PIScEs. 
There appear to be three or four species of fish in the Oriskany 
Sandstone and Corniferous Limestone, one or two of them covered 
with plates resembling those of an Asterolepis. Dr. Newbury 
informs me that one of them is his Agassizicthys Sullivanti.

Nearly all of the species above given as determined will be found 
noticed in the several papers published in this Journal. Among 
those undetermined there must be a great many identical with those 
described in the publications of American Geologists. I shall endea-

BY E. J- CHAPMAN. 
PROFESSOR OF MINERALOGY AND GEOLOGY IN UNIVERSITY COLLEGE, TORONTO. 
The Klaprothine or Lazulite is comparatively a rare mineral. It 
appears to have been first recognized by Widenmann in 1791, in the 
valley of the Muhr, near Krieglach in Upper Styria. By Werner, it 
was mistaken for Feldspar ; and, although examined by Klaproth, its 
true nature was not detected until the analysis by Fuchs of specimens
