70. Chromite. 



Small octahedral crystals and aggregates are found, toge- 

 ther with kämmererite, in the serpentine of Washidani, &c., in 

 Bungo. In the Mukawa river in Iburi Province, Ishikawa 

 observed another case of the occurrence of this mineral in 

 common serpentine. 



71. Magnetite. 



Dodecahedral crj^stals of this mineral about 2 cm. in dia- 

 meter are found as druses in the magnetite aggregate found with 

 garnet rock at Ohashi, &c., near Kamaishi in Rikuchû. Minute 

 octahedra of magnetite are enclosed in the chlorite schist of 

 Nogami in Musashi, Sonokigöri in Hizen, &c. Minute crystals 

 in cx) O are found in the massive magnetite of Kurodake in 

 Etclüi, associated with rock crystal, &c., in a garnet rock. 

 The magnetite of Nakakosaka in Közuke Province is fine 

 granular, and found as huge masses in a pale-coloured dioritic 

 rock. Yamashita and Otsuka have studied the magnetic iron 

 sand in the western part of Honshu, &c.
