38 P. SCHEI. ON SOME NEW OCCURR. OF TITANITE F. KRAGERØ. 



Almost every crystal shows these forms, with the only ex- 

 ception of jToil that is often wanting. Remarkable is the con- 

 stant occurrence, in this and the last mentioned variety, of |010;, 

 a rare form in titanite. 



The cleavage parallel to jTiij is much pronounced, and pa- 

 rallel to one face of j221| is observed a parting giving exquisite 

 smooth planes — . The nature of the faces is very different: 

 JOlOj, jl31{, and |Tl3' are usually dull or looking varnished, 

 jlllj and jOOlj strongly faceted and giving disturbed signals, 

 jlllj, jT2li, and jTiaj are often very brilliant, jîi2| & |Tl3s 

 both show vicinal faces.
