Este crystal mostra, portanto, junto 

 com o octaèdre predominante (111) eodode- 

 caedro (110), os seguintes triakisoctae- 

 dros — V3 O (553). '/.. O (774), 7. O (552), 

 30(331)e4 0(441). 



N'um outro fragmento, que se acha des- 

 envolvido como octaedro não comprimido 

 muito rico em faces, porém com as faces 

 curvadas e muitas vezes quebradas, foram 

 achadas, além das formas acima menciona- 

 das, faces hexakisoctaedricas sobre es ân- 

 gulos octaedricos. 



As formas observadas nos crj'staes de 

 chromite do ferro de Bendegó são, portan- 

 to, as seguintes : 



This crystal shows therefore ^yith the 

 predominant octahedron (111) and the dode- 

 cahedron (110), the following triakisocta- 

 hedra— »/, (553), '/, (774), % (552), 

 3 0(331), and 4 0(441). 



On another fragment which is developed 

 as an uncompressed octahedron very rich 

 in faces, but with the faces curved and 

 often broken, there were found in addition 

 to the above forms, very small hexakisoc- 

 tahedral faces on the octahedral angles, 



Tke forms observed on the chromite 

 crystals of the Bendegó iron are then as 

 follows: 



Ü (111) predominant. 

 coO (110) always present. 

 ocOx (001) very rare.
