ordinates, the other with those of B + B'. Fig. 3 represents the two 

 curves thus obtained ; by prolonging these, as shown by the dotted 

 lines, two points are obtained, c and d, respectively representing the 

 values of A + A' and B + B', when the abscissa becomes 0, which 

 corresponds with the position of the "limiting point." With a suffi- 

 ciently large-scale plotting, the points c and d are found to correspond 

 respectively with the values 84'5 and 32*5 ; and as at the " limiting 

 point "A = A', and B = B', it thence results that
