CONCLUDING NOTE TO PART II. 
The minerals of Canadian occurrence —including both the very rare and the 
doubtful species, such as native Platinum, occasionally found in small grains with 
the Native Gold of the Riviére du Loup; and the altered substances, Renselaerite 
Pholerite, &c.,—amount in number to about seventy. Many of these are of more 
or less local occurrence, but others, on the contrary, are comparatively common. 
These latter are collected together, and arranged in accordance with their more 
obvious characters, in the Table annexed to this Note. The less experienced 
reader, consequently, may avoid some trouble in the determination of an unknown 
mineral, by consulting this Table in the first instance. If the specimen under 
examination do net agree with the species here cited, the recular Table given at 
page 170 of Vol. V., can then be referred to. In case of agreement also, recourse 
may be had to the latter as a confirmatory test.
