Collecting results, we have 



For S — T #orO=C. For 160.(57. 



a = +G1.0 div. = + 30.7 ^ a = —474.2 div. = —239.1 fx 



Whence h = -j-32.10 div. = -|-16.18 /x 



For S — as. 



a = +488.7div. = +246.3/i a = —93.1 div. =—46.9^ 

 Whence b = +34.90 div. = +17.59^ 



For S—R, 



a = +429.8 div. = +216.6^ a = —133.6 div. = — G7.3/x 

 whence b = +33.80 div. = +17.04/X 



We have therefore, from these absolute coefficients, the following 

 relative values.

Combining these values with the relative values found from the 

 observations with the universal comparator, we have finally the fol- 

 lowing values for the absolute coefficients : —
