✦ Synopsis


other topics of like character.

Some historic notes and an introduction to the mathematical processes employed in the analysis of telephone lines are tolltained in the final section. Needless to say the work of Pupin and the application of electronic amplifiers receive adequate attention.

The work is comprehensive and with its notes and comments highly interesting.
