I.—NOTES ON CONCRETIONS FOUND IN CANADIAN Rocks.—By 
T. C. Weston, F. G. S. A., LATE OF THE GEOLOGICAL 
SURVEY OF CANADA. 
(Read 14th January, 1895 ). 
Every student of geology is familiar with concretionary 
matter. I purpose in this short paper giving descriptions and 
illustrations of a few of the more interesting forms. 
The resemblance of many concretions found at various 
horizons of our Canadian rocks, to some of the Monticuliporide 
and Stromatopora of the Trenton, Chazy and other formations 
has often caused them to be mistaken for these fossils. Notes 
by the writer in Trans. of the Nova Scotian Inst. of Science.

Huronian Rocks of Newfoundland.
