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
