« COLOURING en or THE Rep Sra.—Mr. H. J. Carter, in the * Annals 
of Natural History’ for March, 1863, writes that Trichodesmiwm Ehrenbergii, 
the Oscillatoria that colours the waters ^ - gie qp. is more frequently 
yellow than red, and only occasionally analogy, he considers 
that the green is the original colour of de me d consequently suggests 
that as much of Montagne's generic character as relates to its colour should be 
reversed, viz. “primo rubro-sanguinea, tandem viridis.” He has also ascer- 
tained that it occurs in the Indian Ocean and the Sea of Oman as well as in the 
Red Sea, thus establishing the correct observation of the Greeks, who applied 
the name “ Erythrzan" to all the seas which washed the shores of Arabia.

There are, doubtless, many who will remember the collection of the 
“vegetable products of Norway " in the late International Exhibition, 
and who felt surprised when they learnt, perhaps for the first time, that 
even at Alten, in West Finmark, under the same parallel of latitude 
(70°) under which the ice-bound and barren regions of Victoria Land, 
Disco Island, etc., are situate, both agriculture and garden cultivation 
can be successfully carried on. The fact is, that Norway enjoys à far 
wilder temperature than any other country in the world under the 
same latitudes, owing to the influence exerted by the Gulf Stream. 
This remarkable current impinges on the Norwegian coast, somewhere 
about lat. 62°, and follows it at a greater or lesser distance to the Rus- 
sian frontier on the Arctic Ocean. In consequence of this, the sea 
never freezes along the whole extent of the western and northern coasts. 
But this is not the only influence. The long days of summer, or, in 
other words, the continued light, play a most important part in the ve- 
getation of the country; and while the earth does not therefore become 
so cooled during the short nights, as is the case in more southern climes, 
vegetation continues day and night without interruption. Dr. Schiibeler 
devotes several pages to a consideration of the various theories that
