proximal position of the Hood in relation to the shingle on 
which it rests, there seem to be good grounds for believing that the 
Long Hills are the more recent formation, but that, owing to 
the conditions in which smallness of area may have played a 
considerable part, the Hood has scarcely kept pace in the 
process of colonisation. 
The relations between the two are best brought out by a 
comparison of the subjoined list of species and frequencies with 
that given for the Long Hills on p. 530.
