1888. ] NEW YORK ACADEMY OF SCIENCES, 3 
In a mica schist on the site of the Old Men’s Home, Fort 
George, staurolite in brilliant dark brown doubly-terminated 
crystals, one-third of an inch long. 
Ophiolite and serpentine, the result of an alteration from 
pyroxene, from the excavations at Aqueduct shaft No. 26, 180th 
St. and Tenth avenue. 
Also, from Colorado, turquoise resembling the Los Cerrillos 
variety, the color a deeper and better blue, occurring in veins of 
feldspathic granite, from the Holy Cross Mining District, thirty 
miles from Leadville. 
Dr. H. C. BoLton gave some account of his visits during the 
summer to a number of scientific libraries in Austria, Germany, 
France, and England. In several of these institutions, he had 
found an extraordinary lack of facilities for research, so much 
so as to render them absolutely useless to the original investi- 
gator. In others, however, he had been gratified to find better 
ideas and methods prevailing; but these were in the minority. 
Dr. N. L. Brirron described briefly his summer spent in 
botanical studies in the Herbarium of the Kew Gardens. He 
had taken over the undetermined portions of Dr. RusBy’s col- 
lections from Brazil and Bolivia, for comparison and identifica- 
tion so far as possible. As a result, he found that Dr. Rusby 
had secured between two and three hundred species new to 
science. ‘These would soon be described and published. 
Dr. FRANZ Boas stated that he had visited the region of 
Queen Charlotte Island, and the interior of British Columbia, 
in the prosecution of ethnological studies. He was led to be- 
lieve that the Tlingit and Haida tribes belong to one and the 
same stock, but not the Tsimshian, nor the Southern tribes, 
which form yet another group. The folk-lore shows the close 
relation of the first and second; a study of the legends proves 
that to some extent even the Sioux folk-lore reached and influ- 
enced the tribes of the Pacific coast. 
THE CHAIRMAN referred to a search for oil undertaken in the 
Triassic basin of Southbury, Conn., and discussed somewhat 
the geology of that region.
