and he now proposes to give in a connected form the results of his 
researches. This first part treats more particwarly of the oldest 
series of the Archean rocks, which is developed throughout the 
island bordering the coast, from Lofoten to the North Cape, and on 
the deeply indented coast-line of the mainland, and again makes 
its appearance in the interior of the country near the border-line 
between Norway and Finnish and Swedish Lapland. The rocks of 
the littoral or western series are named by the author gneiss-granite, 
whilst those of the Eastern are termed the inland granite. Between 
these series, which have a generally south-west to north-east direc- 
tion, there is a belt of newer crystalline schists about 100 kilométres 
(62 miles) in width, which the author believes to be deposited in 
a basin-shaped depression of the older rocks. 
The gneiss-granite series consists of beds of gneiss intermingled 
with granite, but the granite presents no evidence of having been 
subsequently intruded into the gniess; it is of the same character 
as the gneiss, and there is a gradual transition from the one into the 
other. There are also frequent beds of pure quartz interdeposited 
iu the gneiss-granite series. The author believes that all these 
rocks are of sedimentary origin, and that the materials of the gneiss 
have been derived from older granitoid rocks, which could not have 
been situated in the Scandinavian Peninsula or to the east of it, 
but probably existed in the area now occupied by the North Atlantic 
Ocean. From this supposed ancient continent the author believes 
that the Laurentian gneiss of North America was also derived, as 
well as those newer crystalline schists which fill up the basin formed 
by the gneiss-granite series in the Scandinavian Peninsula. These 
schists reach a thickness of 1000 métres, they are quite unfossiliferous, 
but they are believed to belong to the Cambrian or lowest Silurian 
epoch. 
The author gives an orographical review of the region and detailed 
descriptions of the geological structure of the different islands, as 
well as vertical sections in the accompanying plates. G. J. H.
