 to tvi, in Figure 10, after applying the factor e"^^'. The total energy

denser, follow respectively the curves Wt and w, which do not correspond 

 with the cyclic curves vl\ and w of Figure 10, being energy summations 

 instead of instantaneous values. Consequently, the curves of Wr, and 

 w in Figure 10 must be interpreted otherwise than by the application 

 of an attenuation-factor. 



With respect to the phase of the oscillating-current as standard, we 

 have the series of stationarv vector-diagrams of Figure 12. The oscil-
