 bronzite chondri have less glass than those of chrysolite. Mono- 

 somatic chondri of bronzite have never been observed, the large

crystal individuals showing, as a rule, no tendency to a spherical 

 form. Besides bronzite chondri having an eccentric arrange-

 and these may pass into those which have a netted appearace 

 from crossing fibers. Such chondri, cut at right angles to the 

 fibers, show the fibers to have a concentric arrangement. The
