MINEEALS OCCUEEENG IN CANADA. 105 



ADDENDA. 



Since the preparation of the foregoing list, the following additional minerals 

 have been identified as occurring in Canada: 



1. BouKNONiTE — Was identified by Mr. R A. A. Johnston in samples of ore (sent to the 



survey for assay) from the following localities in the province of Ontario, viz., lot 18, 

 range 8, of the township of Marmora (Hastings Co.), the material in this instance 

 consisting of bonrnonite in association with small qnantitics of chalcopyrite and 

 pyrite in a gangue^ of quartz ; and from the east half of lot 22, range 3, and west half 

 of lot 22, range 4, of the township of Darling (Lanark Co.), the material from the first 

 of these two localities consisting of bournonite disseminated through a somewhat line 

 crystalline dolomite, while that from the last mentioned consisted of bonrnonite with 

 some chalcopyrite in a gangue of white sub-translucent quartz. 



2. Hyalite — Good specimens of this mineral were obtained by Mr. J. McEvoy from 



cavities in a dark grey foliated basalt occurring near Hîh-hûm Lake, sonth of Loon 

 Lake, British Columbia. 



3. Lepidomelane — Was recognized by Mr. R. A. A. Johnston in a sample of ore from the 



townshiiJ of Marmora, Hastings county, province of Ontario. The material consisted 

 of a fine graunlar arsenopyrite, through which was distributed a somewhat large 

 amount of lepidomelane and a little white sub-translucent quartz. 



4. MiCHEL-LÉVYTE — Barium sulphate crystallizing, according to A. Lacroix, in the 



monoclinic system (Comptes Rendus, vol. 118, p. 1126). The locality of occurrence, 

 which is described as being near Perkins' Mill, is on lot 12, range 12 (about three 

 miles, following the path, from Perkins' Mill) of the township of Templeton, Ottawa 

 county, province of Quebec. Material from this locality has been examined by Dr. 

 Edward S. Dana, who informs me " that he finds it to possess peculiarities in cleav- 

 age and lustre like those noted by Lacroix, which, however, he is disposed to regard 

 as due to pressure. It differs from normal barite chiefly in the peculiar development 

 of one of the prismatic cleavages. No variation in optical character from the require- 

 ments of the orthorhombic system was observed, while the optical properties are 

 throughovit those of ordinary barite." See " On the Barium Sulphate from Perkins' 

 Mill, Templeton, province of Quebec, by Edward S. Dana." Am. Journ. Sci., 3rd ser., 

 vol. xxxix, p. 61, 1890. 



5. Prase — A breccia, consisting of angular fragments of prase cemented together with 



white chalcedony, was found by Dr. G. M. Dawson filling cavities in Tertiary basaltic 

 rocks in mountains at head of Nicoamen River, British Columbia.
