 of previous specimen. (K. ) 



Taborg, Ochansk, Perm, Russia.

 thick, dull-black and blebby. Interior of stone 

 light bluish-gray. Shows brecciated structure.

Pipe Creek, Texas. 



Irregular fragment, with one polished surface. A

 metallic grains. (K.) 



Mighei, Southern Russia.

 aceous. (W.)

 Chondri of lighter color are distributed through 

 the mass. (K. ) 



Leland, Winnebago Co., Iowa. 



609 complete individuals, ranging in weight from 

 one-tenth of an ounce to ten pounds each. They 

 exhibit almost every variety of shape and degree 

 of surface fusion. From the fully rounded 

 specimens with thick, black crust there is every 

 gradation to those whose rough surface is only 

 slightly blackened, indicating that they separated 

 from other masses only a short distance before 

 reaching the earth. The interior, where seen, 

 is light gray, with coarse, metallic particles. In 

 the group is the stone which fell into a hay- 

 stack without setting it on fire. (See PI. V, Fig. 

 2.) (K.) 



*57 complete individuals, all of small size. (W.) 

 Complete individual, with small, conical pittings 

 resembling rain drop impressions. (W.) 



Farmington, Washington Co., Kansas. 



Fragment from interior, having the appearance of 

 a dolerite of dark-gray color and splintery frac- 

 ture. Contains white, radiated chondri. Bronze- 

 yellow metallic grains are numerous. (W. ) 



*Like previous specimen, but showing smooth 

 crust which can be readily scaled off in cer- 

 tain spots. (W. ) 



Thin slab, polished, showing white and dark 

 chondri, and various grains of nickeliferous iron.
