THE BOND SPRINGS STONY METEORITE 
Morven (New Zealand) aerolite (8), and from tlie Eosebud 
(Texas, IJ.S.A.) aerolite (2), but a few are difficult to dis- 
tinguish from the granular groundmass, owing to similarity 
in composition and in state of fracture.

Sections or Chondrules. 
Black areas represent metal and pyrrhotite ; dotted areas, 
silicates in the matrix. 
1. Polysomatic composite chondrule; diameter, 0 2 mm. A ring of 
clear olivine grains (o) surrounds finely fibrous enstatite (e). 2. Poly- 
somatic chondrule of sub-radiate enstatite crystals (e) ; diameter, 0 5 mm. 
Minute grains of dusty matter crowd portions of the cleavage lines and 
crystal boundaries. 3. On left, monosomatic chondrule of barred (laminated) 
enstatite (e) ; size 0 8 x 0 5 mm. On right, cryptocrystalline chondrule (c) ; 
diameter, 0-3 mm. Olivine grains (o). 4. Bottom right, monosomatic 
chondrule of radiating enstatite fibres (e) ; diameter, 0 5 mm. Top left, 
polysomatic chondrule composed of several olivine grains which extinguish 
in different positions; size, 07 x 0 4 mm.
