octahedra closely resembling spinel. Small particles of a greenish mineral of the 

 appearance of augite are also to be distinguished. Spangles of iron are very rarely 

 found in the felspar ; and magnetite is apparently absent. Melts very slowly before 

 the blowpipe. — V. Eounded lump of grey rock from the basalt ridge ; it was 

 covered with a dark green vesicular crust, from 15 to 20 mm. thick. Through the 

 ground-mass, which appears to consist of a felspar, were disseminated numerous 

 brilliant greyish scales, besides some very black magnetite or graphite. Augite 

 sparsely distributed ; abundance of red spinel in some parts, none in others. Melts 

 with great difficulty before the blowpipe. — VI. The dark greenish-brown crust of 

 V, closely resembling that of the rounded masses III. It consists of a felspar 

 inclosing a brown and a green augite-like mineral, and, in places, clusters of 

 granules of spinel. Melts with great difficulty before the blowpipe. — VII. Light 

 grey foliated rock from Ovifak, the exact circumstances of the occiuTence of which 

 are not known. The ground-mass consists of a mixture of a felspar with a grey, finely 

 foliated mineral with graphitic lustre. Red spinel is met with abundantly in both 

 constituent minerals. This variety of rock, like those from" the ridge, is 

 covered with a rust-like crust. It breaks easily, and always parallel to the scales. 

 Before the blowpipe it melts with difficulty on the edges.— VlII. Compact, slightly- 

 weathered breccia, filling a fissure two to three inches wide in the basalt ridge, 

 parallel to which it runs. It is a black granular mass, devoid of metallic lustre, and 

 incloses fragments, some with edges sharp and angular, others with the corners 

 rounded, of a rock exactly like that forming the ridge. — IX. Loose, much-weathered 

 breccia, from the top of the ridge, in irregularly-shaped fragments. It can be 

 broken in pieces with the hand, is much rusted, and closely resembles the product 

 of the oxidation of the metal blocks. Like the preceding specimen, it incloses 

 rounded fragments of the rock forming the ridge. The specific gravity is about 

 midway between that of iron and of magnetite. — X. The broken-up basalt, resembling 

 that of the ridge, inclosed in the weathered breccia IX.
