22 THE AECTIC FLOEA OF THE CAM TALLET. [vol. Ixxvii, 



question. In Scandinavia it seemed to be constant in its appear- 

 ance at the close of the last Grlacial episode, during the later stages 

 of the emergence which followed upon the Yoldia depression, and 

 in Grotland it occurs along with ZanniclieJlia foJijcar'pa below tha 

 deposits of the Ancyliis lake. Prof. Marr's discovery of Palaeo- 

 lithic implements at a higher level than the plant-bed provided a 

 new problem, and showed the necessity for further investigation.

The AiTTHOE thanked those present for the kind reception 

 given to her paper. In reply to Prof. Sollas, she regretted that, up 

 to the present, no comparison with the Pleistocene floras of the 

 Continent had been made. She ventured to differ from Mrs. Peid 

 as to the extermination of the Temperate flora b}^ the cold ; for, 

 although the Cromerian species found in the Lea and Cam floras 

 were few, the species recorded from the Cromerian would constitute 

 but a small proportion of the Temperate flora then living, and 

 there was no dearth of Temperate species in these two Arctic beds, 

 for such constituted 78 and 08 per cent, of these floras respective!}". 

 A certain element comprising the more southern forms was doubt- 

 less exterminated ; but, pending further discoveries, she felt that 

 the presence of so large a proportion of Temperate species associated 

 with the Arctic species pointed to the fact that, far from being 

 exterminated, much of the flora was able to endure the changed 

 conditions, and to live on side by side with the Northern invaders.
