gram of Fig. 9 belongs. It is treated in detail in Appendix II. 

 The axis OX represents the standard phase of the sending end 

 voltage. The successive maximum cyclic voltage reflections at B, 

 are represented to scale by the vectors Oa, ah, he, etc., as far as the 

 fourteenth inclusive. The vector sum of these {Oa, Oh, Oc, etc.) 

 are given for each step in the process. Table V. in Appendix 11. , 

 shows the maximum cyclic values attained at each stage. This in- 

 creases to iig 796.2 V 1 09°. 49' at the thirteenth reflection. After 

 this, it diminishes shghtly to 795.8 nio°.36' in the fina-1 steady 

 state. The final voltage at B is thus 5.63 times the impressed volt-
