Mr. H. Baverman, in exhibiting a remarkable Crystal of Cinnabar 
from the mercury-mines in the province of Kwei-chau (China), 
observed that it was a completely developed penetration-twin of two 
rhombohedra, attached to a mass of crystalline quartz. He drew 
attention to the simple character of the form from this locality, as 
compared with those of the crystals from Almaden and Avala. |
