Some Pal.^obotanical Aspects of the Upper 

 Palaeozoic in Nova Scotia. 



By David White. 



Introduction. 



In a recent issue of the Transactions of the Nova Scotia 

 Institute of Science^ Mr. Hugh Fletcher, geologist of the 

 Canadian Survey, presents correlations of the Upper 

 Palaeozoic formations by paleontologists in marked con- 

 tradiction with stratigraphic determinations by himself 

 and other geologists in Nova Scotia. Confident of the 

 validity of identification on stratigraphic evidence only, 

 he rejects the palseontological correlations, which he finds 

 incompatible with the supposed order of succession of the 

 strata, as well as totally erroneous as to the age of the 

 terranes. The difference of statement involves broad 

 questions, such as the reference of formations to one great 

 period or another, to middle Carboniferous or middle 

 Devonian.
