new collections of minerals and rocks which he has kindly 
placed at my disposal for the preparation of the present paper. 
He also made some geological observations with special reference 
to the red sandstone!. In 1897, under the auspices of the 
“Commission for the Direction of Geological and Geographical 
Explorations in Greenland”, Dr. G. Funk, of Stockholm, investi- 
gated the mineral localities north-east of Julianehaab and dis- 
covered a great number of new and interesting mineral species, 
which have been described by Dr. Fix and others”; in his 
report, however, Dr. Frink touches only cursorily upon geologi- 
cal questions. 
In 1899 the ‘‘Commission for the Direction of Geological 
and Geographica! Explorations in Greenland” enjoined the in- 
vestigation of the igneous rocks of Julianehaab upon the present 
author, and, as a preparation, I visited the Christiania district 
together with Mr. O. В. Boca who was to take part in the 
expedition to Julianehaab in the following year. Owing to Pro- 
fessor BRôcGer’s kind help we had an excellent opportunity of 
studying the large igneous complex of this distriet which, as 
is well-known, has formed the basis of some of the most clas- 
sical investigations in the department of petrology. 
The results of the explorations in 1900 will be found in 
the present report. A few supplementary observations which 
the author was able to make during a short stay at Julianehaab 
in July 1908 have been included.
