ON CANADIAN PLEISTOCENE FLORA AND FAUNA. 529 



The Don deposits contain four species which also occur in one or more 

 of the other localities. 



Considering the evidence of climatic conditions afforded by these 

 plants, I find in the first place that the evidence which indicated that 

 during the Don period a much warmer climate prevailed than in any of 

 the other localities is greatly strengthened. If, then, we consider the 

 Pleistocene flora as evidence of climate in comparison with the climate of 

 the present day, the following results appear: — 



Per cent, of species compatible with as warm or a warmer 



climate 44-4 + 



Per cent, of species indicative of a warmer climate. . . 27-7 + 



Per cent, of species compatible with as cool or a cooler 



climate 2407 



Per cent, of species indicative of a colder climate . . . 3 7 + 



It would thus appear that while a very few northern types found their 

 southern limit of distribution at this point, the great majority of the 

 plants — 72 per cent. — were such as belong essentially to warmer regions, 

 28 per cent, being particularly indicative of a greater degree of warmth 

 than now prevails in the same region. 



Life-zones in the British Garhoniferous Rocks. — Report of the Com- 

 mittee, consisting of Mr. J. E. Mark (Chairman), Mr, E, J. 

 Garwood (Secretary), and Mr. F. A. Bather, Mr. G. C. Crick, 

 Mr. A. H. FooRD, Mr. H. Fox, Dr. Wheelton Hind, Dr. G. J.

 Morton, Professor H. A. Nicholson, Mr. B. N. Peach, Mr. 

 A. Strahan, and Dr. H. Woodward, appointed for the pur- 

 pose of studying the Life-zones in the Carboniferous Roclcs. (Lrarmi

Since the last meeting of the Association the collection authorised by the 

 Committee to be made from the deposit of the Millstone Grit Age at 

 Eccup has reached the Secretary, and has been distributed among the 

 palaeontologists specially appointed by the Committee. Full reports from 

 these have not yet come to hand ; but the collection is rich both in species 

 and individuals, and is probably one of the most valuable that has been 

 made from the Millstone Grit. 



Considerable difficulty has been met with in the housing and treatment 

 of the large collection already received ; and this has materially hindered 

 the progress of the work for which the Committee were appointed. But 

 they are now glad to announce that the Director-General of the Geological 

 Survey, hearing of this difficulty and appreciating the great value of the 

 collection, very kindly, not only offered accommodation for the collections 

 of the Committee in the Museum of the Geological Survey in Jermyn 

 Street, but promised every facility for the study of the specimens by the 

 specialists appointed by the Committee. 



In consequence of the difficulties mentioned above the Committee felt 

 it impossible to encourage individual workers to make collections from the 

 other beds of the series until some definite resolution should be come to 

 with regard to the housing of the specimens. They are, however, glad to 

 notice that since attention has been drawn to the importance of zoning
