an interrupted current.” [This occasion was the crowning point of Philipp Reis’s career, and might have proved of even greater importance but for two causes: the inventor’s precarious health, and the indifference with which the commercial world of Germany viewed this great invention. Where the keen insight of Reis contemplated the vast possibilities opened out by the invention of a new mode of inter-communication, others saw only an ingenious philosophical toy, or at best a pleasing illustration of certain known principles of acoustic and electric science. And in spite of the momentary enthusiasm which the exhibition of the Telephone had evoked, the interest in it dwindled away. A few of the public journals of that date, noticed the invention in eulogistic terms and spoke of the prospect it afforded of communication between distant friends and of simultaneous concerts being given in different towns, all transmitted telephonically from one orchestra. But the invention came too early. The public mind was not yet prepared to take it up, and the enthusiasm died away. Still in a few of the more important books on Physics, Acoustics, and Electricity, the matter continued to receive attention. In the well-known Müller-Pouillet’s ‘Textbook of Physics’ (Lehrbuch der Physik) edited by Professor J. Müller; in the ‘Technical Physics’ of Hessler, of Vienna, edited by Professor Pisko; in Pisko’s ‘Recent Apparatus of Acoustics,’ and particularly in Kuhn’s admirable ‘Handbook of Applied Electricity,’ the Telephone was accepted as a definite conquest of science, and was described and figured. From the works named we transcribe the extracts which follow, and which sufficiently explain themselves.] [=14.=] EXTRACT FROM MÜLLER-POUILLET’S ‘TEXTBOOK OF PHYSICS AND METEOROLOGY’ (LEHRBUCH DER PHYSIK UND METEOROLOGIE).
