2. On Native Lead from the Northwest shore of Lake Superior ; by 
Prof. E. J. CaapMan, of Toronto As. a natural product, lead is tal

namely : Bat vein, traversing limestone (of oa geological 
age), near _notohianienre in the Province of Vera ruz, in Central Mex- 
ico. The specimen, from the locality now under consideration, was 0 
tained by Mr. McIntyre, of Fort William, at a spot near the celebrated 
Dog Lake of the Kaministiquia. The lead occurs in this specimen—the 
only one, I believe, discovered—in the form of a small string in white 
semi-opaque quartz. The quartz, which constitutes a narrow vein, does 
not appear to contain the slightest speck of galena, or of any other sub- 
shinies except a small quantity of specular iron ore; and the unaliered 
appearance of the latter is such as to preclude the supposition of the lead 
having been derived from galena, or other lead compound, by artificial 
heat. Before coming to my hands, the specimen had been examined by 
Mr. T. W. Herrick, whose extensive surveys and explorations in this re- 
gion are so well known, and by him it was looked upon as metallic lead.
