Within tlie area represented on the rough chart, not exceeding 50 

 square metres, the following blocks of meteoric iron were found by 

 the Expedition of 1870 :

 Several lenticular pieces of iron from the basalt vein, of 3-4 inches 



thick, weighing altogether ... ... ... about 100 „ 



The 0"\afak iron is extremely crystalline and brittle, so that 

 smaller pieces may be broken with a hammer, and, with the ex- 

 ception of the little bits of basalt on or near the surface, is not mixed 

 with any silicates visible to the naked eye. The iron from the 

 basalt ridge differs from the other by a rougher fracture and greater 

 toughness. With the naked eye one can seldom discover any 

 nodules of troilite or iron- sulphide. In the weathered detritus, on the 

 other hand, a few black magnetic grains were found, with strongly 

 reflecting facettes and octahedral surfaces, which on examination 

 we found to be magnetite. When cut and polished, the different
