ishes and its solubility in triphenylmethane 

 increases as the temperature rises. This 

 state is named S^. The form which con- 

 stitutes the greater part of the liquid from 

 160.1° onward is deep-brown in color and 

 very viscous. Its coefficient of expansion 

 increases and its solubility in triphenyl- 

 methane diminishes as the temperature 

 rises. This state is named S ^. Amorphous 

 sulphur is supercooled S^.
