Generally speaking, all the hexahedrites found in central Europe, 

 Spain, and Russia follow a pattern of alignment which is also 

 characteristic of those found from Mexico to Oklahoma and from 

 Alabama to Pennsylvania and is also evident in those discoveries in 



Table 12. — Data on European hexahedrites.

Argentina and Australia. This agreement — alignment in a north- 

 east-southwest direction — would not seem to be merely coincidence. 



AFRICA 



Although only six African hexahedrites are known (table 13; fig. 

 8), two pairs occur sufficiently close together to suggest that they fell 

 as separate showers. These are the Bellsbank and Hex River irons 

 in South Africa and the Chinguetti and Siratik in northwest Africa.
