I have been more than once assured, on what seemed to be 

 good authority, that rich deposits of cinnabar 

 cinnabaf 11 ° f had been discovered in the Shan States, but 



the material on inspection turned out invariably 

 to bd nothing more than red clay. The brilliant red ' Terra Rossa ' 

 of the plateau, when washed into a fissure in the limestone, and 

 exposed by denudation in a cliff section, may easily be mistaken for 

 this mineral ; but its low specific gravity, as compared with that 

 of cinnabar, at once serves to distinguish it.
