broken-line curve in fig. 6 the correction indicated by the full-line 
curve. At the starting point and the end the correction is zero. At 
the highest point with an ordinate « we get a correction: 
a(5 + 5):2 X 200=1/,, a, or 2.5 °/, 
of the maximum ordinate. 
In my experiments I used a condenser of 2 mikrofarad, A and r 
being 10° Ohm each. The oscillographic record was made with a 
stringgalvanometer. Fig. 7 gives an example of the curves obtained 
in this way.
