Ellenboro, Rutherford Co., North Carolina. 

 Spheroidal mass showing natural and etched sur- 

 faces and fracture. The latter shows the iron 

 to be highly crystalline, and to possess octahe- 

 dral cleavage. (W.) 



Canon Diablo, Arizona. 



*Three complete individuals apparently scaled off 

 from a larger mass. All show the smooth sur- 

 face and characteristic pits of this iron. (W.) 



*Complete individual, ovoid in form. Crust and 

 pits like No. 141. (W.) 



Complete individual, weight, 1013 pounds. (See 

 PI. Ill, Fig. 3.) Besides the shallow pits shown 

 in the figure the mass is indented by deeper cyl- 

 indrical ones, three to four cm. in depth. (W. ) 



Full-sized slab with polished and etched surfaces. 

 The W. f. are very coarse, arranged in approx- 

 imately parallel bands. Large nodules of 

 troilite and flakes of schreibersite are scattered 

 through the mass. (W.) 



*Small, complete individual, like No. 141. (W. ) 



Complete individual weighing 265 pounds. (See PI. 

 Ill, Fig. 3.) The chain by which it is suspended 

 passes through a natural perforation about 3 cm. 

 in its smallest diameter. (W. ) 



*Full-sized slab showing polished and etched sur- 

 faces like No. 144. (W.) 



Nearly complete individual showing deep and shal- 

 low pits. One etched surface exhibits nodules 

 of troilite and indications of crystalline struc- 

 ture. (W.) 



Complete individual, sub-cylindrical in form. Ex- 

 hibits the characteristic pittings. (K.) 



Thick slab, polished, showing nodules of troilite. 



(K.) 



Hemispheroidal mass. One polished surface shows 

 troilite nodules. (K. ) 



*One large and several small fragments with natu- 

 ral surface. (K.) 



*Complete individual showing pits and natural sur- 

 face. Apparently scaled from a larger mass. (W. ) 



El Capitan Mts., New Mexico. 



Slab showing crust and polished surface.
