THE RICHARDTON METEORITE 435 



cross- veins and offset by one. The veins in this specimen seem to 

 be composed largely of troilite. Troilite is disseminated through- 

 out the stone and forms ledges along the veins. 



3. The largest member of Kern's collection is a well-crusted 

 specimen, bounded by one fiat side and a hemispheroid. The 

 fiat surface appears to be a fracture plane following a troilite 

 vein. The stone weighs 1,357 g^- 



4. A seven-sided boloid found by Nickolas Kuntz, weighing 

 2 lbs. 10 oz. (1,192 gm.), is covered with shallow depressions of 

 the common finger-print type. It shows several veins of more 

 than one group. There is no smooth face which may be inter- 

 preted as that sheltered during flight. 



5. Preserved at the University of North Dakota is a very 

 black coated specimen found by Bernard'Kuntz, weighing 1,022 gm. 

 One side is smooth, showing clearly the traces of intersecting veins, 

 and the other faces are pitted with shallow depressions. Either 

 the smooth face was the side away from the rush of air during 

 flight, or it is of earlier origin than the rough faces, which may 

 be secondary surfaces fused over after disruption during passage 

 through the atmosphere. 



6. Fourteen small pieces weigh 515, 498, 349, 312, 309, 305, 

 240, 232, 207, 168, 163, 161, 127, and 123 gm. respectively. 

 These specimens are rounded boloids covered with fused crust, 

 angular fragments completely covered with fused crust of various 

 degrees of denseness, pieces broken either by imp9,ct with the 

 ground or during examination by the finders, and combinations 

 of these groups. In many cases troilite in melted blebs embosses 

 the fused surfaces, indicating that many secondary faces follow 

 the planes of veins. 



This group of small specimens furnishes evidence of at least 

 three degrees of fusion. First, there are black faces which are 

 very smooth and show the traces of veins as welts, apparently 

 sides protected from the direct impact of air in flight. Other 

 black faces are dappled with small finger-print-like depressions, 

 lumps and depressions being equally covered with fusion crust, 

 having been corroded apparently by the blast of hot air com- 

 pressed in front of the meteorite during its passage through the
