METEORITES OF NORTH AMERICA. . 113 



CASEY COUWTY. 



Casey County, Kentucky. 



Latitude 37 15' X., longitude 95 W. 



Here also Casey County, Georgia. 



Iron. Coarsest octahedrite (Ogg) of Brezina; Bendegite (type 6) of Meunier. 



Found and mentioned 1877. 



Weight, assignable, 732 grams (1.5 Ibe.). 



The first mention of this meteorite is by Smith, 1 who simply states that he had received 

 it as one of two new meteoric irons, analyses and descriptions of which would be published 

 shortly after. Such publication seems, however, never to have been made. All that is further 

 known of the meteorite consists of brief descriptions of its intimate structure by Brezina * and 

 Meunier. 4 These are as follows" 



A fragment in the Vienna museum shows very regular, broad Widmannstatten figures, with bands of an average 

 width of 2 mm.; kamacite is almost exclusively exhibited, with unusually sharp etching figures; taenite and plessite 

 only in traces, schreibersite and troilite not perceptible. 8 



Breadth of laminae 1.8 mm. Hatching fine and distinct; fields very scarce.* 



A very beautiful specimen of Bendegite remarkable for the extreme size of the kamacite bands, some of which 

 measure as much as 5 mm. in width. It shows the Neumann lines in much smaller numbers than the Bohumilitz 

 iron and has many specks of phosphides scattered over them. 4 



Wulfing 5 lists 732 grams as present in collections. Of this amount the Harvard collec- 

 tion possesses the largest section.

CASTALIA. 



Nash County, North Carolina. 



Here also Nash. 



Latitude 36 11' N., longitude 77 50 7 W. 



Stone. Brecciated gray chondrite (Cgb) of Brezina; Canellite, (type 48) of Meunier. 



Fell 2.30 p. m., May 14, 1874. 



Weight, 73 kgs. (16 Ibs.). 



This meteorite was first described by Smith * as follows: 



The meteorite of Nash County, North Carolina, fell May 14, 1874, at 2.30 p. m., near Castalia, in latitude 36 11' N., 

 longitude 77 50' W. Its fall was accompanied by the successive explosions common in such cases, and with rum- 

 bling noises which lasted about 4 minutes, not unlike the discharge of firearms in a battle a few miles off. 



The stones that fell must have exceeded a dozen or more; three only have been found, and they give evidence 

 that the territory over which the fragments fell was 10 miles long by over 3 miles wide. Although occurring in the 

 day the body appeared luminous to some observers. The three stones found weighed respectively 1 K., 800 grams, 

 and 5.5 K. 



They are of common aspect. They have a dull exterior coating, which in some places does not entirely cover the 

 stones, there being a few spots of the fractured surface, less than 1 cm. in diameter, over which the fused matter form- 

 ing the coating is scattered in the form of pear-shaped beads. In one or two crevices some of the fused matter of the 

 coating has penetrated 5 mm. below the surface. 



The interior in many parts is of a dark gray color, and in other parts quite light; the principal cause of the dark 

 color is doubtless the larger amount of nickeliferous iron in that part, and in the lighter portion there are some white 

 spots of a mineral that is doubtless enstatite. 



The specific gravity of the stone is 2.601. Its composition is as follows: 



Nickeliferous iron 15. 21 



Stony minerals 84.79 



The nickeliferous iron consists of: 



Iron 92. 12 



Nickel 6. 20 



Cobalt 41 



Copper and phosphorus (not estimated).
