ON THE USE OF EQUIVALENT FACTORS 



The mean value of H= ^ for the equations (1), (5), (7), and (10) is 



H = — or < — , 



200 100 



as required by (28). 



For the second indeterminate d'y, the favorable equations are (5), (7), (9), (10). 

 The unfavorable ones are (2), (-i), (8), and (11). 



(Q) = 10600000,
