Hematite. 



New Hebrides. 



(PI. iii., figs. 4, 5.) 



A small band specimen from an unknown locality in the New 

 Hebrides was submitted for identification and found to be crystallised 

 hematite, variety specular ii'on, composed of tabulai- crystals measuring 

 up to 15 mm. and smaller equi-dimensional crystals about 8 mm. in 

 diameter. The faces are brilliant but inclined to be curved and the 

 crystals are aggregated into small groups arranged in parallel posilion. 

 Angular measurements were made on one of these parallel aggregates and 

 the forms present were found to be .• (0001), <> (1120), /• (1011), // (2243), 

 the relative development of the forms being appi-oximately as represented 

 in the figures. 



The measured and calculated angles are given in the subjoined table.
