9A THE SEA SCUM AND ITS NATURE. 
the Nostocacez, although Mr. Francis is of opinion that the Alga 
may be referred, on what grounds 1 know not, to Nodularia 
spumigera, an ally of Protococcus. 
Not long since, cattle on St. Helena, Moreton Bay, were 
observed to be dying from the effects of some poison in a 
mysterious manner, and Mr. F. M. Bailey, the Colonial Botanist, 
on an examination of the vegetation of the island, has been, I 
believe, unable to assign a cause for this state of things. After 
reading these observations of Mr. Francis, I can scarcely avoid 
the conjecture that the sea scum of the Bay which has 
indicated its presence by disseminating perfumes, other than 
those of Arabie, may also be in some way responsible for these 
incursions into the St. Helena herd.
