I. On the Laurentian Rocks of Britain, Bavaria, and Bohemia
Published online by Cambridge University Press: 01 May 2009
Extract
A large portion of the last number of the Quarterly Journal of the Geological Society (February Ist) is justly devoted to the important subject of the Laurentian or oldest known stratified rocks, the elaboration and naming of which in North America were, it is well known, accomplished by Sir William Logan and his associates. On this occasion a memoir by that eminent geologist naturally leads the way, whilst, in the subsequent articles, the nature and structure of the Eozoon Canadense, which has been found in these rocks, are ably developed by Drs. Dawson, Carpenter, and Sterry Hunt.
