(vii) to these results and computing the constants from the first, 

 fourth and sixth observations,* we obtain: 



X X 10^ = 30,830 6i - 488,000 h^ - 53.4. 



In the following table the experimental and calculated values 

 of X X 10^ are compared: 



TABLE XXXIII 



Formula (vii) also applies to 1 per cent solutions of ovomucoid 

 in varying concentrations of KOH and HCl, only in the acid 

 solutions we must replace 6i by ai, the acidity of the solution 

 to which the ovomucoid is added. For 1 per cent ovomucoid 

 in KOH solutions, computing the constants by the method of 

 least squares, we obtain: 



X X 105 = 20,850 bi - 1,250,000 fei^ - 35.6. 



In the following table the experimental and calculated values 

 of X X 10^ are compared: 



TABLE XXXIV 



For 1 per cent ovomucoid in HCl solutions, computing the 

 constants by the method of least squares, we obtain: 



X X 10^ = 41,990 ai - 852,700 ai" - 41.4. 



* These results do not lend themselves to determination of the constants by 

 the method of least squares, since the normal equations are nearly identical, 

 the factors differing only by magnitudes commensurate with the experimental 

 error.
