Art. 7. — K. Yamada 



From the table we see that J^ increases proportionally to the 

 fields applied, as in the case of 4404'75. Plate IX, Fig. 1. 

 The results of the former investigations are: 



The nearest value to my result is that found by King, whose 

 value is in agreement with mine with a discrepancy of 2%. 



(6) ; : 3886-29. 



Intensit}^ 5; sharp triplet; character a. Plate I, Fig. 4; 

 Plate IV, Fig. 4. The fields were determined before and after 

 photographing this line by the aid of i^: 4680* 138 of zinc. But 

 the fields marked with an asterisk were determined by À : 3856'38, 

 taking -g- =20*94, which we shall discuss hereafter. (Table IX 

 and its discussion).
