/The two outer constituents were sharper and stronger than 
the middle one which was very diffuse and at least as wide 
1 as the distance between the two outside ones. The two 
| sharp ones vibrate parallel to the lines of force. The broad 
1 and diffuse middle constituent appeared to be further sub- 
\ divided, but it was too weak to be distinguished accurately.
