Prof. Theodore Kjerulf has very carefuily investigated 
this part of the Cambrian in Norway, where it is known as 
the Sparagmite formation. He divides it into two parts, 
viz.:—l. (Upper) Blue quartzite and quartziferous sand- 
stones 310-500 metres (about 1000-1600 feet) thick. 2. 
(Lower) Grey and red sparagmite, also conglomerates and 
sandstones 630-910 metres (2000-2900 feet) thick. 
In this formation, no fossils are known in the lower divi- 
sion, but they are found at the base of the upper division. 
The genera correspond to those of Bands 6 and ¢ of Division 
1 of the St. John group, and therefore the upper division of 
the Sparagmite formation is of Primordeal age, and the 
lower will correspond to the underlying series of red rocks 
of the St. John Basin. 
It seems doubtful if this lower part of the Cambrian 
system is at all represented in Sweden. Here the oldest 
beds were first described as the ‘“‘ Fucoidal Sandstone”; 
but as the greatest thickness of this sandstone at several 
localities where it was measured by Hisinger, Wallin and 
Sidenbladh, did not exceed eighty feet, it seems impossible 
that this sandstone represents the great mass of sediments 
which in Norway, Britain, Newfoundland and Acadia, lie at 
the base of the Cambrian system; it seems rather to cor- 
respond to the grey sandstones and dark grey sandy shales 
of Bands a and 0 of Division 1 of the St. John group, which 
in their eastern exposures have a thickness, the former of 
about 200 and the latter of some 140 feet. 
In Wales is to be found a series of beds, which, perhaps, 
more nearly than any others, correspond in mineral charac- 
ters, and in the evidence which they contain of the presence 
of living forms at this period, to the Lower Cambrian series 
of Acadia. To the zeal and acumen of Dr. Henry Hicks, 
science is indebted for the discovery which made plain the 
existence of a somewhat varied fauna in these very ancient 
rocks, previously known only to have worm burrows. By 
the organic remains which they contain, consisting of 
crustaceans, brachiopods, etc., he was able, on palzeontolo- 
gical grounds, to divide the obscure slates of the Lower 
Cambrian formation at St. David’s into the Solva Group
