THE NATURALIST. 



tains t whilst in Spitzbergen it is always cold, moist, and frozen at a few 

 inches below the surface. The soil of the Faulhorn is then too warm for 

 Spitzbergen plants, and not humid. The terminal cone composed of a disin- 

 tegrated black limestone, is dry and arid when the snows have disappeared 

 whilst the soil of Spitzbergen is always humid and even spongiose, in all 

 those parts where vegetation is developed. The other plants which grow on 

 the terminal cone of the Faulhorn, are plants of the north of Europe, alpine 

 species or those which in the Swiss plains or the inferior mountainous 

 regions, are elevated to the summit.
