8. The Geological Survey of Canada : Report of the Section 

 on Chemistry and Mineralogy. By. G, Christian Hoffman, 

 Ottawa, 1897. — This report contains, in addition to the results of 

 numerous technical analyses, assays of ores of different character, 

 etc., also notes on some rare mineral species which have been 

 recently identified in Canada. An analysis is given of the 

 massive scheelite from the Malaga gold mining district, Queens 

 Co., Nova Scotia. Tetradymite has been found in foliated 

 masses near Liddel Creek, in the West Kootenay district of 

 British Columbia. Its corrected specific gravity was found to be 

 7*184 and the analysis by R. A. A. Johnston, after deducting 

 some 3-J$ of quartz, gave the following results : 



Te S Se Bi Pb Ag Tl 



37-29 4-45 tr. 53-69 3"63 0'94 tr. = 100. 



Altaite has been found with various copper minerals at the 

 Lake View Claim, on Long Lake, Yale district, British Columbia. 

 Its corrected specific gravity was found to be 8*081 and the 

 analysis by R. A. A. Johnston gave the following results : 



Te Pb Ag S 



43-01 54-04 2-27 0'68 = 100. 



The same locality has also yielded hessite, while the allied 

 species petzite has been found at the Calumet Claim, Kruger Mt., 

 in the Yale district, British Columbia. Stromeyerite has been 

 found at the Silver King mine, Toad Mt., in West Kootenay dis- 

 trict, British Columbia. It occurs in granular form of specific 

 gravity 6*277, and the mean of two analyses by Johnston gave 

 the following results :

The cobaltiferous variety of arsenopy rites called danaite has 

 been obtained from Monte Cristo Mt., Trail Creek, West Koote- 

 nay, British Columbia, where it occurs in indistinct crystalline 

 form distributed through the gang of crystalline calcite with a 

 little intermixed quartz. A corrected analysis by Johnston gave 

 the following results :
