New York AcADEMY OF ScIENCES, Dec. 9, 1878.—Prof. Henry 
Wurtz exhibited a large series of the minerals from the Silver 
Islet, Lake Superior, and described under the name of Huntilite 
(in honor of Prof. T. Sterry Hunt), a new species of silver ore 
from that locality. Huntilite occurs both massive and minutely 
crystallized, and is essentially an arsenide of silver, occupying the 
gap in mineralogy between dyscrasite and domeykite ; dyad metals, 
especially nickel, appear to have replaced some part of the silver, 
and antimony a small part of the arsenic. Prof. Wurtz gave 
minute and laborious analyses and many interesting details.
