Dr. L. Silberstein on Radiation from 



vol. xxxviii. p. 407), coordinating this line with i = 35, i. e. 

 writing \ 35 = H 35 = •365680. By Euler's formula, 



w 35 =lll-517574*=35-497146 w. 



These figures give 



R=13'36722; log 10 (^^) =0-9432206. . (50) 



With these values of y and R formula (47) gives the 

 results collected in Table VI., which requires no further 

 explanations.
