26 Canadian Record of Science. 
Norway, Britain, Newfoundland and the eastern provinces 
of Canada afford unusual facilities for the study of these old 
Cambrian formations, and in the above table, an attempt 
has been made to co-relate these rocks from the information 
thus far gathered as to their mineral composition, strati- 
graphy and faunas: 
The double cross line in the above table indicates the 
point at which a break in the succession of beds occurs in 
the Cambrian system in America. 
It may be remarked that the lower series in Acadia, 
though unconformable to the St. John group, is closely 
related to it in its distribution. 
FAUNA OF THE LOWER SERIES. 
Hitherto we have been accustomed to look upon the 
assemblage of organisms found in Division 1. of the St. 
John group as the first link in the chain of paleeozoic faunas 
in America, but investigations made during the last summer 
compel me to modify this view. That there were earlier 
forms of life in the measures at the base of the paleozoic 
systems, seemed probable for various reasons, and it had 
been asserted of the Intermediate system in Newfoundland, 
which Mr. Murray has classed with the Huronian, that in 
it two obscure forms did exist; but neither in Newfound- 
land nor on the continent of America, so far as the writer 
is aware, have any organisms been described from these 
basement beds of the Cambrian system proper. 
Such being the very imperfect condition of our knowledge 
of the pre-Primordeal life of the Cambrian system in 
America, a very small addition to the information on the 
subject may be of value, and the few observations on the 
fauna made in New Brunswick are therefore presented 
here. 
A barren sandstone, Band a of Division I, some two 
hundred feet in thickness, cuts off the fossiliferous horizons 
of the St. John group from all below; but as the Lower 
Cambrian series is now found to contain vestiges of organic 
life, down almost to the base, the fauna marked by Para- 
doxides may no longer be regarded as the oldest paleozoic 
fauna in America. ©
