lOO HOFFMANN'S LIST OF 



235. Sperrylite — This recently discovered aud highly iuterestiug miueral, arsenide of 

 platinum, was found at the Vermillion mine, township ofDeuison, District of Algoma, 

 province of Ontario. Anal., H. L. Wells, Am. Journ. Sci., 3 ser., vol. xxxvii, p. G7, 

 ]889 : on the crystalline form of Sperrylite, S. L. Peufield, ibid, p. 71. 



236. Spessartite — Is found, together with black tourmaline, urauiuite, mouazite, etc., 

 in a coarse pegmatite vein — composed of microcline, albite, muscovite and white aud 

 smoky-brown quartz — in the townshij) of Villeneuve, Ottawa county, province of 

 Quebec. 



23*7. Sphaerostilbite — Has been met with by Prof. How, at Hall's Harbor, King's county, 

 province of Nova Scotia. 



238. Sphalerite — Is somewhat widely distributed, being found, but most frequently in 

 small quantities only, in all the provinces of the Dominion. It is met with, in 

 greater or less abundance, in almost every metalliferous vein which has been opened 

 on the east and north shores of Lake Superior, aud an important deposit of the same 

 is situate some eleven miles north-east of Rossport (formerly McKay's Harbor) on the 

 north shore of that lake, province of Ontario. Also occurs in quantity in the town- 

 ship of Calumet — where it is associated with more or less galenite aud a little pyrite, 

 — Pontiac county, in the province of Quebec. " 



239. Spinel — Small translucent octahedrons of blue spinel are found in a bed of crystal- 

 line limestone in the seigniory of Daillebout (Joliette Co.), in the province of Quebec. 

 Large and not unfrequeutly very symmetrical black crystals, sometimes an inch or 

 even two inches in diameter, occur in crystallized limestone in Burgess (Lanark Co.), 

 aud similar crystals, though less perfect, are found, together with lluorite, apatite aud 

 crystals of white orthoclase, in a vein of flesh-red calcite in the township of Ross, 

 Renfrew county, province of Ontario. 



240. Spodumene — Is said, by Dr. Hunt, to have been observed in a small rolled mass of 

 granite near Perth, Lanark county, in the province of Ontario. 



241. Staurolite — Occurs in mica-schists of Moore's Lake, near to Moore's Mills, Charlotte 

 county, province of New Brunswick. 



242. Steatite— See note to " Talc." 



243. Steeleite — Is fo'and imbedded in rod clay in cavities in Triassac trap, at Cape Split, 

 thirteen miles west of Cape Blomidon, King's county, province of Nova Scotia. 



244. Stellarite — The name given by Prof. How to the so-called "stellar" or "oil-coal," 

 which occurs with bituminous coal (in a seam five feet thick, of which one foot ten 

 inches are stellarite) at the Acadia mines on the Acadia Coal Company's area, Pictou 

 county, province of Nova Scotia. Analyses, H. How, Min. N.S., p. 21, 1809. Sir 

 William Dawson, referring to this substance (Acadian Geology, 3rd éd., 1878, p. 339) 

 says : — " The material known as stellar-coal is, as I have maintained in previous pub- 

 lications, of the nature of an earthy bitumen ; and, geologically is to be regarded as 

 an uuderclay or fossil soil, extremely rich in bituminous matter, derived from decayed 

 aud comminuted vegetable substances. It is, in short, a fossil swamp muck or mud 

 which, as I have elsewhere i^ointed out, is the character of the earthy bitumens and 

 highly bituminous shales of the Coal formation generally." 



245. Stibnite — An important deposit of this mineral exists in the parish of Prince 

 William (York Co.), in the jn'ovince of New Brunswick, where it is contained in
