ville (Annapolis Co.), Briar Island (Digby Co.), and many other places in this section 

 of Nova Scotia. More abundantly, however, in the province oi' Ontario, occurring in 

 fine particles, filaments, grains or masses, the latter sometimes more than one hun- 

 dred pounds in weight, in amygdaloidal traps and greenstones, in veins and fissures 

 traversing these, and in sandstones associated with the same, in many localities on 

 the north and east shore of Lake Superior, some of the more important of which are 

 — Battle Ishuid, the Islands of St. Ignace and Michipicoten, also at Mamaiuse and 

 Cape Gargantua. 



82. CoRACiTE — Is said to form a vein about two inches in width, at the junction of the 

 trap and syenite, at Mamainse, east side of Lake Supi-rior, province of Ontario. 



8-3. Corundum — Has been found in small light blue crystals imbedded in crystalline 

 Laurentian limestone, also in rose-red to saj^phire-blue grains, disseminated through 

 a rock made up of felspar, riuartz, calcite, mica and sphene, iu the township of 

 Burgess (Lanark Co.), province of Ontario. 



84. CovELUTE — Occuis in nodular form, with nodules of more or less altered chalcocite, 

 at New Annan (Colchester Co.), province of Nova Scolia. Anal., H. Louis, Trans. N. 

 S. Inst., vol. iv, p. 427, 1878. 



8Ô. Ckyptomokphite — Is found, in conjunction with ulexite, Ilowlite, mirabilite, halite, 

 Arragonite, calcite and selenite, in gypsum deposits at the Clifton quarry, Windsor 

 (Hauts Co.), province of Nova Scotia. Anal., H. How, Am. Journ. Sci., 2 ser., vol.

 small c^uautity only, in .some of the copper deposits of the Eastern Townships of the 

 province of Quebec, as at Acton (Bagot Co.), where it has been observed in the form 

 of cinnabar-red stains irpon blackish shales. 



8*7. Cyanite— Occurs in the form of radiated columnar aggregates of a pure blue, light 

 bluish-grey, and greenish-grey color, imbedded in a granular quartz, on the North 

 Thompson River, British Columbia. Anal., G. C. HoflTmaun, liep. Geol. Can., 1878-79,
