Mosses ; they form more than a quarter of the whole Flora of Melville Island • and the 

 black and lifeless soil of New South Shetland is covered with specks of ]\losses stVucfo'linff 

 for existence. How they find their way to such places, and under what laws they are 

 created, are mysteries that human mgenuity has not yet succeeded in un veiling. The 

 Sphagna occupy vast tracts of morass with their spongy stems and leaves. 



The shght astringency and diuretic qualities of Polytrichum and others caused them 

 to be formerly employed in medicine, but they are'now disused. In the economy of 

 man they perform but an uisignificant part ; but in the economy of natm-e, how vast an 

 end ! Sphagnum forms part of the food of the reindeer ; and in the polar regions the 

 inhabitants dry it and make it into a sort of bread " miserse vitte dehcias." Endl.
