96 ■ HOFFMANN'S LIST OF 



fouud iu association with pyirhotite, chalcopyrite, some pyrite, etc, at the miues of 

 the Canadian Copper Company, Sudbury, District of Nipissing, province of Ontario. 

 Anal., F. W. Clarke and C. Catlett, Am. Jouru. Sci., 3 ser., xxxvii, p. 0*72, 1889. 



203. Prehnite — Occurs chiefly iu the trap rocks of Lake Superior, sometimes formin^^ 

 distinct veins, as on Slate Eiver an atllueut of the Kaministiquia, and with imbedded 

 nodules of native copper on an island near St. Ignace — province of Ontario. It has 

 also been found in the Laurentian of the township of Templeton (Ottawa Co.) in the 

 province of Quebec. Analyses, E. J. Chapman, Can. Jouru., 2 ser., vol. xii, p. 26*7, 

 18G9 : B. J. Harrington, Hep. Geol. Can., 1811-1S, p. 34 a. 



204. PriEUDOMORPHOUS QUARTZ — Fine specimens of quartz pseudomorph after chabazite, 

 have been found at Horse-shoe Cove, Cape d'Or, and of quartz pseudomorph after 

 stilbite, at Clarke's Head (Cumberland Co.), province of Nova Scotia. Silicified wood 

 is found in the vicinity of the Elbow of the South Saskatchewan Kiver, and very 

 characteristic specimens of the same at Ross Coulée, Irvine, District of Assiuiboia, 

 North-west Territory. 



205. PsiLOMELANE — Occurs, in association with pyrolusite, at Douglas, Hants county, 

 province of Nova Scotia. 



206. Pyrallolite — Occurs in beds in the crystalline limestone of Grenville (Argenteuil 

 Co.), and Clarendon (Pontiac Co.), in the x^roviuce of Quebec — also in the townships 

 of Ramsay (Lanark Co.), and Rawdon (Hastings Co.), in the province of Ontario. 

 Analyses, T. S. Hunt, Geol. Can., 1863, p. 471 — and of a specimen from Portage du 

 Fort, township of Clarendon, B. J. Harrington, Rep. Geol. Can., ISTO-tT', p. 484. 



20*7. Pyrite — Is very widely distributed throughout the Dominion. The iollowing are 

 a few ot the localities where it is met with in a crystalline form : — in fine crystals at 

 La Have (Lunenburg Co.) and Seven Mile Plain (Hants Co.), in the province of Nova 

 Scotia — in large cu.bical crystals in a vein of copper ore iu the township of Melbourne 

 (Richmond Co.), province of Quebec — in perfect octahedra at Elizabethtown (Leeds 

 Co.), also in a crystalline form in many of the veins and gneissoid rocks of the town- 

 ships of Madoc, Elzevir and Tudor (Hastings Co.), and in the trap dykes of Lakes 

 Superior and Huron ; province of Ontario. 



208. Pyrolusite — Is met with near Kentville (King's Co.), at Springville (Pictou Co.), 

 Musquodoboit (Halifax Co.), Onslow (Colchester Co.), near Amherst (Cumberland Co.) 

 and at Walton and other places, especially at Teny Cape, iu Hants county, province 

 of Nova Scotia. This mineral also occurs at several places iu the counties of "West- 

 moreland, Albert, St. John and King's, — the most important deposit being at 

 Markhamville, in the parish of Upham, King's county, — in the province of New 

 Brunswick. 



209. Pyroxene — Is of common occurrence, especially amoug the rocks of the Laurentian 

 system, where it not unfrc(xuently forms beds, or large segregated veins, which 

 sometimes consist of pure pyroxene, at other times of pyroxene in admixture with 

 other minerals, constituting pyroxeuite. It also sometimes occurs disseminated in 

 in beds of magnetite and, in the form of grains and imperfect crystals, it is common 

 in the beds of limestone. Among the numerous localities of its occurrence may be 

 mentioned : — Kildare (Joliette Co.), the townships of Argenteuil and Grenville 

 (Argenteuil Co.), Buckingham, Templeton, Portland, Wakefield and adjoining town-
