The foregoing list of plants from Northumberland and Cumberland contains the 

 species from all the divisions of the Calciferous Sandstone series of that area ; and with the 

 purpose of comparing the fossil plants from the same rocks of Dumfriesshire with those 

 from the North of England a table is given, showing in the first column the fossil plants 

 from the North of England, the second column contains the Dumfriesshire specimens, 

 while the third column shows the further distribution of these plants in the Calciferous 

 Sandstone series of other areas of Scotland.
