CHAPTER I. 
The country around Julianehaab is of great interest to 
geological science for more than one reason. It is the locality 
of a large number of rare minerals; it is the only part of South 
Greenland where a sedimentary rock-formation is found which 
is newer than the Archæan and Algonkian series; and, above 
all, it is remarkable for the occurrence of complexes of 
highly differentiated igneous rocks which afford extremely favour- 
able conditions for geological study. The occurrences of the 
minerals and the sedimentary formation are dealt with by pre- 
vious explorers in several publications. In the present paper 
will be found the results of a study of the general geology of 
the country and of the geology and petrography of the igneous 
rocks. 
GEOGRAPHY. 
The settlement of Julianehaab (‘‘Juliana- Hope”) is situated 
on the south-west coast of Greenland, in 60° 43’ N. lat. and 
46° 1' W. long., about 160 kilometers north-west of Cape Fare- 
well (Plate I). The entire south-west coast of Greenland is 
difficult of access by sea, the approach being barred, during 
a great part of the summer, by the Polar pack-ice which 
moves in a southerly direction along the east coast of Green- 
land but, after having reached Cape Farewell, turns off towards 
the west and the north-west. But the pack-ice provides good 
conditions for seal-hunting and, for Greenland, this coast is
