EDITORIAL 755 
Ir 1s pleasant to announce that our colleague of the JOURNAL 
staff, Dr. Hans Reusch, has been engaged to give two courses 
of lectures at Harvard University during the current year. In 
the first half of the year he will treat of vulcanism, volcanoes, 
eruptive rocks, earthquakes and other movements of the Earth’s 
crust. In the second half he will describe the geology of 
northern Europe and its relations to general geology. He will 
give a weekly seminar to advanced students and will take part 
in their field and laboratory work, his special subjects being the 
geology of the seashore and the geology of special districts in 
Europe. These lectures are given on the Sturgess- Hooper 
foundation recently occupied by Professor J. D. Whitney, but 
vacant since his death. (es
