32 TRANSACTIONS OF THE [Nov. 23, 
four species—the ‘Sharpshinned,” the ‘Broad winged,” the 
‘« Marsh,” and the ‘‘ Fish” hawks. 
The birds were examined and notes made of the condition of the 
wing feathers as soon as the birds reached the ground. Of the 
twenty-six birds which were shot twenty-three were found to have 
the primaries locked or overlapped along that portion of the feathers 
which were emarginately cut. 
Of the three which were counted as not having primaries locked, 
one was a fish hawk, which was at first only “‘ wing tipped” by the 
shot, and which was found flapping along the ground in the under- 
growth of the woods where it had fallen; and another was a small 
hawk which ran some distance through the bushes before being 
caught. The third was moulting and its primaries had only partly 
grown out, and but one primary was locked. 
Professor Trowbridge stated that he was present during the 
observations of the 14th of September, and many more birds might 
have been shot; but he concluded that enough had been killed to 
confirm absolutely the facts reported at the meeting of the Academy 
above referred to. 
The following papers were then read by Mr. Grorce F. Kunz: 
1. Some Observations on the Opal Mines of Hungary, and the 
Occurrence of Opal in Washington and Oregon. 
2. On the Origin of Garnets and Associated Minerals in the 
Garnet District of Bohemia and Saxony. 
Both papers being illustrated by lantern slides. 
After the reading of these papers considerable discussion ensued, 
in which Pror. Kemp, Drs. JuLreN and Brirron took part. 
Dr. Britton, calling attention to the approach of Christmas, 
moved that when the Academy adjourns on December 21st it do 
adjourn until January 4th, 1892. Carried. 
Mr. GARRETTSON called attention to the death of Dr. Joun C. 
Jay, the oldest member of the Academy, formerly active in the 
Lyceum of Natural History, and its Treasurer from 1836 to 1843. 
His valuable conchological collection was bought by Miss WOLFE 
and presented to the American Museum of Natural History, Cen- 
tral Park. Dr. Jay became a member of the Lyceum in 1832, and 
died last week. 
Meeting adjourned.
