between the branches o£ — 74 and —242, so that the energy 

 imparted to different branches of —242 is finally concen- 

 trated in the single branch. This point seems to have some 

 signification in solving the problem of atomic structure. 

 Quite close to the principal line lies a strong satellite in the 

 position of — 26. This satellite seems to be split into two 

 branches, of which the negative branch rises almost in 

 contact with the principal P , and after bending takes a 

 course parallel to P_ 1# On reaching this stage, the line 

 becomes very intense, and in high fields it forms a com- 

 panion with intensified —242 on the negative side of the 

 P_ x branch. This is a characteristic feature of the action 

 of strong magnetic force on the green line. The other 

 branch of — 26 seems to run almost parallel to P +1 , but is 

 faint and difficult to observe. 



The + branch of +78 runs parallel to P +1 and becomes 

 gradually strong, that it stands almost symmetrical with 

 — 242 about the principal line P . The —branch of -f78 

 resembles the satellites of 4047. It crosses P +1 and gradu- 

 ally approaches P , in which it is ultimately merged. The 

 position of this line was at first difficult to decipher, but we 

 noticed a slight dissymmetry in the separation of P P + i and 

 P P_i, the latter being somewhat greater. This was after- 

 wards found to be due to the presence of the —branch 

 of +78, by which the centre of the line was slightly dis- 

 placed towards the positive side, giving rise to an apparent 

 dissymmetry about P . 



Of the two 5-branches of + 78, one is difficult to trace, 

 while another branch is somewhat curved. In high fields, the 

 + branches are parallel to P +3 and P +4 , the —branches to 

 P_ 2 and P_ 3 ; thus the separation is probably of the 

 deformed sextet-type, of which the line 4359 of mercury is 

 an example of regular type. Thus the effect of high field 

 on the satellites of the green line is exactly similar in 

 character with that of the violet line ; the different 

 branches of the satellites becoming ultimately parallel to 

 those of the principal, the tendency to parallelism coming- 

 in the earlier stage for ^-components than for the p- 

 components. 



The position of the branches parallel to those of the 

 principal in p- and s-components is as follows : —
