Director of the Geological Survey of Canada. v 



Sir, 



The Report which by your request I have the honour to 

 present herewith, includes the results of researches in the Devonian and 

 Upper Silurian Flora of Canada, prosecuted for several years, and now 

 brought to a conclusion, so far as the material at present accessible will 

 permit. 



For the purpose of these researches I have had in my hands the collec- 

 tions of the Geological Survey of Canada, and those made by Prof. 

 Hartt for the Natural History Society of New Brunswick, and I have 

 myself visited and largely collected in all the more important localities. 

 I have also had the opportunity of studying the fossil plants collected by 

 Prof. Hall in New York, and by Prof. Newberry in Ohio, and the more 

 important collections in Great Britain. 



I shall be able in the present Report to catalogue or describe more than 

 one hundred and twenty species of Land Plants found in forma- 

 tions older than the Carboniferous in Canada and the neighbouring parts 

 of North America ; thus placing the knowledge of this old flora as it 

 occurs in Canada, in advance of that of any other portion of the world.
