Mr. Iolo Jones on the Period and Decrement 



above "889, there exists a range of values for R2/L2 over 

 which no oscillations are produced. 



Table II. shows this range of values for various values of 

 k 2 between this limiting value *889 and unity, R4 being kept 

 at zero.

Tables III.- VII. give the values of Jc, n, and 8 for various 

 values of the coupling, a little below and a little above the 

 limiting value, R>/L 2 being given various values ranging from 

 500 to 6000.
