MINERALS OCCURRING IN CANADA. 97 



ships (in Ottawa Co.), and Litchfield (Pontiac Co.), in the province of Qnebec. The 

 townships of North Elmsley and North Bnrgess (Lanark Co.), and elsewhere in this 

 part of the province of Ontario. Very large crystals of pyroxene are not unfrequently 

 met with in the above referred to townships of Templeton, Portland and Wakefield, 

 as also in the townships of Sebaslopol and Blythfield (Renfrew Co.), in the province 

 of Ontario — and a very handsome lilac-colored pyroxene occurs in the Augmentation 

 of the aforementioned township of Grren ville. See also notes to " Augite," " Coccolite," 

 "Diallage," "Fassaite," " Malacolite," "Sahlite." 



210. Pyeriiotite — Occnrs in many localities ; among which maybe mentioned the town- 

 ships of Barford (Staustead Co.) Sutton and Bolton (Brome Co.) where it is associated 

 with copper ores ; St. Francois (Beauce Co.) associated with pyrite, arsenopyrite, 

 etc., and St. Jérôme (Terrebonne Co.) associated with pyrite — in the province of 

 Quebec. Abundantly, more or less associated with chalcopyrite, in McKim and 

 adjoining townships (District of Nipissing) ; accompanying i^yrite in Elizabethtown 

 (Leeds Co.), at Balsam Lake (Peterborough Co.), province of Ontario. A very inter- 

 esting twin crystal found by Dr. Harrington at the Elizabethtown depo.sit (Anal., 

 B. J. Harrington, Rep. Geol. Can., 18*74-75, p. 304), was examined by Dr. E. S. Dana, 

 Am. Journ. Sci., vol. xi, p. 386, 18*76. 



211. Retinalite — Is found, imbedded in crystalline limestone, in the township of 

 G-renville (Argenteuil Co.), and on Calumet Island (Pontiac Co.), in the province of 

 Quebec. Analyses, T. S. Hunt, Geol. Can., 1863, p. 471. 



212. Rhodochrosite — Has not, as yet, been found in Canada in distinct examples, but 

 occurs in admixture with many of the manganese ochres, and is also present, in 

 traces, in some of the altered strata of the Eastern Townships of the province of 

 Quebec. 



213. RiPiDOLiTE — Has, so far, not been identified with certainty as occurring in Canada. 

 A chloritic mineral occurring — in uneven folia, of an olive-green color and pearly 

 lustre — in association with apatite, quartz, pyrite and calcite, in the township of 

 Templeton (Ottawa Co.), province of Quebec, has been examined by Dr. Harrington 

 (Rep. Geol. Can., 1877-78, p. 34 G, and found to have, approximately, the composition 

 of ripidolite. A foliaceous mineral found in a serpentine rock in the adjoining 

 township of Buckingham would, so far as it has yet been examined, also appear to 

 be referable to this species. 



214. Rock Crystal — Is found, in large crystals, at South River (Antigonish Co.) : in 

 perfect crystals at Spencer's Island (Cumberland Co.) : at Sandy and Mink Coves 

 (Digby Co.), etc., in the province of Nova Scotia. In crystals (known as Quebec 

 diamonds) showing unusual modifications in form, in fissures and cavities in lime- 

 stone rocks in the vicinity of Quebec, and in large transparent crystals, in quartz 

 veins, at Harvey's Hill mine (Leeds Co.), province of Quebec. Also in good crystals 

 in cavities of the quartz A'eins of the Bruce mines, Lake Huron, and similar veins at 

 Thunder Bay, Lake Superior, province of Ontario. 



215. RosEQUARTZ — Is found at "Westfield (Queen's Co.) and, in the form of pebbles, near 

 the town of Shelburne (Shelburue Co.), in the province of Nova Scotia. 



216. Rutile — Occurs, in the form of needles in quartz, at Scot's Bay (King's Co.), province 

 of Nova Scotia. In small orange-red grains in the ilmenite of St. Urbain, Bay St.
