this locality, consist of Native Silver in prongs and filaments, 
as well as distinctly crystalline in structure, all of them 
imbedded in Calcareous Spar, which has been in some cases 
removed by means of a dilute acid, and the metal exposed. 
These resemble very closely, specimens from the Gould and 
Curry mine, in Nevada, as also the Swedish Ore. And 
there would seem to be little room for doubt as to this new 
locality proving a prolific one in other respects than silver, 
for the reason that a Speiss obtained from the roasted ore 
contains both Cobalt and Nickel in considerable quantities, 
and, in nearly every character, resembles very closely a 
Speiss imported many years since, from Saxony, for the 
purpose of refining and manufacturing German Silver. This 
Speiss contained 50 per cent. of Nickel and 10 per cent. of 
Cobalt, besides Arsenic and Iron, A hasty examination of 
the Lake Superior specimen, shows it to consist of these 
metals, besides some Copper. The importance of this dis- 
covery will be the more fully appreciated, when it is 
remembered for how many purposes Nickel is now used in 
the arts. Not alone is it employed for the manufacture of 
German Silver, but the newly-introduced process of Nickeliz- 
ing or plating other metals with Nickel, and which would 
seem to be destined to a great extent to replace Silver plating 
calls for a large supply. A company are successfully working 
this mine, paying to the Canadian Colonial Government, the 
very moderate royalty of twenty dollars the ton of ore. 
The President, Dr. J. S. NEWBERRY, made some remarks 
On Recent Deep-Sea Dredgings. 
He described the swzte of specimens collected by Count 
Pourtales, in his two seasons of dredging off the southern 
coast of the United States, in the service of the Coast Survey. 
The points of special interest in these explorations were, first, 
the division of the sediments accumulating off our coast into 
two distinct belts, the mechanical, and the organic, with a line 
of junction between the two, where their characteristics are
