B. BRECCIATED HEXAHEDRITES. 



These hexahedrites are characterized by a structure which gives 

 them the appearance of being aggregates of individual grains. Not 

 only do apparent outlines of grains occur, but the directions of the 

 Neumann lines are different on the different grains. The size of the 

 grains differs in different falls, but is fairly uniform for meteorites 

 of the same fall. The contour of the grains may be rounded, polygonal, 

 elongated, or ragged, and as a rule the grains are sharply separated 

 from one another. When the divisions between grains widen to a 

 cleft, some accessory constituent usually occupies the gap. Acces-
