fundamental units are discussed; magnetic circuits and continuous
electric currents treated in detail; electromagnetism carefully studied.
Special attention is given to the physical conceptions involved and
numerous assigned problems exemplify and broaden the theoretical
conceptions. The whole course is introductory to the detailed study
of electrical apparatus and machines.

UNIVERSITY OF VIRGINIA BRANCH OF THE AMERICAN
INSTITUTE OF ELECTRICAL ENGINEERS.
This Branch holds meetings regularly at which various programmes
are carried out. Current literature is abstracted and discussed.
Prominent engineers address the Branch at intervals upon topics
of engineering interest, and members of the Faculty present subjects
of interest which are not in general covered in the regular courses.
