On Metallic Minerals. 381 



NOTE 2. 



For information respecting the ore in rear of St. Paul's 

 Bay, I beg leave to refer tlie Society to my communication 

 on the subject, in the 1st and 2cl vols, of its Transactions, 

 pages 145 and 7^- 



The only new fact I have to communicate on the subject 

 is, that a fragment of the ore which has been left neglected 

 in a daik corner for some time, is now found to possess 

 polar magnetism, although it previously was found to be 

 deficient in any kind of magnetic influence whatever, before 

 it was roasted, and which circumstance was particularly 

 stated in one of the communications alluded to above. 



NOTE 3. 



The Gatineau river enters the Ottawa from the northward, 

 about one mile and a half below the entrance into the 

 Rideau Canal. It is navigable for steam-boats for about 

 four miles upwards from its confluence with the Ottawa, — 

 here rapids occur. About one mile and a half west of these 

 ra[)i(ls, a bed of iron ore is met with. It is situated near the 

 summit of a mountain, in the t()wn>hip of Mull, L. C. and 

 form^ a vein or bed in the former from ten to twelve feet 

 thick, it appears to traverse the mountain on a south-west 

 course, having a vertical position as regards the walls of 

 the vein. On the opposite side of the mountain, at the 

 distance of upw^irds of a mile, and in the direction of the 

 vein, ore was again seen in great abundance. From the 

 f|uaiitily of ore seen in these two places, as well as in other 

 parts of these high lands, no doubt is entertained that there 

 IB a considerable deposit of ore in this portion of Ijovver 

 ( unada.
