 the rocks and the specimens found in them, and he might say that 

 without having seen and examined the specimen referred to, he had 

 some little doubt on the matter. The true Eozoon canadense had 

 hitherto only been found in the Laurentian rocks of Canada, which 

 were believed to be the oldest in the world, and though there was no 

 difficulty in identifying good specimens, there was very great difficulty 

 in the identification of bad ones, and it would be found that most of 

 the troubles which had arisen in connection with this subject had 

 been from bad specimens. One of the burning questions of the 

 present day amongst geologists was the age of the rocks in the North- 

 West of Scotland. The Geological Survey had considered them to be 

 of late Palaeozoic age, but there were other observers who thought 

 them as old in origin as the Laurentian of Canada. Years ago Sir
