closely allied to some varieties of common asbest. 
—The tremolite (formerly grammatite of Haiiy, 
but now considered as a variety only of amphi- 
bole or hornblende): among the specimens of 
this substance are, the fine fibrous variety, not 
unlike in appearance to some varieties of asbest 
in the opposite glass-case ; glassy tremolite in 
dolomite and granular limestone (see the ad¬ 
joining table-case, No. 21).—The rhoeticite^ a 
mineral, which, according to Werner, is inter¬ 
mediate between tremolite and kyanite, but 
probably is the same with the latter. 
Case 16. Asbest and amianth^'with, other re¬ 
lated substances : among these may be observed 
specimens illustrative of the transition from a 
very close to a loose-fibrous structure ; various 
specimens of the flexible asbest or amianth, with 
some antique incombustible cloth, paper, &c. 
made of it; the varieties called mountain wood, 
mountain cork, or nectic asbest, &c. separate, 
and in combination with other substances.—As 
bordering on the varieties of actinote in the ad¬ 
joining opposite glass-case, we have here the 
diallagite (diallage), the green variety of which, 
called also smaragdite, is considered'by Werner 
as a granular variety of actinote : in combination 
with saussurite (a variety of compact feldspar) it 
constitutes the verde di Corsica. Another variety 
is called omphaciie by Werner.— In its vicinity 
is also placed the axe^stone^ or Punamu-stone, 
thus called after one of the New Zealand Islands, 
where
