Excerpt from A Manual of Telephony

There is perhaps nothing more astonishing in the annals of science than the way in which the use of the telephone has developed. In July, 1877, one of the authors of this book brought the first pair of practical telephones to Europe. It is not too much to say that there are now more than a million in daily use.

The idea of transmitting sound to a distance may be traced back to remote antiquity; it found its first prae tical expression in the construction of the speaking tube, and in more modern times in that of the string telephone.

Excerpt from A Manual of Telephony

In November, 1888, was published one of the volumes of the Specialists Series, entitled The Telephone, the authors being W.H. Preece and Julius Maier, Ph.D. The reception extended to this work was of the most gratifying character; but the rapid strides made in practical telephony since that time, together with the fact that Dr. Maiers services were no longer available, led to the decision that the original volume should not be re-issued, but should be replaced by the present work. We desire here to recognise and acknowledge the use that we have made of Dr. Maiers previous labours, particularly in connection with the earlier portions of this book, which deal principally with historical telephony. No slight difficulty has been experienced in determining what information should be given and what excluded. As, on the one hand a minute and particular description of all conditions is unnecessary for the experienced specialist; so, on tlie other hand, the neglect of minor details may lead to very great inconvenience to others who, in isolated districts, wish to avail themselves of the fruits of the labours of their more favoured colleagues. We have spared no pains to secure such due proportion in the descriptions of the various apparatus and systems as shall meet the wants of both these classes.
