344 Mr Purvis, The influence of a very strong magnetic field 



Ruthenium. 



The lines were identified by comparison with the measure- 

 ments and descriptions of Exner and Haschek (Site. d. k. Ahad. 

 Wien 1896, vol. cv. n A . abth. p. 707. 



The following lines are divided into triplets. The middle 

 constituent is generally the strongest ; and relative differences of 

 intensities are marked by approximate numbers as well as by 

 different appearances in the diffuseness. The middle constituent 

 vibrates parallel, and the two outside ones perpendicular, to the 

 lines of force. The distances of the two outside constituents were 

 measured from the centre of the middle one.
