These coincidences are too numerous to be accidental, and when 

 we consider that the rocks compared are at Gaspe and Arisaig on 

 opposite shores of the Gulf of St. Lawrence, with Prince Edward 

 Island only intervening, identity can scarcely be questionable. 



The evidence of fossils is a desideratum for the complete solution 

 of the problem of the age of these metamorphic rocks of Arisaig. 

 At one time it was supposed by some that this evidence was also 

 available. The discovery of the supposed Eozoon Canadense wf 

 considered as conclusive proof of the Laurentian age of the Arisaig 

 serpentines. It was afterwards found that the tubulation of the 

 Arisaig fossil was different from that of the Eozoon Canadense, 

 and it was considered by Dr. Dawson that the rock in question 

 might consequently be of later age. I must confess that I never 

 attached much importance to the discovery of the supposed fossil, 

 and consequently I always regarded its existence as proof of any
