Dra eeEs iii Kobell has given this name to a variety of what has pee ; 
tofore been considered as tantalite, from Tammela in Finland. The specific gra 
by Rose, Jac 
from 7°38—7'5. The pes of the streak blackish- e fro! 
Tammela analyzed by Jacobson was dark brownis a . In other respects dianite 
corresponds perfectly in an characters with tantalite. Von Kobell, however, 
finds it to contain a new metallic acid belonging to the same group as tantalic an 
columbic acids, Pye oe calls dianie acid, an ‘the uthor has also discovered this 
acid in euxenite, zeschivite and samarskite. For a description of the chemical
