analogous to syenite or greenstone. They are also said to 

 have been found in a slaty rock with dodecahedral Garnet, 

 and in serpentine along with Saussurite. 



3. It has first been brought from the coast of Labrador 

 in North America, and in reference to this locality, it was 

 named Labradore hornblende ; which name, however, was 

 afterwards exchanged for Paulite, from the island of St 

 Paul. It has been mentioned from Cornwall, where it is 

 said to occur in serpentine, and in primitive slate in 

 Greenland. The variety from the latter place with a blue 

 opalescence parallel to the short diagonal of the prism, 

 which has been considered as a variety of the present spe- 

 cies, presents two faces of cleavage inclined at an angle of 

 about 124|, and must be referred to the species of hemi- 

 prismatic Augite-spar, as has first been observed by Mr 

 BROOKE.
