Forty-three persons present. 
The Librarian, Dr. N. L. Brirron, read a list of Accessions

Pror. D. S. Martin and the PRESIDENT spoke of the recent 
decease of two eminent archeologists whose names had long 
been associated, E. G. Squier and KE. H. Davis. 
Pror. W. Le Contre SreEveENns referred to the work of the 
Brooklyn Institute, and, as an officer of the institution, he ex- 
tended to the members of the Academy an invitation to attend

Mr. WittiAmM E. HippEN announced the discovery, in Mr. 
Niven’s collections from New York Island, of the following 
minerals new to the locality :—chrysoberyl, a fairly good crystal, 
lying in feldspar ; zircon (?), showing the unit and secondary 
prisms, unit pyramid, and the common zirconoid (3—38) ; mon- 
azite, having the characteristic monoclinic form and basal cleav- 
age, but with density of 5.5, (commonly 5.1 to 5.3) ; autunite, 
in bright, light-green micaceous crystals; also gummite, and 
possibly uraninite and uranotil. The uraninite is a cubo-octa- 
hedron, as yet in its matrix, but its form and its associations in- 
dicate its identity. ‘These minerals are from the pegmatite 
veins in the gneiss near Fort George. 
Mr. HIDDEN read an article from a North Carolina paper, 
The Landmark, relating to the mining of zircon. Mr. Hidden 
and Mr. M. H. Mallory, of New York, had contracted to deliver 
50,000 poundsof that mineral. Work wascommenced in.October 
last upon the Freeman and Jones lands on Green river, Henderson 
County, and at the present date the delivery was almost com- 
pleted. The mining operation was similar to gold washing,
