NATURE 



[January 27, 1898 



measurements concerning radiation phenomena in the magnetic 

 field. Photographs have been taken of the outer components 

 of the magnetic triplet. Measurements of the distance of the 

 components for lines in the violet and ultra-violet parts of the 

 spectrum ^re communicated. In the cases of the metals 

 examined — viz. zinc, cadmium, copper, and tin — the magnetic 

 change is of the same order of magnitude in all of them, and 

 independent of the atomic triplet. Some lines are not affected 

 by magnetism.
