Mar. 1832. 



however, there is a very great difficulty in imagining any- 

 one spot to be the birthplace of the millions of millions of 

 animalcula and confervee : for whence come the germs at 

 such points ? — the parent bodies having been distributed by 

 the winds and waves over the immense ocean. But on no 

 other hypothesis can I understand their linear grouping. 

 I may add that Scoresby remarks, that green water abound- 

 ing with pelagic animals, is invariably found in a certain 

 part of the Arctic Sea.
