Ma;^netic Separations of Iron Lines in Different Fields. (J3 



experiment goes, and some others, giving complicated or dift'iise 

 resolutions, show deviations from the proportionahty. 



r)6]5-66L 5328-06, 4375-934, 4299-26, 4260-48, 4235-94, 

 4219-36, 4199-09, 4181-76, 4118-552 appear as sharp triplets, the 

 separations being proportional to tlie magnetic field, but the 

 values of the specific separations are different. The results 

 with 5232-957, 4957-62, 4920-52, 4891-51, 4583-83, 4476-03, 

 4466-556, 4427-314, are not as exact as for the lines mentioned 

 above, but the separations are approximately proportional to the 

 magnetic field notwithstanding some possible disturbances of the 

 neighbouring lines, or probably complicated separations measured 

 as tiiplets maj^ be expected for some lines. 



5371-495, 5269-53 and 5167-492 show some sudden fall of 

 the specific separation at about 7000 gauss. Tliough the fall of 

 the first is considerable, that of the last is only slightly noticeable. 

 The fall of 5269-53 may be caused by the disturbance of the 

 neighbouring line 5270-35, so that it needs n"iore experiments 

 with different instruments to decide its character. 



5586-772, 5572-86, 4143-88, 4132-08 and 4005-26, appear as 

 diffuse triplets in weak fields. In the field above 20000 gauss, three 

 of them are resolved into many components, the type of resolution 

 of 4132-08 and 4005-26 being similar, though the latter was not 

 measured exactly. Judged from their similar appearance, the first 

 two lines also may give some complicated separations in strong 

 fields. 



The broadening of the components of 4528-622, 4494-572 

 and 4282-408 also seems to indicate some complicated resolutions. 

 The curvatures in the separation diagrams may be due to the 

 complicated resolutions, but the result of van Bilderbeek-van 

 Meurs and of Graftdijk show that they are triplets even in the 

 field of 32040 gauss. 



5455*614 (quintuplet) and 5227*20 (triplet) show wavy 

 fluctuations in the specific separations of the ?i-components, the 

 separation of the jp-components of the former being proportional 

 to the magnetic field, /»-components of 5446-92 and 5397-12 also
