Its behavior before the blowpipe is the same as that of other 
forms of spodumene. When heated to redness in the flame 
well to chromium as to vanadium. :

The specimen analyzed was of the paler variety. There 1s 4 
trace of potash in the soda. ; 
he crystals when cut and polished resemble the emerald in 
luster, though the color is not so intense as in the finest variety 
of the latter gem. There is reason to hope that further explora- 
tions may bring to light crystals of a size and beauty that will 
make them valuable as gems, and for this reason T have 
thought it proper to give this variety of spodumene a distinct 
name. I therefore propose the name of Hiddenite, after the 
indefatigable mineral explorer who has directed our attention 
to it.
