and all the other localities on Spitzhergen in richness in species. 

 The only disadvantage is, that the slates are here so loose and split 

 up by frost, that it is impossible to obtain even a piece with a few 

 square inches of surface, except by a considerable removal of the 

 broken fragments of rock.
