The alternation will therefore pass by way of branch the same time, the magnetic circuit of the other inductiondevice being broken by the position of the armature o, there willbe less opposition to the current in coils m, which will shunt thecurrent from branch c. A reversal of the current being attendedby a shifting of the armatures, the opposite effect is ])roduced. Other modilicationg of these methods are possible, but neednot be pointed out. In all these plans, it will be obseived, there.

Whether the divisi(jn of the currents or waves of current ofopposite sign be effected with absolute precision or not is immaterial, since it will be sutKcient if the waves are only j)artiallydiverted or directed, for in such case the j)reponderuting inliuencein each branch of the c-ircuit of the waves of one sign securesthe same practical results in many if not all respects as thoughthe current were direct and continuous. OBTAINING DIUKCT FROM ALTERNATING CUBRENTS. 417 An alternating and a direct current have been combined so thatthe waves of one direction or sign were partially or wholly over-come l)y the d
