Found near Dumba'ton and other places in Scotland, at the Cape 
of Good Hope, and in Dauphignj, fometimes fo hard as to ftrike 
fire with tteel, and to admit a fine polifh: colour apple-greeny 
fometimes verging into leefc or olive-green ; the cryftals are 
in groups and confufed,and appear, according to Hauy, to be 
4-fided priims with dihedral fummitsj fometimes they arc 
irregular 6-fldcd plates, and fometimes flat rhnmboidat pa- 
iallelopipeds : the amorphous kind prefents either a foliated 
or ftr’ated texture j the foliated confifting of large or fmall- 
grained dilfinft concretions,- the ftriated of imperfedt flender 
columnar concretions; the tranfverfe fraflure is uneven and 
fine grained : before the blowpipe it foams and fwells more 
than other fpecies, and melts into a brown enamel, fmooth 
on the outfide, but fpongy and porous underneath: fpecific

Found in Tranjf mania near Schebe/ch, mixed fcatteredly with 
the Marnior micana ; the prifms fometimes folitary, fome-- 
times cluftered, 4-fidcd or 6-fided : colour generally whi'e, 
rarely bluKh, fea-green, or ftraw-colour : contain- a larger 
proportion of carbonate of lime than other fpecies, to the 
quantity of 1 3 parts out of 60, and lefs alumina. 
Very brittle, tranfparent, fhiningy ponderous, hardifhy 
flriking fire with llecl, breaking tranfverfely into long 
fplinters, texture foliated in a radiate manner.
