I trust, therefore, that this Report, like Goeppert's and Unger's on the 

 Devonian Flora of Europe, will, for some time at least, constitute a 

 standard work of reference on this subject, not only in this country but 

 abroad. It will also, no doubt, tend to stimulate further discoveries, and 

 will afford to working geologists in this Dominion a satisfactory basis for j. 



the comparison of the Devonian and Carboniferous plants, a point very ^ 



important in the investigation of our Coal-fields. 



The descriptions in this Report are, with a few additions, and some 

 changes rendered necessary by the more special reference to Canada, the 

 same with those in my memoir on the Devonian Flora of North Eastern 

 America, read before the Royal Society of London in 1870, and now in 

 its archives. 



I have the honour to be, 



Your obedient Servant, 



J. W. DAWSON.
