86 HOFFMANN'S LIST OF 



119. Hematite — Important deposits of red hematite are met with at several localities in 

 Pictou and other counties in Nova Scotia. It occurs, in association with specular 

 iron ore, among the Huronian strata of the Quaco hills, and more abundantly in those 

 of West Beach and Black River, St. John county, province of New Brunswick. 

 Forms an extensive bed in the township of McNab (Renfrew Co.), and is further 

 found in the townships of Dalhousie and Beckwith (Lanark Co.), Palmerston (Fron- 

 tenac Co.), Madoc (Hastings Co.), Leeds (Leeds Co.), etc. — at Gros Cap, north side of 

 Michipicoten Harbor, and other localities in the Lakes Superior and Huron region, 

 province of Ontario. See also notes to " Micaceous iron ore," " Specular iron ore," 

 " Martite." Mineral associations of hematite, B. .1. Harrington, Rep. Greol. Can., 

 IBYS-H, p. 212. Analyses, by various analysts, ib., pp. 223-226, and subsequent 

 Reports. 



120. Heulandite — Fine specimens of this mineral are met with at Isle Haute, Partridge 

 Island, and Two Islands (Cumberland Co.), also at Black Rock, Hall's Harbor, Long 

 Point, and Cape Blomidon (King's Co.), in the province of Nova Scotia. 



121. Hornblende — Black crystallized hornblende enters abundantly into the diorites of 

 Yamaska Mountain (Yamaska Co.), and Mount Johnson (Iberville Co.), and occurs 

 sparingly in the trachytes of Brome (Brome Co.), and ShefTord (ShefFord Co.) Moun- 

 tains : beds of black hornblende, holding garnets, are associated with the serpentines 

 of Mount Albert in the Shickshock Mountains (Graspé Co.), and black or greenish 

 hornlilende is very commonly disseminated through the felspathic rocks of the 

 Laurentian series, giving rise to syenite and syenitic gneiss : also forming beds of 

 hornbleudic rock, as at Lake St. John (Chicoutimi Co.), province of Quebec. Black 

 or dark green hornblende, in cleavable masses, is found associated with the magnetite 

 of Bathurst and South Sherbrooke townships (Lanark Co.), province' of Ontario. 

 Anal., B. J. Harrington, Rep. Geol. Can., 181S-14, p. 201. 



122. Hornstone or Chert — Occurs, in veins traversing syenite in the township of 

 GreuAalle (Argeuteuil Co.), in the province of Quebec; in great abundance, in nodu- 

 lar masses and thin layers, in the Corniferous formation, and occasionally, in a 

 similar form, in the limestones of the Trenton and Niagara groups ; also, in layers, in 

 the lower beds of the silver-bearing rocks of Thunder Bay (the lower division of the 

 Upper Copper-bearing rocks of Logan), Lake Superior, province of Ontario. 



123. Howijte— Occurs, in the form of nodules which are generally about the size of 

 filberts or pigeon's eggs, and occasionally, but rarely, as much as two inches in 

 diameter, imbedded in anhydrite and gypsum at Brookville, and in gypsum at 

 Winkworth, Newport Station, Noel, etc., in Hants county, province of Nova Scotia. 

 Analyses, H. How, Phil. Mag., 4 ser., vol. xxxv, p. 32, 1868. 



124. HuMBOLDTiNE — Has been observed as a siilphur-yellow incrustation upon the black 

 schists at Kettle Point in the township of Bosauquet, Lambton county, province of 

 Ontario. 



125. HuRONiTE — The Iluronite of Dr. Thompson — an impure or altered form of anorthite 

 — is found, in silu, near Sudbury (District of Nipissing, province of Ontario), where it 

 occurs in rounded or somewhat angular masses, in a dark green dyke of diabase. 

 Anal., B, J. Harrington, Trans. Roy. Soc. Can., vol. iv, sec. iii, p. 82, 1886. 



126. Hyacinth — Cherry-red, transparent crystals of zircon, are mentioned by Dr. Hunt
