MINERALS OCCURRING IN CANADA. 93 



pegmatite vein (described in uote to "Albite"),iu the township of Villeueuve (Ottawa 

 Co.), province of Quebec. A rose-colored mica, closely resembling-, if indeed not 

 identical with, the rose-colored miiscovite of Goshen, Mass., has recently been met 

 with by Mr. C. W. Willimott, in the township of Villeneuve (Ottawa Co., P. Que.). 

 It was associated with pale groen muscovite, in a matrix composed of albite with 

 a little white translucent c[uartz. 



178. Nail-head-spar — Very fine specimens of nail-head-spar are found at Teny Cape, 

 Hants county, in the province of Nova Scotia. 



1*79. Natrolite — Handsome specimens of this mineral are found at Swan Creek (Cum- 

 berland Co.), Cape Eloinidon (King's Co.), and Gate's Mountain (Annapolis Co.), etc., 

 in the province of Nova Scotia. It occurs, associated with aualcite, in some of the 

 dykes cutting the Trenton limestone at the reservoir extension, Montreal (Hochelaga 

 Co.), province of Quebec. Anal. B. J. Harrington, Rep. Geol. Can., 1874-75, p. 303. 



180. Nephelite— Is stated, by Dr. Hunt, to occur in white crystals, with small grains of 

 blue sodalite, in the nepheline syenite of Brome Mountain (Brome Co.), it also occurs, 

 as a constituent of a similar rock, at Montreal (Hochelaga Co.), and Bdœil (Rouville 

 Co.), province of Quebec. See also note to " Elaeolite." 



181. Nephrite- This mineral has been found by Dr. G. M. Dawson, in the valley of the 

 lower Fraser River (British Columbia), in the vicinity of Lyttoii, on the site of an 

 abandoned Indian village, in small water-worn boulders, evidently derived from the 

 beaches of the river, some having been merely more or less broken, whilst others had 

 been sawn or otherwise partly manufactured into implements (Can. Rec. Soi , vol. ii, 

 p. 364, 1886-87). It has aîso been found (as first announced in Science, April 20, 

 1888), by Dr. G. M. Dawson and Mr. W. Ogilvie, on the Lewes River, a tributary of 

 the Yukon, North-west Territory (Ann. Rep. Geol. Can., vol. iii, p. 38 V,, 1887), but 

 has not as yet been found in si/it. 



182. Niccolite— Has been found, in admixture with domeykite, in a vein cutting a bed 

 of amygdaloid on Michipicoten Island, Lake Superior, province of Ontario. Anal., 

 T. S. Hunt, Geol. Can., 1863, p. 506. 



183. Nitre— Has been found in cavities in calcareous tufa, on the Nazco River, and has 

 also been met with at Big Bar, Fraser River, province of British Columbia. 



184. Obsidian— Is found in large and small masses ou the higher eastern slopes of Il-ga- 

 chuz Mountain, but the most notable locality for this mineral is the mountain named 

 Beece or Anahim's Peak, an isolated summit between the Il-ga-chuz and Tsi-tsutl 

 Mountains, in the upper Blackwater country (G. M. Dawson, Rep. Geol. Can., 1876-77, 

 pp. 78,79) : it also occurs at Tsooskatli, the upper part of Masset Inlet, (on a small 

 islet north-east of Tas-kai-guns), Queen Charlotte Islands (id.— ib., 1878-79, p. 88 b), 

 and other localities in British Columbia. 



185. Octahedrite — Is reported, by Prof How, as occurring in small but fine crystals, in 

 quartz, at Sherbrooke, Guysborough county, province of Nova Scotia. 



186. Oligoclase— Occurs in more or less perfect crystals, in groups, of a white or faintly 

 greyish-white color, in the township of Hull (Ottawa Co.), and a white, rarely green- 

 ish or greyish, felspar, having the composition of oligoclase forms, with black horn- 

 blende, the intrusive diorite of Mount Johnson (Iberville Co.), province of Quebec. 

 A white to pale grey felspar, also referable to this species, is the constituent of a
