For comparison we quote the analysis of a "jadeitic" stone axe from 

 Schaffis, Biel Lake, Switzerland (I), made by Laura Hezner' and of 

 "Jadeite" from an erratic boulder, La Téne, Switzerland (III made by A. 

 Frenzel-. Both are bulk-analyses of rocks, but they consist chiefly of 

 pyroxene and contain only accessory garnet and rutile. Ill is the analysis 

 of pyroxene from Saftkjael.
