[36] [Professor Pisko seems to have got hold of an unusually unfortunate specimen of the instrument if he could make it neither speak nor sing. His transmitter must have been in exceedingly bad condition to fail so completely.] [37] This error has been copied by Count du Moncel, along with the other defects of the article, into the fifth volume of his ‘Applications of Electricity,’ published in 1878. It is rather amusing now to read, at p. 106, of Du Moncel’s treatise that “Heisler” (_sic_) “pretends” that the telephone of “Reuss,” which “appears” to have been invented “anterior to the year 1866,” was capable of transmitting vocal melodies! Count du Moncel, though he has since posed as an authority on the telephone, did not in 1878 shine in that capacity, for on the very same page of the Count’s book may be found the following astounding sentiment:--“_If it is true_, as Sir W. Thomson has assured us, _that at the Philadelphia Exhibition of 1876 there was a telegraphic system transmitting words_, we may recognize,” &c. Count du Moncel has since found out that it _is_ true that there was a Telephone in Philadelphia in 1876: perhaps he will next discover that “Reuss” did, “anterior to the year 1866,” actually “appear” to transmit not only what “Heisler” “pretends” he did, but that he also transmitted spoken words.--S.

Messel, F.C.S. 6. Herr Heinrich Holt. 7. Herr Heinrich F. Peter. 8. Mr. Stephen M. Yeates. 9. Dr. William Frazer. Professor G. Quincke, _Professor of Physics in the University of Heidelberg_. [Professor Quincke, whose name is so well known in connection with his researches in molecular physics and in many problems of the highest interest to those acquainted with electrical science, was one of those present at the Naturforscher Versammlung held at Giessen in 1864, where Reis’s Telephone was publicly exhibited by its inventor, see page 93, _ante_. His testimony, coming from so high authority, is therefore of exceptional value.] “Dear Sir, “I was present at the Assembly of the German Naturalists’ Association (Naturforscher Versammlung) held in the year 1864 in Giessen, when Mr. Philipp Reis, at that time teacher in the Garnier Institute at Friedrichsdorf, near Frankfort-on-the-Main, showed and explained to the assembly the Telephone which he had invented. “I witnessed the performance of the instruments, and, with the assistance of the late Professor Böttger, heard them for myself.
