258 W. G. Fearnsides—Lower Ordovician Rocks of Scandinavia. 
discussed for the first time, I have passed over all questions of 
paleontology and constitution of the various sub-faunas with a brief 
reference to the work of the Scandinavian geologists, and have quoted 
only such fossils as actually fell to my hammer. 
In searching out the exposures discussed I have made full use of 
the maps and memoirs of the Swedish Geological Survey, and in 
addition have enjoyed the advice of and conversation with such eminent 
geologists as Professors Tornquist, Brogger, Moberg, and Docents 
Wiman and Kjaer, to whom, as well as to other authors of maps and 
papers, I would tender my warmest thanks. In the course of my 
travels and in the working up of my field notes I have found the 
following papers most useful, and those who wish to pursue the 
subject further may be referred to them. JI have arranged the 
references geographically in the order of the districts visited, and in 
the body of the paper shall refer to them by the letters and numbers 
appended.
