rocks of Canada. ‘The writer may not be quite astray when he 
asserted, instead of fishes, it actually represented the culminating 
age of corals. 
Professor Schuchert, of the Smithsonian Institute, expressed 
astonishment at the vast piles of corals collected by the farmers from 
the surface of their fields in Ontario, rather in the part he visited 
(Thedford). 
I have already called the attention of the Section to the upper 
glaciated bed at Limeridge. What is known to us as the Stromato- 
pora band there, contains numbers of corals of the honey-comb 
species chiefly, what perhaps may be looked upon as a reef, the 
joint production of Protozoz and Zoophytes. 
The layer itself is very massive, of considerable hardness, and 
you may find much difficulty in extracting even a tolerably preserved 
specimen from it. A few shells in very poor preservation, so imper- 
fect, in fact, that they could not be recognized, were noticed in this 
layer some few years ago.
