S. Williams and E. M. Kindle; Bulletin No. 244. 
"The twenty-fifth annual report of the Director of the 
United States Geological Survey." This report includes an 
account of the work of the survey from July, 1903, to July, 
1904. 
New York Academy of Sciences. Nov. 21, 1904, Prof. 
J. J. Stevenson read a paper upon "The Island of Spitzbergen 
and its Coal," illustrated by lantern slides. The speaker de- 
scribed briefly the coast of northern Norway and its geology 
and referred in some detail to Bergen, Hammerfest and other 
cities. The coal beds are of Jurassic age and the coal is pecu- 
liar in that it partakes of tlie characters of the lignites as well 
as of the true coals. 
Prof. J. F. Kemp presented an abstract of a paper on 
The Titaniferous Magnetite in Wyoming. The magnetite 
occurs in two places, fifteen and twenty miles north of Lar- 
amie, Wyoming, the former and smaller occurrence being the 
Shanton ranch, the latter and larger being on Chugwater 
creek. Both are in wall rock of anorthosyte which is prac- 
tically indistinguishable from anorthosyte occurring in the 
Adirondacks. The ores range from 20 per cent to 40 per 
cent TiO^. Thin sections show that they contain green 
spinels and one slide presents much olivine. They can be 
most reasonably explained as intrusive dikes. In this view 
the speaker agreed with Waldemar Lindgren who has pub- 
lished a brief note regarding them. 
A special meeting of the Section of Geology and ^liner- 
alogy was held December 2, when a lecture was given by 
Prof. Albrecht Penck. of the Imperial University at A'ienna, 
who is an honorary member of the academy. 
The speaker discussed "The Glacial Surface Features of 
the Alps." and gave a brief summary of some of the results 
of the twenty years of masterly work which has been done 
by him and under his direction in the Tyrol. Professor 
Penck discussed in popular language the nature of the valleys 
of the Alps and showed by means of lantern slides and a dia- 
gram how the glaciers have widened and deepened portions 
of their rock basins and produced lakes. A vote of thanks 
was passed to the distinguished guest of the evening.
