AXINITE; Thumerstone ; Thumite ; Yanolite. This sub- 

 stance does not readily yield to cleavage, so as to afford 

 a determination of its primary form from cleavage planes. 

 The primary form best agreeing with those secondary 

 forms under which it generally occurs, is a doubly oblique 

 prism, P on M, 134 40' ; P on T, 115 17' ; M on T, 

 135 10', as measured by W. P.
