merit of the wavemeter and the corresponding relative deflections of 

 the dynamometer.

 For Determining Damping. 



These results are plotted in the curve of Fig. 4, in which the abscis- 

 sas are A/A,„, and the ordinates D/D m . 



Schmidt's method of getting the damping from this curve consists 

 in determining the width between the two branches of the curve at 

 ordinates .55, .70, and .85, and then making use of a decrement dia- 

 gram which he has computed and plotted in his original paper, to which 

 the reader is referred. This method applied to the present case gives 

 the values in Table V.
