At Snowdon, from its greater proximity to the ocean, this 
change in the summer and winter temperatures will be less. If 
we suppose it to be 2°, we shall then have for Snowdon (see 
Table, § 13, p. 77,)— :

18° or 20° only. This actnal case, however, presents a good 
standard of comparison for our hypothetical case. The Falkland 
Islands, situated in lat. 50° S., and the island of S. Georgia, in 
lat. 54°'S., furnish also good standards of comparison. The con- 
ditions of the station above mentioned in western Europe (long. 
10° E.), and Snowdon, of which the latitude is 53° N., would, 
In'the ease we are discussing (that of the absence of the Gulf- 
stream, and the submersion of Europe), far more resemble the ac- 
tual “conditions of all the above places than they do at the 
present time. We have for the Falkland Islauds,—

Here the mean temperature is 4° less than the estimated mean 
temperature of Snowdon; and the approximation to uniformity 
of temperature throughont the year much greater. 
~The table given above ($ 17, p. 82) shows the tendency, as I 
have already remarked, of the predominance of sea to equalize the 
simmer and winter temperatures ; and this is in accordance with 
ine fact that there is a greater equality of those temperatures in the 
“alkland Islands and §. Georgia, than in the corresponding north-
