594 General Notes. (uly, 
Markham’s “ Polar Reconnaisance,” Sir Joseph Hooker, in treat- 
ing of the botanical specimens collected in this voyage to Novaya 
Zemlya observes: ‘Comparing, then, the floras of the three 
high Arctic meridians of Novaya Zemlya, lat. 70°-77°, long. E. 
60° ; Spitzbergen, lat. 7614°-8014°, long. E. 20° ; West Greenland 
and Smith’s Sound, &c., lat. 71°-82°, long., W.60°—70°, we find that 
they present great differences, Greenland being the most remark- 
able: 1. From the number of species of European types it con- 
tains which there reach so very high a parallel. 2. From differ- 
ing more in its flora from Spitzbergen and Novaya Zemlya than 
these do from one another; and, 3, From the absence of Arctic 
Leguminose, Caltha and various other plants that extend eise- 
where around the Arctic circle. These facts favor the conclusion 
which I have expressed in the Appendix to Sir George Nare’s 
Narrative (11, 307), that the distribution of plants in the Arctic 
regions has been meridional, and that their subsequent spreat 
eastward and westward has not been sufficient to obliterate the 
evidence of this prior direction of migration. To this conclusion 
I would now add that whereas there is no difficulty in assuming 
that Novaya Zemlyaand the American Polar Islands have been pe 
pled with plants by migration from the south, no such assumption 
will explain the European character of the Greenland, and espe 
cially the high Northern Greenland vegetation, the main features 
of which favor the supposition that it retains many plants which 
arrived from Europe by a route that crossed the Polar area. itself 
when that area was under geographical and climatal conditions 
which no longer obtain.”——In a lecture delivered recently be-
