 the blocks on the edge of the crater with great luxuriance. 



Of Alg(B there were found 33 species. The stones rolled 

 backwards and forwards by the action of the waves, as 

 also those surfaces which remained covered at lowest tide, 

 were entirely covered with Dicurella flabellata. Most

 coitfervcBf and pale and coloured luminaricE. The breakers

 Jungermania ; of foliaceous mosses. Sphagnum (bog-moss), 

 and two kinds of Bruym. Two ferns, just beginning to bear 

 fruit, were found on the plateau, and one Lycopodium (club-
