74 HOFFMANN'S LIST OF 



crystals, with rouuded angles, together with grains of purple lluorite, and crystals of 

 black spiuel, imbedded iu a yellowish crystalline limestone, in the township of Ross 

 (Renfrew Co., Ont.) ; and crystals of l)lue apatite and quartz are imbedded in a 

 coarsely cleavable, sky-blue calcite at the Calumet Falls iu the township of Litchfield 

 (Poutiac Co., Que.). Small hexagonal prisms, sometimes an inch iu length and 

 one or two liues in diameter, transparent, of a pink or purple color, with surfaces 

 often dull, and angles rouuded, occur, in association with crystals of augite, in an 

 intrusive mass of fine grained, grey dolerite at St. Roch, on the Achigan River,

 the composition of Canadian apatites, G-. C. Hoffmann, Rep. Geol. Can., 187*7-78 

 pp. 1-14 H. 



28. Aphrodite — Is found filling fissures in the massive pyrallolite of the township of 



Grenville (Argenteuil Co.), iu the province of Quebec. Anal., T. S. Hunt, Geol. 

 Can., 1863, p. 473. 



29. Apophyllite — Green and white crystals, aggregated iu plates or iu square prisms, 



occur at Two Islands and Cape d'Or (Cumberland Co.), Blomidou (King's Co.), and 

 Margaretville (Annapolis Co.), iu the province of Nova Scotia. Also, in foliated 

 masses or plates, often of a red color, in association with calcite, on Prince's Location, 

 Spar Island, Lake Superior, province of Ontario. 



30. Argentite — Occurs, with native silver, chalcocite, sphalerite, etc., in a vein of calcite 

 at Prince's mine ; with native silver, iu a vein of barite, celestite and calcite, on 

 Jarvis Island ; with native silver, sphalerite, and a little galenite and pyrite, in a 

 vein of barite and calcite on McKellar's Island ; and with sphalerite, pyrite, niccolite, 

 etc., in a veinstone consisting of calc-spar, bitter-spar and quartz, on Silver Islet, 

 Lake Superior. "With native silver, in a gangue of calcite, at the Duncan mine — also 

 at the Rabbit Mountain, Porcupine, Beaver and other mines in the district of 

 Thunder Bay (Lake Superior), province of Ontario. 



31. Arquerite — Is found with alluvial gold upon Vital and Silver Creeks, Omenica 

 District, province of British Columbia. Anal., H. G. Hanks, Dana, Min., App. iii, p. 

 4, 1882. 



32. Arragonite — Is met with, iu the form of acicular crystals, varying iu size from 

 microscopic minuteness to an iuch or more iu length, lining fissures or cavities in the 

 ankerite, or implanted irpon barite or calcite, in the ankerito deposits of Londonderry 

 (Colchester Co.), province of Nova Scotia. Has been observed forming stalactites and 

 delicate fibrous masses in a calcareous rock in the township of Triug (Beauce Co.), 

 province of Quebec — and sparingly amongst the Lake Superior traps, province of 

 Ontario. 



33. Arsenic. Native, — Is found, in veins, seven miles up Watsou Creek, west side of 



Fraser River, twenty-five miles above Lytton, province of British Columbia. Ann. 

 Rep. Geol. Can., vol. ii, p. 9 T, 1886. 



34. Arsenopyrite — Is of exceedingly common occurrence iu the gold-bearing quartz 

 bauds of Nova Scotia. Is forind, according to Dr. Hunt, well crystallized, with galena, 

 iu a quartz A'ein on the Chaiidière in St. Francis (Beauce Co.) ; and still more 

 abundantly in small crystals, in association with galena, in a large vein of quartz on 

 Moultou Hill, near Lennoxville (Sherbrooke Co.), province of Quebec. Occurs in
