226 ARCTIC PLANTS DURING THE POST-GLACIAL EPOCE. 
Philonotis fontana, Brid., Bryum Lagee e Swartz., B. pseudo-trique- 
trum, Schw., Amblystegium estas Schimp., A. filicinum, Lindb., 
Timmia megapolitana, W., : wre a, and Climacium 
dendroides, Web. et Mohr. The Liverwort Metzgeria furcata, Nees ab 
neta Shs also found with the Mosses; and the following animal 
re —Cytheridea torosa, Jones, Pistlium pulchellum, D’Ord., P. 
S castoibtaniien, Shepp., Limnea limosa, and Anodonta. Some leaves 
and seeds besides those recorded were also found, but I have not yet

osit containing the . -remains rested on the till o 
boulder diy (moraine profonde), an d was therefore formed as the ice- 
sheet melted away. It is generally covered by beds pf peat-moss s, from 
which there have been obtained a constant series of different trees like 
i k 
peat-mosses in Denmark, and this I was enabled - ssa and happily 
with the assistance of Prof. J. Steenstrup, The results here were 
the same asin Scania. These will be better mpderstosd by the fol- 
lowing table, which at the same time shows the changes of climate 
which followed the glacial epoch :-— ;

of 1872'I visited Mecklenburg, in Germany, and 
found a Some of Betula w nana, Linn., in a peat-moss there. In a peat- 
Uyrtillus uliginosa, Drej., Andromeda polifolia, Linn., &c. 
formed a distinct layer in the moss at this locality, which could be 
traced pera the -_ of the peat-moss, showing that at one 
time a surface vegetation covered the ground here similar to that 
. which is found st "the present aay in Panty 6 inmar. 
In Switzerland I found a great pres of Arctic plants in 
locality on ths low ary between Fach nd Bodensee, at Schwe areas 
bach. The condition of things here was precisely what I had seen
